Intelligent non-contact liquid level sensor uses advanced signal processing technology and high-speed signal processing chip, and when detecting the liquid level in an airtight container, it is not affected by the thickness of the container wall. The liquid level sensor is installed under the tank (high and low level). No need to drill non-metal container, easy to assemble. It can detect the liquid level of various toxic substances, acids, alkalis and all kinds of liquid in a high pressure airtight container. It can be widely used, and there are no special requirements for liquid medium and container material. Characteristics: The non-contact liquid level sensor is applicable to non-metallic containers without direct contact with the liquid, unaffected by scale or other impurities. Intelligent liquid level control and level memory function, liquid level display mode, can achieve multi-point series connection. The structure of electronic circuits instead of machines ensures stable performance, durability and long service life. High stability, high sensitivity, strong anti-interference ability make it unaffected by the electromagnet, specially designed to deal with power frequency interference and common mode interference. Compatible with most 24V power supplies. Strong compatibility thanks to various containers of non-metallic materials such as plastic, glass, ceramics etc. with an induction distance of 20mm. Suitable for all kinds of curved surfaces, bends, cylindrical containers or pipeline liquid level detection. The voltage is 24V, suitable for connecting various circuits and product application.
