1. Performance: The noncontact liquid level switch features intelligent functions for reference adjustment and storage of liquid levels, a display mode for liquid level status, multipoint series control capability, and supports an output interface. With a pure electronic circuit structure and nonmechanical operation, it offers stability and sensitivity. 2. Wide Voltage Range: The noncontact liquid level switch operates within a broad voltage range of 512V, making it compatible with various circuits and product applications. 3. NonContact Design: The switch detects liquid levels without direct contact. Signals penetrate the outer wall of nonmetallic containers and pipes, unaffected by limescale or deposits. The liquid must be conductive, and the container material must be nonmetallic. 4. Package Contents: 1 noncontact liquid level switch (size: 42mm x 17mm) with a 50cm cable.
