Speed Monitoring

Speed monitoring systems compare revolutions per minute or speed against acceptable rates. These systems vary in complexity, from simple systems that detect slow-downs or stoppages, to more sophisticated systems that warn of deviations from precise tolerances.

speed monitoring


Various offerings for applications such as bearing, gear box, and motor temperature monitoring sensors. These sensors communicate accurate temperatures to the system controls.



These devices display rate, time in process, product sum, ratio, or total counting. They are field adjustable and highly programmable, with setpoint and start delay functions. Available with multiple relay and analog output options.



Position monitoring sensors are used in plant operations to provide feedback of the position of a slide gate or any device where precise movement is required from an absolute encoder.
