The portable external load cell torque tester is designed to perform torsion tests directly on components, screws, shafts, couplings and mechanical parts. The display unit is separate from the sensor, making it easier to position the load cell at the test point while keeping the reading visible without interfering with the sample.
Unlike bench torque testers intended mainly for torque wrenches, this instrument is designed primarily to check the torsional behaviour of the component itself. It can be used in laboratories, production departments and testing activities when it is necessary to measure the torque required to tighten, loosen, rotate or bring a component to failure.
The range includes different capacities up to 10 Nm. The measuring range should be selected according to the maximum expected torque and the values to be checked, avoiding the use of a sensor that is excessively oversized for the application.
The external sensor is fitted with an adjustable chuck that can hold compatible bits, adaptors or components directly. Phillips, hex, slotted and other suitable drive bits can be used to adapt the system to the screw head, nut or component being tested.
For correct measurement, the sensor and sample must be aligned along the axis of rotation. One part of the system must also be supported or secured firmly so that torque is transmitted to the load cell without lateral movement, bending or angular misalignment that could affect the result.
The torque tester measures in both clockwise and anticlockwise directions. It can therefore be used for tightening and loosening tests, to check the torque required to start rotation or to detect the maximum value reached while the component is being twisted.
Continuous reading allows torque variation to be observed while the load is applied, whereas the peak function keeps the maximum value reached visible. The first-peak mode is useful when the test requires the first slip, failure, detachment or significant change in the component’s torsional behaviour to be identified.
Minimum and maximum limits can be set to compare the result with a predefined range, supporting pass/fail checks.
The display can show numerical data or a graphical representation. The direction indicator makes it possible to identify immediately whether torque has been applied clockwise or anticlockwise.
Internal memory allows multiple values to be stored and organised into groups, simplifying the management of results from different samples, batches, test sessions or configurations.
Software and connection cable are included. Stored values can be transferred to a computer for archiving and export, maintaining an organised record of the checks performed.
When the torque tester is connected to a PC during the test, the software acquires values in real time and generates the torque/time curve. The graph allows the full torque trend to be observed, the peak value to be identified and any variations before loosening, movement or failure of the component to be analysed.
The software also allows data and graph images to be exported, average and peak values to be calculated over the entire recording or a selected section, and recording start and stop conditions to be set. The torque/time curve is generated only during real-time acquisition.
The portable configuration makes it easy to move the unit between different inspection stations. For recurring tests, or when the sensor and sample need to be supported and aligned consistently, the system can be integrated with a test stand suitable for the application.

FAQ – Portable external load cell torque tester
What is a portable digital torque tester used for?
It is used to measure torque applied to components, screws, shafts, couplings and other parts during tightening, loosening or torsion tests.
What is the difference compared with a torque tester for torque wrenches?
The portable torque tester is designed mainly to check torque directly on the component. SABTE and SABTEX bench models are intended primarily for testing and in-house calibration of torque wrenches and torque screwdrivers.
Why is the sensor separate from the display unit?
The external load cell can be positioned close to the sample, while the display remains in a convenient position for reading and managing the test.
What is the chuck on the sensor used for?
It holds compatible bits, adaptors or components, creating the connection required to transmit torque to the load cell.
Which bits can be used?
Depending on the application, Phillips, hex, slotted or other suitable bits can be fitted according to the component being checked.
Can the torque tester measure screw tightening torque?
Yes. With the appropriate bit, it can measure the torque applied while tightening.
Can loosening torque also be checked?
Yes. The instrument measures in both directions and can detect the torque required to start or complete loosening.
Does the torque tester measure both clockwise and anticlockwise?
Yes. The display also indicates the direction in which torque has been applied.
Which measuring ranges are available?
The range includes different capacities up to 10 Nm, to be selected according to the maximum expected torque and the values to be checked.
How should the correct measuring range be selected?
The capacity should be higher than the maximum expected value, without being excessively wide in relation to the torque values normally measured.
Why is alignment important?
Correct alignment transfers torque along the rotation axis, limiting bending and lateral loads that could affect the result or apply unintended stress to the load cell.
Which measurement modes are available?
The instrument provides continuous reading, peak, first peak and preset-limit modes.
What is the peak mode used for?
It keeps the maximum torque value reached during the test visible.
When is first-peak mode useful?
It is useful for identifying the first slip, failure, detachment or significant torque change while the component is being twisted.
Can acceptance limits be set?
Yes. A minimum and maximum limit can be set to support pass/fail checks.
Does the torque tester have internal memory?
Yes. It can store multiple values and organise them into groups.
Are the software and connection cable included?
Yes. Both are included as standard.
Can stored values be transferred to a PC?
Yes. Measurements stored in the instrument can be downloaded and exported for subsequent management.
Can the test curve be acquired?
Yes. When the instrument is connected to a computer during the test, the software generates the torque/time curve in real time.
What is the difference between memory download and real-time acquisition?
Memory download transfers individual values already saved in the instrument. Real-time acquisition records the continuous torque trend and generates the graph.
Which functions are available in the software?
The software acquires the curve, exports data and graphs, calculates average and peak values, and analyses a selected part of the recording.
Is a calibration report available?
Yes. A calibration report is available on request.
