Kistler Instruments has introduced the Type 4520A contactless, low maintenance torque sensor at around the same price as slip-ring types, typically less than £1,500. Using non-contact signal transmission eliminates wear, making the new sensor exceptionally robust and maintenance free, even in continuous use.
Ten models are available with rated torque from 1 to 1,000Nm each with class 0.5 accuracy at speeds up to 10,000 rpm. Output is the standard ±10 V plus a speed signal of 60 pulses/rev and a remotely switchable 100% test function.
The new range is suitable for static and dynamic torque measurement in production, quality control and research and development applications.
