High-speed torque testing sensor
Kistler designed the Type 4503A torque sensor 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 to 5,000Nm.
Additional benefits are two, switchable ranges, with the second range 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 option of two switchable ranges allows precise measurement of both peak and operating torque with the same sensor. In applications with a high peak, but moderate operating torque, a sensor with only one measuring range would have to be selected to withstand the peak torque which would compromise measurement accuracy at the lower operating torque.
