Measuring torques cost-effectively, reliably and maintenance free
The measuring specialists at burster have developed an economical torque sensor with an inductive power supply that is also insensitive to EMC interference thanks to optical data transmission. The model 8675 sensor consists of a rotor flange with a DIN hole pattern and a stator (Fig. 1). This supplies the evaluation electronics for the strain gauge in the rotor with energy, receives the measurement data digitised in the rotor via IR LEDs without contact and can transmit torques even when stationary. This eliminates the need for wear-prone contact rings and bearings and the sensor is maintenance free. Depending on the version, the measuring range is 0 to 100 Nm or 0 to 5000 Nm. With an accuracy of 0.2 % or 0.1 % (optional), the sensor is optimised for the vast majority of applications in mechanical or plant engineering, as these can often do without higher precision, but not without reliability, high durability and maintenance free operation. Typical applications can be found in the quality monitoring of electric motors and gearboxes, in test bench construction or in research and development.
Practical sensor for many applications
The extremely compact sensor solution can be easily integrated even in tight spaces. Optical IR transmission also offers an additional benefit for international use: in contrast to radio transmission, no complex authorisation procedures are required for different markets. This reduces costs and shortens delivery times. The torque sensor is sourced as standard with both an analogue output (0-5 V, 0-10 V, ±5 V, ±10 V) and a frequency output (RS422, 24 bit) as well as a USB port for configuration (Fig. 2,3). A test and calibration protocol is included in the scope of delivery, optional standard and special calibration certificates, also with accreditation symbol, are possible via the burster calibration laboratory and can be ordered directly if required. The temperature range is between -20 °C ... +85 °C, the maximum operating torque is 300 % of the nominal torque (Fig. 4).
