Torque Measurement

Solutions

To connect strain gauges to a measurement system, the signal needs to be adjusted. Therefore the matching strain gauge  measuring amplifier needs to be used. It provides a constant supply voltage and collects and enhances even the smallest signal change of the strain gauge. BMC Messsysteme Gmbh has to offer two different measuring amplifiers. The MAL-SG2 respectively MAL-SG5 enables a particularly cost effective and simple implementation. The MA-UNI offers a galvanic isolation, various measuring ranges, switchable filters and a simple offset-/gain-correction. Both amplifiers deliver a output signal of +/- 5 volt, which matches the measuring systems of BMC Messsysteme GmbH in the most perfect way.

With the miniature measurement amplifiers of the MAL-Series it is very easy to connect from your sensors to the measurement systems of BMC Messsysteme GmbH. With our 5B compatible measurement amplifiers these signals can even be galvanically isolated from the measurement system.

Torque signals usually change rather slow. It is a huge challenge to acquire torque signals in rotating shafts. Therefore special sensors with abrasive rings or contact free transmission have to be used. Most of the time it is not possible to reach high prescision results.

Torque transducers are sensors that define the torque by measuring the shape change of a measuring body – the so called bellow. Most torque sensors work with strain gauges. Strain gauges are measuring devices for the acquisition of expanding and compressing deformations. They change their electric resistance within the slightest deformation and are used as strain sensors. They have to be applied on components with special adhesive that deform under minimal stress. This deformation (strain) results in a change of the resistance of the strain gauge. Bridge circuits are often used when measuring with strain gauges. This includes mainly quarter-, half- and full-bridges. Strain gauges come in various material versions, like foil-, wire- and semi-conductor strain gauges as well as multiple strain gauges in various assembly forms like strain gauges with lateral extension, full-bridge strain gauges and rosette strain gauges.
