Mobile calibra­tion test bench » Calibra­tion of hand-held nutrun­ners and built-in nutrunners

Mobile calibra­tion test bench

Our robust calibra­tion test bench offers the perfect solution for the precise testing and calibra­tion of nutrun­ners with a torque up to 500 Nm.

This test bench offers maximum versa­ti­lity with speci­ally adapted mounting plates for each size and thumb nuts for secure fastening.

Tool clamps ensure additional fixation of the nutrunner. The tightening simulator is attached to the base plate.

The height can be easily adjusted with the handwheel, depen­ding on the confi­gu­ra­tion of the simulator and the instal­la­tion size of the reference measu­ring sensor.

QS box digital measu­ring system

The QS box digital measu­ring system from DSM offers an effec­tive solution for the calibra­tion of nutrunners.

The combi­na­tion of QS box, a suitable torque sensor and the MQS software ensures a compre­hen­sive measu­re­ment procedure.

Each measu­re­ment is carried out on the basis of the infor­ma­tion entered about the measu­ring equip­ment, the nutrunner to be tested and the defined measu­re­ment parame­ters. The software not only conducts measu­re­ments but also serves for displaying the measured values and conduc­ting analyses.

This analysis function enables a thorough evalua­tion of the measu­re­ment results in order to identify any devia­tions or trends and take appro­priate action.

Frequently Asked Questions (FAQ)

1. What is a mobile calibra­tion test bench?

A mobile calibra­tion test bench is a portable system designed to calibrate hand-held and built-in nutrun­ners directly on-site, elimi­na­ting the need to send tools to external laboratories.

2. What are the advan­tages of using a mobile calibra­tion test bench?

It reduces downtime, saves trans­por­ta­tion costs, and allows for calibra­tion under actual working condi­tions, ensuring greater accuracy and efficiency.

3. Which types of nutrun­ners can be calibrated with this bench?

The bench is suitable for calibra­ting various models of hand-held and built-in nutrun­ners, inclu­ding those from the DSM DSH and DS series, with torque ranges up to 500 Nm.

4. How does the calibra­tion process work?

The nutrunner is mounted on the test bench and connected to a torque sensor; the system then measures and compares the output against prede­fined standards to ensure accuracy.

5. Is the mobile calibra­tion test bench compa­tible with third-party tools?

Yes, its modular design and adaptable mounting plates allow for the calibra­tion of nutrun­ners from various manufac­tu­rers, not just DSM products.

6. Can the test bench be integrated into existing produc­tion lines?

Absolutely; its compact and flexible design enables seamless integra­tion into current workflows without signi­fi­cant modifications.

7. What documen­ta­tion is provided after calibration?

A detailed calibra­tion report is generated, documen­ting all measu­re­ments and ensuring tracea­bi­lity in compli­ance with quality manage­ment standards.

8. How often should nutrun­ners be calibrated?

Calibra­tion frequency depends on usage inten­sity and quality requi­re­ments, but a regular schedule—such as annually or after a set number of cycles—is recom­mended to maintain precision.
