Series 4115K rotary torque transducers from PCB Piezotronics, Aerospace & Defense Div., Depew, NY, use noncontact rotary transformers for sending excitation voltage to, and receiving measurement signals from, the strain-gauge-instrumented rotating sensor element. The sensors' flange and splined shaft design conforms to AND 10262 and 20002 making them suited for torque studies on aerospace hydraulic motors and pumps. Features include a torque output signal, high torsional stiffness, and low rotating inertia. An optional pickup provides an output proportional to speed. Other applications include dynamometers, drive shafts, transmissions, fans, and electric motors.
