Optical transducers provide dynamic torque measurement
Sensor Technology
The digital ORT 230/240 Series optical rotary torque sensors (photo) provide precise, dynamic measurement of rotary and static torque of less than 100 Nm, for bandwidths of up to 50 kHz. These new devices replace the company’s E200 ORT Series, and feature advanced electronics that deliver improvements in resolution, frequency response, reduced current consumption and faster digital data throughput, says the manufacturer. Non-contact operation is said to ensure a long, reliable life with high accuracy and noise immunity, and the company offers a lifetime warranty. These sensors include self-diagnostics that report when the transducer’s torque, speed ratings or calibration data have been exceeded. Additional sensors monitor shaft temperature for improved compensation and accuracy. Integral software enables data display and recording. — Sensor Technology Ltd. Banbury, U.K.
