SAUTER FM premium Force Gauges – Tension & Compression Testing

Professional force measurement with data storage, digital connectivity and integrated or external load cells

The SAUTER FM digital force gauge series provides a professional solution for measuring tensile and compressive forces in industrial quality control, mechanical testing and engineering laboratories.

In modern manufacturing, force measurement plays an essential role in verifying component performance, evaluating mechanical assemblies and maintaining consistent product quality.

The force required to extract a connector, operate a switch, compress a spring or release a mechanical fastening system can determine whether a component meets its specified performance requirements.

SAUTER FM instruments are designed to support these demanding applications with digital force measurement, practical testing functions and integrated data management capabilities.

The series comprises 13 model variants with maximum capacities ranging from 5 N to 20 kN, providing solutions for low-force component testing as well as higher-load industrial applications.

Models with an integrated load cell offer a compact configuration for handheld operation and compatible test stand mounting. Versions with an external load cell allow the force sensor to be positioned separately from the display unit, making them particularly suitable for higher capacities and specialised mechanical test setups.

With a 1,000 Hz measurement frequency, a manufacturer-specified measurement tolerance of 0.2% of full scale, Peak Hold functionality and continuous Track mode, the FM series supports a broad range of professional force-testing procedures.

An internal memory for up to 500 measurement values and USB-C and PS/2 interfaces provide additional options for storing and transferring results.

The backlit, reversible display, graphical capacity indicator and programmable tolerance limits further enhance usability in production environments and technical laboratories.

Whether used for component inspection, product development, assembly verification or mechanical quality assurance, SAUTER FM digital force gauges combine precise measurement capabilities with flexible integration options.

SAUTER FM model comparison – 13 force gauges from 5 N to 20 kN

The SAUTER FM range is divided into two principal configurations: digital force gauges with integrated load cells and instruments with external load cells.

SAUTER FM digital force gauges with integrated load cells

In these models, the force sensor is integrated into the instrument housing.

Their compact design makes them suitable for handheld force measurement and installation on compatible test stands.

ModelMaximum force capacityDisplay resolution

SAUTER FM 1K EXT1,000 N0.5 N
SAUTER FM 3K3,000 N1 N
SAUTER FM 5K5,000 N2 N
SAUTER FM 10K10,000 N5 N
SAUTER FM 20K20,000 N10 N

The manufacturer specifies a measurement tolerance of 0.2% of the maximum measuring capacity.

Display resolution and measurement accuracy are different technical characteristics and should not be treated as equivalent.

Integrated load cell force gauges – Compact measurement for everyday testing

Professional push and pull force measurement in a single instrument

SAUTER FM models with integrated load cells combine the measuring sensor and display in one housing.

This arrangement is particularly convenient for manual inspection tasks and compact testing stations.

Force is applied through suitable attachments connected to the instrument's measuring axis.

Typical applications

  • Push-button actuation force measurement

  • Mechanical switch testing

  • Connector extraction testing

  • Spring force verification

  • Plastic component inspection

  • Mechanical closure testing

  • Product development

  • Routine industrial quality control

The integrated models are equipped with an M6 external thread for compatible measuring attachments.

Advantages of an integrated load cell

  • Compact construction

  • Convenient handheld operation

  • Straightforward installation in compatible test stands

  • Direct display of measured forces

  • Suitable for mobile inspection tasks

  • Practical for repetitive component testing

The correct capacity should be selected according to the expected maximum force and the required display resolution.

External load cell force gauges – Flexible solutions for higher forces

Separate sensor and display for industrial test setups

The SAUTER FM external load cell models are designed for applications in which the force sensor must be positioned independently of the display unit.

This configuration is particularly valuable when testing larger components, working with higher forces or integrating the measuring system into a suitable mechanical fixture.

External load cells are available with maximum capacities from 1 kN to 20 kN.

Typical applications

  • Pull-out force testing

  • Mechanical connection inspection

  • Retention force measurement

  • Compression testing of industrial components

  • Load testing of suitable assemblies

  • Evaluation of fastening systems

  • Mechanical engineering experiments

  • Integration into custom test fixtures

The load cell must be mounted correctly and loaded along its intended measurement axis.

