Kistler’s type 4503A torque sensor has been designed to provide a flexible instrument for use at rotational speeds of up to 50,000rpm with a choice of fourteen measuring ranges, from 0.2–5,000Nm, says the company.

Additional benefits are: two switchable ranges, with the second being either 1:10 or 1:5 of the rated torque; integral digital signal conditioning providing both analogue and digital outputs; contactless signal and power transmission; and a speed sensor output of up to 360 pulses per revolution.

The company claims the the sensors maintain calibration over a long life in both laboratory and production environments.
