Optical rotary torque sensor with self-diagnostics for status report

 They replace the company's E200 ORT series with a "significant" increase in resolution, frequency response, reduced sensor current consumption, and faster digital data throughput. The electronics are not fixed to the shaft, and the company says it can increase speed, while non-contact operation ensures a long and reliable life. The sensor has a lifetime warranty. The company says that the principle of optics also ensures noise immunity. The 230 series sensors provide fixed voltage or current analog outputs-one for torque and the other for speed or power. The 240 series offers two user-selectable voltage or current analog outputs- one for torque, and the other for speed, power or peak torque- as well as digital outputs including RS232, CANbus, and USB for use with modern instruments and notebooks Computer interface. Up to 10 sensors can be connected via USB. The sensor configuration software can be used to change sensor variables. Features of both sensor families include self-diagnostics that report whether the sensor's torque, rated speed, or calibration date has been exceeded, and built-in sensors monitor shaft temperature for better compensation and accuracy. The device also provides a simple "sensor status" output. TorqView software is a torque monitoring software package for Windows PCs. It provides real-time charting capabilities and is compatible with Matlab and Excel. NationalInstruments LabVIEW VI
