Manufactured in Polyphenylene Sulphide (PPS) for corrosion resistance in most liquids, the 003 range of ultrasonic liquid level switches can be mounted in any position in a tank using either a 25mm/1" or 19mm/¾" thread available in BSPP, BSPT and NPT thread forms. A thread is provided on each side of a hexagonal boss to allow either external or internal / pole mounting of the sensor. Comprising a one piece moulded body with an integral pcb, the 003 switch is factory sealed and supplied with a 3m/10ft flying lead for customer connection.

The Mobrey 003 ultrasonic liquid level switch is designed for high or low level alarm duties to give a voltage free contact or solid state transistor output for alarm signalling or as part of a pump control system.

The 003 ultrasonic sensor may be mounted at any angle in the vessel.
