PCB unveils Series 4115K rotary torque transducers

-- Test & Measurement World, 10/1/2009 2:00:00 AM

PCB Aerospace & Defense has introduced the Series 4115K rotary torque transducers for use in torque studies on aircraft turbine engine air starters and cantilevered aerospace hydraulic motors as well as in automotive applications such as dynamometers, drive shafts, transmissions, fans, and electric motors. The new transducers use noncontact, rotary transformers to send excitation voltage to, and receive measurement signals from, the strain-gage instrumented rotating sensor element.

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. PCB says these units feature high torsional stiffness and low rotating inertia. Models are available with several measurement ranges and speeds up to 27,000 rpm.
