Torque sensors for every application


Torque has to be measured in both production and assembly, and again in quality control. Burster – the precision measurement technology specialists – offer a range of sensors for the smallest torques of a few tenths of one Nm such as required for quality assurance of rotary switches, all the way up to torques of 1 000 Nm for testing engines

The model 8661 is available, for example, in different sizes, beginning with sensitive measurements of 0 to 0.02 Nm to determine a breakaway or friction torque, and for speeds up to 25 000 rpm. The largest size can measure up to 1 000 Nm which makes it suitable for performance testing of large engines and gearboxes. Common to all measuring ranges is a very low linearity deviation of less than 0.05% of full scale.

Burster also offers solutions for special tasks. These include dual range sensor models with high precision in both measurement ranges. For example, this means that a low steady-state load torque can also be measured with the best possible accuracy on test specimens that have a high starting torque. The robust construction of the sensors and optional features such as tare function or filter and average value settings can open up further applications, including in price-sensitive or difficult conditions.

Burster can carry out individual modifications to both the mechanics and the electronics for be special OEM requirements. A mounting block simplifies alignment so it is easy to change the sensor frequently. The measured values – torque plus angle and speed measurement depending on the model – are output as an analog signal with 0 to 10 V DC or via UBS. The DigiVision software allows up to 1 000 measurements/sec to be read out, displayed graphically and stored.

Alternatively, drivers are available for integration into LabView, DASYLab or proprietary software. With DIGIFORCE process control nits, measurement programs for various processes can be implemented flexibly. All torque sensors can be supplied with DAkkS/WKS calibration certificates.
