Unusual measurement tasks for Burster load cells and force sensors 16 November 2021

Ixthus Instrumentation Ltd is a distribution partner with Burster GmbH, the German precision instrument and sensor manufacturer, supplying complete solutions for torque, force, and angle measurement across a wide range of industries.

Amongst a diversity of more conventional measurement applications that include test stands for motor and drive performance evaluation and industrial press monitoring systems, Burster also undertakes more obscure requirements. For instance, its 8661 series torque sensor was recently assigned for use in an interesting task to ensure optimal screw fitting of titanium dental implants whilst a dual range version of the same sensor was used to measure the static and dynamic torques in a test setup for a desk fan. Equally unusual, Burster’s 8417 series load cell helped a bicycle component manufacturer to test the pulling forces of Bowden-type brake cables.

These more unusual applications all demand highly dynamic sensor performance through high resolution/precision measurement with high sampling rates and mechanical durability. The dental implant application measures ultra low torque measurement around 15Ncm to 50Ncm at speeds up to 2,000rpm as part of a strict no compromise surgical procedure. The desk fan evaluation measures bidirectional static and dynamic torque to ensure optimal performance in motor selection and fan design during the development phase of the product. Similarly the Bowden cable transmitted force measurement application helps cable designers ensure best performance for a range of cable diameter and radius of curvature simulated test set-ups.

The 8661 series torque sensor has a 0 ±10 V output signal or optional USB interface for use with Burster’s DigiVision date acquisition PC software which also includes DLL and LabVIEW drivers. Available in several single range models from 0.02Nm up to 1,000Nm as well as dual range versions, the sensor can also be supplied with a 2000-line encoder to provide precise speed feedback as well as angular displacement to 0.09°. The 8417 series miniature cylindrical load cell covers measuring ranges from 10N to 5 k for tension or compression force between its axially mounted metric exterior threads.
