Rotating torque transducers are CE marked to EMC Directive
PCB Piezotronics has received CE qualifications for its Series 4100 and 4200 rotating torque transducers, in accordance with European Union EMC directives. Sensors use non-contact, rotary transformers for sending excitation voltage to, and receiving measurement signals from, the rotating strain gauge 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 a suitable choice for use in engine and chassis dynamometers, fuel pumps, hydraulic pumps, drive shafts, transmissions, fans, and electric motors. Specially designed units are available for aerospace hydraulic pumps and motor, with flanges and shafts conforming to AND 10262, 20002 specifications.
Series 4100 and 4200 rotating torque sensors offer capacities from 50in-oz to 100,000in-lb (0.35-11.3kNm) full scale and maximum speeds to 15,000rpm. 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.
