Details

The Type 8661 torque sensor operates on the strain gage principle and features non-contact, maintenance-free operation due to its inductive and optical signal transmission methods. This advanced design allows for the direct digitization of signals on the shaft, which are then output as either a voltage signal or via USB by the integrated evaluation electronics. The sensor's superior bearing quality supports operational speeds of up to 25,000 rpm based on the measurement range.

Equipped with a bidirectional voltage output of -10 V to +10 V, the Type 8661 efficiently determines rotation direction. It offers optional enhancements for detailed speed and angle measurements, capable of accommodating up to 2000 increments for precise motion analysis, outputting through a TTL signal.

The sensor is fully compatible with the DigiVision Light software when utilized with USB connectivity, facilitating straightforward integration into diverse control systems. For broader application support, downloadable drivers for LabVIEW and DASYLab are available, enhancing the sensor's versatility in complex setups. Optional accessories such as various lengths of connection cables, metal bellows couplings, and mounting blocks allow for tailored integration into specific customer systems.