Advantages of external load cells

  • Separate positioning of sensor and display

  • Greater flexibility in mechanical test arrangements

  • Higher available force capacities

  • Easier integration into suitable fixtures

  • Reduced need to handle the measuring instrument directly

  • Adaptability to different testing geometries

The load cell, mounting components and accessories must all be rated for the expected forces.

SAUTER FM 1K vs FM 1K EXT – Choosing the right configuration

Both models offer a maximum measuring capacity of 1,000 N and a display resolution of 0.5 N.

Their primary difference is the location of the force sensor.

SAUTER FM 1K: Integrated load cell in a compact handheld instrument.

SAUTER FM 1K EXT: External load cell connected to a separate display unit.

The integrated version is particularly suitable for direct measurements and compact test stand applications.

The external version is advantageous when the sensor needs to be installed within a dedicated testing fixture.

The decision should therefore be based on the mechanical arrangement rather than the force capacity alone.

Tensile force measurement – Professional pull force testing

Determine extraction, retention and separation forces

Tensile force testing measures the force applied when a component is pulled, stretched or separated.

It is widely used in industrial inspection because many mechanical connections must withstand specified pulling forces.

The SAUTER FM series supports tensile force measurements across a wide range of capacities.

Connector extraction testing

Electrical and mechanical connectors often require defined insertion and extraction characteristics.

A connection with insufficient retention force may separate unintentionally.

An excessively high extraction force may make servicing or assembly difficult.

A digital force gauge can measure the force required to separate a connector under defined test conditions.

Cable retention testing

Suitable cable assemblies and fastening systems can be tested to determine the force necessary to pull a cable or connected element from its fixture.

Appropriate grips and alignment are essential for meaningful results.

Extension spring testing

The tensile force of an extension spring can be measured at a defined extension.

For repeatable results, the spring displacement and testing procedure should remain consistent.

Mechanical latch and closure testing

The force required to release or open a mechanical closure can be evaluated using a suitable force gauge and fixture.

This is relevant for product development and industrial component inspection.

Plastic snap-fit connections

Plastic clips and snap-fit assemblies can be tested to determine their separation or release forces.

Such measurements help engineers compare component designs and manufacturing conditions.

Compression force measurement – Professional push force testing

Evaluate actuation forces, spring loads and mechanical resistance

Compression testing measures forces applied when a component is pushed, compressed or mechanically loaded.

SAUTER FM digital force gauges support a broad range of compression testing applications.

Push-button actuation force

The force required to operate a push button can affect both functional reliability and user experience.

Measuring this force helps verify whether a component meets the intended specification.

Compression spring testing

Compression springs can be tested at defined displacement positions.

A suitable test stand is recommended when consistent loading conditions are important.

Mechanical assembly inspection

Components and assemblies can be evaluated under controlled compression loads.

The test may focus on actuation force, mechanical resistance or another specified performance characteristic.

Plastic component testing

Plastic parts can be subjected to controlled compression to evaluate their mechanical behaviour.

Suitable contact attachments and fixtures help distribute the load correctly.

Peak Hold function – Capture maximum force values

Essential for extraction, breakaway and maximum-load testing

In many industrial applications, the highest force reached during a test is the most important result.

The Peak Hold function captures and displays the maximum registered force.

This makes it particularly useful for applications involving short force peaks.

Typical Peak Hold applications

  • Connector extraction force

  • Mechanical latch release force

  • Maximum spring compression force

  • Push-button actuation force

  • Retention force testing

  • Pull-off force inspection

  • Maximum load comparison

Example: Connector pull-out testing

A connector is secured in a suitable testing fixture.

A pulling force is applied until the connection begins to separate.

During the test, the measured force increases and changes.

The Peak Hold function captures the highest recorded value.

This result can then be compared with the specified acceptance criterion.

The reliability of peak capture depends on the measuring system and the dynamics of the testing procedure.

Track mode – Continuous monitoring of applied force

Observe mechanical load changes during testing

In Track mode, the SAUTER FM displays the current force continuously.

