Non-contact liquid level sensor is applicable to non-metallic containers without direct contact with the liquid, not affected by scale or other impurities. Intelligent liquid level benchmark adjustment and level memory function, liquid level display mode, can achieve multi-point series connection. Electronic circuit structure rather than machinery ensures stable performance, durability and a long service life. High stability, high sensitivity, strong anti-interference ability make sure it 't be affected by electromagnet, special designed to deal with power frequency interference and common mode interference. Compatible with most 24V power adapter. Strong compatibility through a of non-metallic material containers, such as plastic, glass, ceramics etc, with a 20mm induction distance. Suitable for all kinds of curved , arc, cylindrical container or pipeline liquid level detection. Wide voltage range 24V, suitable for connecting circuits and product applications.
