Non-contact signal transmission for same cost as slip-ring types
The Kistler (www.kistler.com) Type 4520A sensor for measuring torque on shafts rotating at up to 10,000 rpm uses frequency modulation to transmit the torque signal from the rotating shaft without contact and convert it into an analogue signal.
This system is considerably more reliable than slip-ring signal transmission which can suffer signal loss due to dirt and wear on the slip-rings. In the past, contactless sensors have been more expensive than slip-ring types but this design costs about the same as inferior slip-ring types.
The sensor has a TTL speed signal at 60 pulses/rev. and an external 100% range check input. Ten units cover the range from 1 to 1,000 Nm, all with standard ±10 V signal output, and 150% overload capacity. Suitable for static and dynamic measurement of torque in assembly, for quality control in production and in laboratory applications. Priced at about £1,500, the Kistler Type 4520A strain gauge torque sensor represents exceptional value for money.
