PCB develops rotary torque sensor

A PCB Piezotronics product story
Edited by the Engineeringtalk editorial team Sep 7, 2009

PCB Aerospace and Defense, a division of PCB Piezotronics, has announced a Series 4115K rotary torque transducer.

These transducers use non-contact rotary transformers for sending excitation voltage to, and receiving measurement signals from, the strain gauge instrumented rotating sensor element.

Their flange and splined shaft design, which conforms to AND 10262 and 20002, makes these units suitable for use in torque studies on aircraft turbine engine air starters, cantilevered aerospace hydraulic motors and pumps.

Other applications include automotive applications such as dynamometers, drive shafts, transmissions, fans, and electric motors.

In addition to the torque output signal, an optional pickup provides an output proportional to speed and an optional K-type thermal couple to monitor internal bearing temperature.

These units feature high torsional stiffness and low rotating inertia.

Models are available with several measurement ranges and speeds up to 27,000rpm.
