Description: Intelligent non-contact liquid level sensor uses advanced signal processing technology and a high-speed signal processing chip. It is not affected by the container wall thickness when detecting the liquid level in a sealed container. The liquid level sensor is installed below the container (high and low level). No need to drill a non-metallic container, easy to install. It can detect the liquid level of various toxic substances, acids, alkalis, and all types of liquids in high-pressure sealed containers. It can be widely used and has no special requirements for the liquid medium and container material. Features: Non-contact liquid level sensor is applicable to non-metallic containers without direct contact with the liquid, and is not affected by deposits or other contaminants. Intelligent adjustment of liquid level reference and level memory function, liquid level display mode, can achieve multi-point series connection. Electronic circuit structure instead of mechanics ensures stable performance, durability, and long service life. High stability, high sensitivity, strong anti-interference ability ensures it is not affected by electromagnetism, specially designed to handle power frequency interference and common mode interference. For most 5~24V power adapters. Strong compatibility through a variety of non-metallic material containers, such as plastic, glass, ceramic, etc., with an induction distance of 13mm or more. Testing is accurate and stable, and boiling water level can be detected. Liquids, powders, and particles can all be detected.
