Ultrasonic level switch UZS-5

Signallers are designed for signalling of liquid level limit values in one or several control points and are used in automatic process control systems, systems for signalling technological and emergency liquid levels, pump protection systems, including at nuclear power facilities. The signallers are designed for operation in conditions of high and low pressures, high and low temperatures, vibration and shock, aggressive and hazardous media, salt fog, frost and dew, electromagnetic interference, special factors. The principle of operation of signalling devices is based on different properties of ultrasound propagation in liquid and gas. The signallers have no moving parts and do not create acoustic interference.
