Capable of measuring speed and length with a typical accuracy better than +/- 0.05%, µSpeed Smart Sensor is the ideal gauge for replacing contact tachometers which tend to measurement errors caused by slippage, chatter or vibration, dirt build-up and day to day wear problems. The most compact and easy to handle in class µSpeed Smart-sensor uses proven laser doppler technology. Thus it has no moving parts, is maintenance free and permanently calibrated, resulting in significant time and money savings. Being designed for machine integration the Smart-sensor does not use an external processing unit like the standard µSpeed system.
