The new type 4503A torque sensor from Kistler Instruments is designed to meet the demands of testing at high speeds in both production quality control and development. Typical applications include testing of electric motors, generators, drive performance, measurement of transmission or spindle drive friction, at a manual workstation or in networked, automated production cells.
They are available in 14 measuring ranges from 0.2 to 20Nm with a rated speed of 50,000rpm and 50 to 5,000Nm 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 laboratory, development, production or quality assurance applications.
The option of two, switchable ranges, 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.
