Torque Transducers for Aerospace Hydraulic Pumps and Motors

September 9, 2005, Depew, NY, USA - Rotating torque transducers from the Force/Torque Division of PCB Piezotronics, Inc. (PCB ®), utilize non-contact, rotary transformers for sending excitation voltage to, and receiving measurement signals from, the strain gage instrumented rotating sensor element. The rotary transformer design eliminates the need for replacing worn brushes, as is the case with conventional slip ring type rotating torque sensors.

Because of their unique flange and splined shaft design (conforms to AND 10262 & 20002), the units are an ideal choice for use in torque studies on cantilevered aerospace hydraulic motors and pumps. Other applications include dynamometers for combustion engines, 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. The units feature high torsional stiffness and low rotating inertia. Custom designed units are available for alternate measurement ranges and speeds.
