Sensor Developments’ high-performance, noncontact sensors use IR telemetry to measure rotational torque in dynamometer systems. This particular sensor incorporates a variation on the company’s standard configurations by featuring interconnecting splines on both ends, which offers savings in setup time and axial length by eliminating extra adapters. The 01251 IR torque sensor family can be configured in multiple attachment configurations. Offering high frequency response, high sample rate, and high rotational speed as standard features, the sensors are available in single, dual, and custom flange designs. Sensor Developments also offers a customized version of its noncontact dynamometer sensor used to evaluate powertrain systems.
