Kistler adds two new models to its range of reaction torque sensors

Kistler has just added two models to complete its existing range of piezoelectric reaction torque sensors for manufacturing and testing processes, the Type 9329A coming in at the bottom end of the range and the Type 9389A... at the top.

This family of sensors, which now covers the whole measuring range from ±1, ±10, ±25, ±200 and ±1 000 N•m, is suitable for torques from approx. 0,001 N•m, each sensor offers the possibility of measurements over several decades. This is a major advantage that piezoelectric measurement has over other types of measurement. The sensors are supplied calibrated for 100 % and 10 % of the measuring range. Calibration for additional measuring ranges is available as an option.

The sensors are readily adapted to almost any task configurations. Each end has a flange with four (resp. six) threaded mounting holes and a centering seat for precise coaxial installation. A central hole permits a shaft passage.

Thanks to their high sensitivity, extremely rigid construction and compact dimensions, these sensors have a multitude of uses. This type range is particularly suited to applications in assembly technology (such as monitoring screwdriving processes or checking rotary potentiometers, rotary switches or screw caps). As piezoelectric sensors are immune from fatigue and wear when properly used, their service life is virtually unlimited. This means that they are particularly suitable for use as calibration sensors, as well as for general torque measurement in research and development.
