Tensile force measurement – Professional pull force testing

Determine the force required to pull, separate or extract components

Tensile force measurement is one of the principal applications of a digital force gauge.

It measures the pulling force applied to a component, connection or mechanical assembly.

Depending on the testing procedure, the result can help determine how much force is required to extract, separate or displace a component.

Typical tensile force testing applications

Connector extraction testing

Evaluate the force required to separate suitable electrical or mechanical connectors.

Cable retention testing

Check the pull-out force of appropriate cable connections and fastening systems.

Extension spring testing

Measure the tensile load applied to springs during extension.

Mechanical closure testing

Determine the force required to release or open mechanical fastening mechanisms.

Plastic assembly testing

Evaluate the separation force of snap-fit components and other plastic connections.

Product development

Compare different component designs using defined force-testing procedures.

Reliable tensile measurements require suitable grips, correct alignment and appropriate loading conditions.

Compression force measurement – Accurate push force testing

Evaluate actuation forces, spring loads and mechanical resistance

The SAUTER FE series can also measure compression forces.

This capability is especially valuable when testing switches, push buttons, compression springs and mechanical assemblies.

Common compression testing applications

• Push-button actuation force measurement

• Mechanical switch testing

• Compression spring evaluation

• Mechanical resistance testing

• Product assembly inspection

• Closure mechanism testing

• Component compression checks

• Engineering prototype evaluation

During compression testing, force should be applied as closely as possible along the instrument's measurement axis.

Appropriate attachments and fixtures help improve repeatability and reduce unwanted side loading.

Peak Hold function – Capture maximum force values

Essential for extraction, breakaway and maximum-load testing

In many industrial applications, the most important result is not the current force but the highest force reached during a test.

The Peak Hold function records and displays the maximum measured force.

This makes it particularly useful for applications in which the peak load is the principal acceptance criterion.

Example: Connector extraction force

A mechanical connector is secured in a suitable testing fixture.

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

During the procedure, the force changes continuously.

The Peak Hold function captures the highest registered value.

The operator can then compare this result with the required inspection specification.

Benefits of Peak Hold measurement

• Capture maximum tensile forces

• Capture maximum compression forces

• Evaluate connector extraction loads

• Check mechanical release forces

• Support repetitive quality-control procedures

• Compare results from different product batches

The peak force captured depends on the measurement system's response and the dynamics of the testing process.

Track mode – Monitor force continuously

Observe changes in applied force during a test

In Track mode, the SAUTER FE displays the current measured force continuously.

This allows operators to observe changes in force while a component is being pulled, compressed or actuated.

Track mode is useful for spring testing, mechanical resistance checks and development experiments.

It provides immediate visual feedback during the test.

However, a continuously updated display should not be confused with a complete recorded force–displacement curve.

Pass/Fail testing – Efficient tolerance checking

Evaluate components against predefined force limits

The SAUTER FE series includes a Pass/Fail function with configurable upper and lower limits.

This enables operators to compare measured force values against specified acceptance criteria.

Visual and audible indications support efficient inspection workflows.

Example: Push-button actuation testing

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

During production inspection, the button is tested with a suitable SAUTER FE force gauge.

The measured force is compared with the configured limits.

This helps operators identify components that do not meet the specified requirements.

Benefits for industrial quality control

• Faster evaluation of test results

• Support for consistent inspection procedures

• Clear indication of tolerance conditions

• Reduced need for manual comparison

• Suitable for repetitive component testing

Acceptance limits should always be established according to the applicable product specification or testing procedure.

1,000 Hz measurement frequency – Fast force acquisition

Capture rapidly changing mechanical loads

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

This corresponds to a measurement acquisition frequency of 1,000 readings per second.

Fast acquisition is valuable in applications where force changes rapidly during a short testing interval.

Typical applications

• Mechanical switch actuation

• Connector release testing

• Snap-fit mechanism inspection

• Short-duration peak force measurements

• Product functionality testing

• Engineering development experiments

The measurement frequency does not, by itself, define the complete dynamic accuracy or the speed of any external data communication.

Backlit and reversible display

Convenient measurement reading in different working positions

The SAUTER FE features a backlit digital display.

It improves readability in different lighting conditions and professional working environments.

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

This is particularly helpful for handheld applications and varying test configurations.

Ergonomic handheld force measurement

Practical operation in production and engineering environments

SAUTER FE force gauges feature an ergonomic housing designed for professional handling.

Their compact dimensions make them suitable for use at inspection benches, engineering workstations and different testing locations.

The instrument measures approximately 71 × 31 × 180 mm and has a net weight of around 350 g.

Handheld force testing provides flexibility, but measurement repeatability can be affected by the operator's movement, loading speed and alignment.

For procedures requiring more consistent conditions, a compatible test stand is recommended.

SAUTER FE with a force test stand

Improve repeatability with controlled force application

The SAUTER FE series can be mounted on compatible SAUTER force test stands with capacities up to 1 kN.

A suitable test stand helps guide the force along a defined axis.

This can reduce operator-related variations and improve consistency during repetitive testing.

Advantages of test stand integration

• Improved axial force application

• More consistent test conditions

• Reduced operator influence

• Better suitability for repetitive inspections

• Compatibility with appropriate grips and fixtures

• Controlled positioning of the test specimen

The correct test stand should be selected according to the required force capacity, movement characteristics and test method.

For force–displacement analysis, additional compatible equipment and measurement capabilities may be necessary.

SAUTER FE for manufacturing quality control

Verify mechanical performance during production

In industrial manufacturing, force measurements can provide valuable information about component performance and assembly quality.

