Torque sensor revs up to 50,000 rpm and has two ranges

It is available in fourteen measuring ranges from 0.2-20Nm with a rated speed of 50,000rpm and 50-5000Nm at 30,000rpm, all with an integrated speed sensor output of up to 360 pulses per revolution. Both analogue and digital outputs are provided by the integral, digital signal conditioning system making the new sensors suitable for use in laboratory, development, production or quality assurance applications.

The option of two, switchable ranges, with the second range being either 1:10 or 1:5 of the rated torque, allows very precise measurement of both peak and operating torque with the one sensor. In applications with a high peak but moderate operating torque, a sensor with only one measuring range would have to be chosen to withstand the peak torque. As a result, it would be oversized for accurately measuring the lower operating torque.

Contactless power and signal transmission between the rotating shaft and the stator, combined with precision manufacturing, low production tolerances and high grade shaft balancing, essential for reliable, high-speed operation, ensure that the sensors maintain calibration over a long life.
