Maintenance Free Torque Transducers

Depew, New York, USA -Rotating torque transducers from the Force/Torque Division of PCB Piezotronics, Inc. utilize non-contact, rotary transformers for sending excitation voltage to, and receiving measurement signals from, the rotating strain gage sensor. The maintenance-free, rotary transformer design eliminates the need for replacing worn brushes, as is the case with conventional slip ring type rotating torque sensors. The units are an ideal choice for use in dynamometers and in torque studies on fuel pumps, hydraulic motors and pumps, combustion engines, drive shafts, transmissions, fans, and electric motors.

The standard Series 4100 rotary transformer torque sensors offer capacities from 50 in-oz to 100,000 in-lb (0.35 to 11.3k N-m) full scale and maximum speeds to 20,000 rpm. In addition to the torque output signal, an optional pickup provides an output proportional to speed. The units feature high torsional stiffness and are available with keyed shaft, spline shaft, or flange ends. Custom designed units are available for alternate measurement ranges and speeds.