Many products must operate within defined force limits.

A switch may require a specified actuation force.

A connector may need a minimum retention force.

A mechanical closure may have to open within an acceptable force range.

The SAUTER FE series supports these inspection tasks through its measurement ranges, Peak Hold function and tolerance checking capabilities.

Common quality-control applications

• Actuation force testing

• Connector pull-out testing

• Spring force verification

• Mechanical closure inspection

• Assembly force evaluation

• Product batch comparison

• Functional component testing

SAUTER FE for automotive component testing

Evaluate switches, connectors and mechanical assemblies

Automotive component development and manufacturing frequently require mechanical force testing.

The SAUTER FE series can support suitable laboratory and production checks involving:

• Switches and buttons

• Electrical connectors

• Mechanical retaining elements

• Spring-loaded mechanisms

• Plastic snap-fit assemblies

• Interior control components

• Mechanical locking systems

For safety-critical or standardised tests, the complete testing system must meet the relevant requirements.

SAUTER FE for plastics engineering

Evaluate snap-fit connections and mechanical component behaviour

Plastic components often rely on clips, snap-fit connections and mechanical fastening systems.

Their functional performance may depend on defined insertion, extraction or release forces.

Digital force gauges can help engineers compare these forces during product development and quality inspection.

Typical applications

• Snap-fit release force measurement

• Plastic closure testing

• Mechanical connector inspection

• Compression testing of suitable plastic parts

• Product design comparisons

• Repetitive assembly inspection

Suitable grips and loading arrangements are essential to prevent unintended damage or misleading results.

SAUTER FE for research and product development

Compare designs and investigate mechanical performance

Engineering laboratories use force measurements to understand how components respond to applied loads.

During product development, a digital force gauge can help identify differences between prototypes and assess the effects of design modifications.

Typical research and development tasks

• Prototype comparison

• Spring mechanism evaluation

• Mechanical actuation studies

• Component resistance testing

• Product functionality assessment

• Investigation of fastening systems

For advanced automated testing, extensive data logging or full force–displacement analysis, a more comprehensive testing system may be required.

SAUTER FE for maintenance and technical service

Check mechanical forces during inspection and servicing

Portable force gauges can also be valuable in maintenance and technical service environments.

They may be used to compare mechanical actuation forces, check spring-loaded mechanisms or investigate changes in component behaviour.

The compact housing and protective carrying case make the FE series convenient for use at different inspection locations.

Force measurement units – Understanding Newton and other units

What does a force gauge measure?

A force gauge measures an applied mechanical force.

The SI unit of force is the newton (N).

One newton is the force required to accelerate a mass of one kilogram at one metre per second squared.

The SAUTER FE series supports several selectable force units:

• Newton (N)

• Kilonewton (kN)

• Kilogram-force (kgf)

• Ounce-force (ozf)

• Pound-force (lbf)

Newton is the preferred SI unit for technical and engineering measurements.

The availability of additional units can be helpful when working with international testing specifications.

Measurement range, resolution and accuracy

Important specifications when selecting a force gauge

Three technical characteristics should be considered separately.

Maximum measuring capacity

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

Display resolution

The smallest increment shown on the instrument's display.

Measurement tolerance

The permissible measurement deviation specified by the manufacturer under defined conditions.

For the SAUTER FE series, the manufacturer specifies a tolerance of 0.3% of the maximum measuring capacity.

For example, 0.3% of a 100 N full-scale capacity corresponds to 0.3 N.

This demonstrates why a fine display resolution does not automatically indicate an equally small measurement error.

Overload protection and safe operation

Protect the measuring sensor from excessive loads

The manufacturer specifies overload protection of 150% of the maximum measuring capacity.

This should not be interpreted as an extended normal operating range.

Measurements must remain within the instrument's specified capacity.

Excessive loading, impact forces or improper alignment may damage the measuring sensor and compromise measurement performance.

Recommended operating practices

• Select a suitable force capacity

• Apply force along the measurement axis

• Use compatible measuring attachments

• Avoid lateral loading

• Follow the manufacturer's operating instructions

• Inspect equipment regularly

• Use an appropriate test stand when necessary

Measuring attachments and accessories

Adapt the instrument to different force-testing tasks

SAUTER FE force gauges are supplied with standard measuring attachments and a protective carrying case.

Depending on the application, additional fixtures, grips or test stands may be required.

Tensile force measurements may require suitable hooks or gripping systems.

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

All accessories must be mechanically compatible and rated for the expected forces.

Calibration and measurement traceability

Maintain confidence in professional force measurements

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

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

The required calibration interval depends on the application, operating conditions and the organisation's quality procedures.

Appropriate calibration services and certificates should be considered when selecting a SAUTER FE model.

Calibration determines and documents measurement deviations; adjustment changes the instrument's measurement behaviour. The two procedures are not interchangeable.

How to choose the right SAUTER FE digital force gauge

Step 1 – Determine the expected force

Identify the maximum tensile or compression force expected during the test.

Include an appropriate margin for possible force peaks.

Step 2 – Select the measuring capacity

Choose the model that covers the required force range without unnecessarily sacrificing useful resolution.

Step 3 – Consider the test method

Determine whether the measurement will be performed manually or with a test stand.

Step 4 – Select suitable attachments

Ensure that the force can be applied correctly to the test specimen.

Step 5 – Define the acceptance criteria

For quality-control applications, establish suitable upper and lower force limits.

Step 6 – Consider calibration requirements

Determine whether the application requires documented calibration or specific traceability.
