Value for Money Rotating Torque Sensor has Wireless Signal Transmission

The Basic Line Torque Sensor from Kistler Instruments (Type 4520A Torque Sensor) uses FM wireless technology to transmit the signal from the rotating shaft and so eliminates the signal distortion and loss inherent in slip-ring sensors.

The maintenance free, long term reliability advantages of the contactless signal transmission do not come at a premium price but at around the same cost as slip-ring types.The Kistler Type 4520A, a strain gauge torque sensor for use at speeds up to 10,000 rpm (ten thousand rpm), is available in ten ranges from 1 to 1,000 Nm all with ±10 V analogue signal output, a TTL speed signal at 60 pulses/rev, an overload capacity of 150% and an external 100% range check input are all standard. The high frequency response and robust anodized aluminium body giving IP40 protection makes the Type 4520A ideal for static and dynamic measurement of rotating torque in assembly and quality control in production and for R & D applications in the laboratory.
