Linear displacement sensor is designed to control movement of various objects, goods elevator cabs, hydraulic lifts in the loading system, etc., that is, in systems that require accurate information on the status of the object during its motion. By way of removing the information of linear displacement sensors are divided into contact and contactless. In turn, divided into proximity sensors with mobile mechanical parts and do not have. Optical and infrared sensors of linear displacements are non-contact and have no mechanical moving parts. Inductive and magnetic sensors of linear displacements are non-contact, but with mechanical moving parts. By contact is resistive sensor. The main characteristic of all types of sensors is to determine the absolute position, movement and speed. To obtain Information from sensors is used RS-485 interface.
Maximum cable length by which one can transmit a signal up to 500 meters Operating temperature -40 C to +60 C. Measured path length from 1 mm to 5000 mm (or 10 000 mm). Individual attention deserves a special series of non-contact electronic sensors Start Electron.com (SE Series) designed for hydraulic mechanisms, where the sensor is operating in harsh conditions with environmental stresses. K advantages of these sensors are: high accuracy of measurement of the distance measured by the protection system from external influences, including vibration; ease of use, a high degree of dust and moisture protection the point when power is off, long service life – due to non-contact measurement method, a high linearity, repeatability and resolution;