This enables operators to monitor changing loads while a specimen is pulled, compressed or actuated.

Track mode is useful for spring testing, component evaluation and engineering experiments.

It provides immediate feedback about the applied force.

However, continuous force display does not automatically mean that a complete force-time or force-displacement curve is recorded.

1,000 Hz measurement frequency – Fast force acquisition

Capture rapidly changing mechanical loads

The SAUTER FM series operates with a measurement frequency of 1,000 Hz.

This corresponds to an internal acquisition frequency of 1,000 measurements per second.

Fast measurement acquisition is valuable in applications where forces change over short time intervals.

Applications benefiting from fast acquisition

  • Mechanical switch actuation

  • Connector release testing

  • Snap-fit mechanism inspection

  • Short-duration peak force measurements

  • Mechanical breakaway testing

  • Functional component inspection

The internal measurement frequency should not be confused with the data transmission rate to an external computer.

Internal memory for up to 500 measurements

Store force readings directly in the instrument

A major advantage of the SAUTER FM series is its integrated measurement memory.

The instrument can store up to 500 measurement values.

This feature is particularly useful when multiple components must be tested in succession.

Instead of recording every value manually, operators can retain readings in the instrument for subsequent processing.

Benefits of internal data storage

  • Store multiple measurement results

  • Support repetitive inspection procedures

  • Reduce manual transcription

  • Facilitate comparison of measured values

  • Prepare data for further evaluation

  • Improve efficiency at quality-control workstations

Example: Production batch inspection

A manufacturer needs to verify the actuation force of a series of mechanical switches.

Each component is tested according to a defined procedure.

The resulting force values are stored in the instrument.

The readings can subsequently be reviewed or transferred for further evaluation.

Internal measurement storage does not, by itself, constitute a complete traceable inspection report.

Additional information such as specimen identification, test conditions and operator details may be required.

USB-C connectivity – Transfer force measurement data

Connect force testing with digital inspection workflows

The SAUTER FM series includes a USB-C interface for data communication with compatible systems.

This enables force measurements to be used beyond the instrument's display.

Depending on the connected equipment and software, measurement values can be transferred for further processing.

Potential applications

  • Transfer readings to compatible computers

  • Support electronic inspection documentation

  • Compare measurement results

  • Process data in suitable software

  • Integrate force measurement into technical workstations

  • Assist with structured quality-control procedures

Understanding data transmission speed

The internal measurement frequency is 1,000 Hz.

The documented data transmission rate to a PC is approximately 25 measurement values per second.

This distinction is important when planning data acquisition or automated testing systems.

The USB-C interface does not imply that every internally acquired measurement is transmitted individually at 1,000 Hz.

PS/2 interface – Additional system connectivity

Connection options for compatible equipment

In addition to USB-C, SAUTER FM force gauges provide a PS/2 interface.

This expands the available options for connecting supported equipment.

Before integrating the instrument into a test stand or other measurement arrangement, the relevant interface specifications and compatibility requirements should be checked.

Programmable tolerance limits – Efficient Pass/Fail inspection

Compare measured forces with defined acceptance criteria

The SAUTER FM series supports upper and lower force limits for tension and compression measurements.

These limits allow operators to evaluate measured values against predefined requirements.

Visual indication assists with interpreting the results.

Example: Push-button quality inspection

A manufacturer specifies an acceptable actuation force range for a mechanical push button.

During inspection, the force is measured using a SAUTER FM instrument.

The measured value is compared with the configured limits.

This helps identify components that fall outside the defined acceptance range.

Benefits for industrial quality assurance

  • Consistent inspection criteria

  • Faster evaluation of results

  • Support for repetitive testing

  • Reduced manual comparison

  • Clearer identification of deviations

  • More efficient quality-control workflows

Acceptance limits must be established according to the applicable product specification and testing method.

Graphical capacity indicator – Monitor the available measuring range

Additional visual guidance during force application

SAUTER FM force gauges feature a graphical capacity indicator.

This shows how much of the available measuring range is currently being used.

