PCB Piezotronics’ New Rotary Torque Sensor System

The rotary torque sensor system from the Force/Torque Division of PCB Piezotronics is designed for automotive driveline and powertrain dynamometers and other torque measurement applications requiring a robust torque transducer. The Torkdisk features a telemetry system consisting of an on-board electronic module that converts torque signals into a high-speed 16-bit digital output. According to the company’s press release, styles are available that use a non-contact, maintenance-free design that eliminates the need for replacing worn brushes, as is the case with conventional slip-ring type rotating torque sensors. Applications include dynamometer testing of gasoline and diesel engines, transmissions, transfer cases, differentials and drive shafts. Additional applications include torque studies on pumps, fans and electric motors. Rotary torque sensors are offered in capacities from 0.35 N-m to 25.4 kN-m full scale and maximum speeds to 15,000 rpm.
