Torkdisc rotary sensor system is a compact in-line rotary torque sensor for spindle qualification testing of machining centers and other torque measurement applications that require a robust torque transducer where axial space is limited. Sensor helps select proper spindle sizes by comparing rated power to actual torque delivered to cutting tools. Features include high torsional stiffness and low sensitivity to axial and thrust bending moments. Telemetry system consists of an on-board electronic module that converts torque signals to high-speed digital representation. Data are then transmitted to a non-contact pick-up loop without risk of noise or corruption. Remote receiver unit converts the digital data to high-level analog output voltage, frequency output, and a serial digital output. Series offers capacities from 2,000 to 225,000 lb-in. (226 to 25.4 kN-m) full-scale, and maximum speeds to 15,000 rpm. www.pcb.com PCB Piezotronics Inc.