The indicator provides a quick visual reference alongside the numerical force reading.

It is particularly helpful when forces increase progressively during a test.

The capacity indicator does not replace the requirement to remain within the specified measuring range.

Backlit and reversible LCD display

Convenient measurement reading in different working positions

The SAUTER FM series features a backlit LCD display with graphical support.

The backlight improves readability in laboratories, workshops and production environments.

The reversible display orientation allows the measurement value to be viewed more conveniently when the instrument is used in different positions.

This is particularly useful for handheld testing and certain test stand configurations.

SAUTER FM with force test stands

Improve repeatability through controlled force application

Manual force testing can be influenced by operator movement, loading speed and alignment.

A suitable force test stand helps establish more consistent conditions.

SAUTER FM models with integrated load cells can be mounted on compatible SAUTER test stands with capacities up to 5 kN.

The maximum capacity of the installed force gauge must always be respected, regardless of the test stand's higher load rating.

Advantages of test stand integration

  • Improved axial loading

  • Reduced operator influence

  • More consistent test conditions

  • Better repeatability

  • Suitable specimen positioning

  • Compatibility with appropriate grips and fixtures

Manual force test stands

Manual test stands are suitable for applications requiring guided force application without motorised movement.

They can provide improved control compared with unrestricted handheld testing.

Motorised force test stands

Motorised test stands may provide more consistent movement during suitable repetitive testing procedures.

The exact combination must be selected according to force capacity, mounting compatibility, travel requirements and test method.

Force-displacement testing

Some applications require measurement of both applied force and specimen displacement.

A complete force-displacement curve requires suitable displacement measurement and data acquisition equipment.

The SAUTER FM force gauge alone should not be treated as a complete force-displacement testing system.

SAUTER FM for industrial quality control

Verify mechanical performance during manufacturing

Many industrial components must operate within specified mechanical force limits.

A connector must provide sufficient retention force.

A push button must require an acceptable actuation force.

A mechanical latch must release under the intended conditions.

SAUTER FM force gauges support the measurement of these characteristics.

Typical quality-control applications

  • Connector extraction testing

  • Push-button actuation testing

  • Spring force verification

  • Mechanical closure inspection

  • Retention force measurement

  • Assembly force evaluation

  • Production batch comparison

  • Functional component testing

Internal data storage, tolerance checking and digital connectivity make the FM series particularly useful for structured inspection procedures.

SAUTER FM for automotive component testing

Test connectors, switches and mechanical assemblies

Automotive manufacturing involves numerous components whose mechanical performance depends on defined forces.

SAUTER FM instruments can support suitable development and quality-control tests.

Typical applications

  • Electrical connector extraction

  • Switch actuation force

  • Mechanical latch testing

  • Retaining clip inspection

  • Spring-loaded mechanisms

  • Plastic snap-fit assemblies

  • Interior control components

  • Mechanical assembly verification

For safety-critical or standardised testing, the complete measurement system must meet the applicable requirements.

SAUTER FM for plastics engineering

Evaluate snap-fit connections and mechanical component behaviour

Plastic components frequently rely on clips, snap-fit mechanisms and mechanical fastening systems.

The forces required to engage, operate or release these connections can be important quality characteristics.

SAUTER FM force gauges can help evaluate these forces under defined conditions.

Typical applications

  • Snap-fit release force measurement

  • Plastic closure testing

  • Connector inspection

  • Mechanical resistance checks

  • Product design comparisons

  • Production quality control

Suitable grips and loading arrangements are essential to avoid misleading results or unintended damage to the specimen.

SAUTER FM for mechanical engineering

Measure forces in components and assemblies

Mechanical engineering laboratories use force measurements to evaluate the performance of mechanisms, fasteners and structural components.

SAUTER FM instruments can support a range of testing applications within their specified capacities.

External load cell models are particularly useful when higher forces or specialised mechanical fixtures are involved.

Typical applications

  • Mechanical connection testing

  • Retention force measurement

  • Spring mechanism evaluation

  • Actuation force testing

  • Assembly inspection

  • Prototype comparison

  • Functional load testing

SAUTER FM for research and product development

Compare designs and investigate mechanical performance

During product development, force measurement provides valuable information about how components respond to applied loads.

Engineers can use defined tests to compare different prototypes, investigate mechanical behaviour and evaluate design changes.

Typical research and development applications

  • Prototype comparison

  • Spring force analysis

  • Mechanical actuation studies

  • Fastening system evaluation

  • Component resistance testing

  • Functional performance checks

  • Engineering experiments

The integrated memory and digital interfaces support further evaluation of measured results.

For advanced dynamic analysis, complete data logging or force-displacement recording, additional equipment may be required.

SAUTER FM for maintenance and technical service

Check mechanical forces during inspection and servicing

Portable force gauges can also be valuable for maintenance and technical service tasks.

They can be used to compare actuation forces, evaluate mechanical mechanisms or check components against established reference values.

Integrated load cell models are particularly convenient for mobile inspection tasks.

External load cell models may be integrated into suitable fixtures when higher loads or different installation arrangements are required.

Exact specifications, supplied accessories and compatibility requirements should be checked for the selected model.

Understanding capacity, resolution and accuracy

Maximum force capacity

The maximum capacity defines the highest force that can be measured within the specified operating range.

For example, the SAUTER FM 100 has a maximum capacity of 100 N.

Display resolution

Display resolution indicates the smallest force increment shown by the instrument.

For the FM 100, this is 0.05 N.

Measurement tolerance

The manufacturer specifies a tolerance of 0.2% of full scale.

For a 100 N capacity instrument, 0.2% corresponds to 0.2 N.

This demonstrates why display resolution and measurement accuracy must not be confused.

Selecting the appropriate capacity

When measuring relatively small forces, selecting an unnecessarily high-capacity instrument may reduce the usefulness of the available display resolution.

The correct model should cover the expected maximum load while providing suitable measurement performance.

Overload protection and safe operation

Protect the load cell against excessive forces

The SAUTER FM series has a manufacturer-specified overload protection rating of 120% of maximum capacity.

This value must not be interpreted as an extension of the normal measuring range.

The rated maximum capacity must be respected during regular operation.

Recommended practices

  • Select the appropriate force capacity

  • Apply loads along the intended measurement axis

  • Avoid lateral forces

  • Use compatible measuring attachments

  • Prevent excessive impact loading

  • Check fixture and load cell compatibility

  • Follow the manufacturer's operating instructions

For external load cell models, the mounting arrangement and the load rating of the complete mechanical assembly must also be considered.

Measuring attachments and accessories

Adapt the force gauge to different test specimens

The correct measuring attachments are essential for reliable force testing.

Tension measurements may require hooks or suitable gripping systems.

Compression testing may require flat, pointed or application-specific contact attachments.

Typical accessories

  • Tension hooks and attachments

  • Compression measuring tips

  • Grips and fixtures

  • Mechanical adapters

  • Compatible test stands

  • Connection accessories

  • Calibration services

  • Suitable measurement evaluation software

Compatibility depends on the selected model, measuring range and mechanical connections.

For external load cell models, the mounting threads and permitted load capacities must be considered.

Calibration and measurement traceability

Maintain confidence in professional force measurements

Regular calibration may be required when force measurements are used for product acceptance, quality assurance or technical documentation.

Calibration compares the instrument's readings with suitable reference forces.

The resulting deviations can be documented.

Factory calibration

Factory calibration may be suitable when documented measurement comparison is required without a specific need for accredited calibration.

Accredited calibration

For applications with more demanding traceability requirements, accredited calibration may be appropriate.

Available calibration services depend on the model, force range and measurement direction.

Calibration versus adjustment

Calibration determines and documents measurement deviations.

Adjustment changes the instrument's measurement behaviour.

These are separate procedures.

Calibration intervals

Appropriate calibration intervals depend on:

  • Frequency of use

  • Applied loads

  • Environmental conditions

  • Internal quality procedures

  • Measurement requirements

  • Previous calibration results

There is no single calibration interval that is appropriate for every application.
