Liquid Level Sensor Detector 5~12V 5mA Non-contact Liquid Level Sensor Intelligent Water Level Sensor Induction Level Switch. Intelligent non-contact liquid level sensor adopts advanced signal processing technology and high-speed signal processing chip, and it is not influenced by container wall thickness when detecting the liquid level in a sealed container. The liquid level sensor is installed under the container (high level and low level). No need to bore a non-metallic container, easy to install. It can detect liquid level of various toxic substances, acid, alkali, and all kinds of liquid in high-pressure sealed containers. It can be widely used and has no special requirement for liquid medium and material of container. Features: 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 mechanical parts ensures stable performance, durability, and a long service life. High stability, high sensitivity, strong anti-interference ability ensure it is not affected by electromagnetic fields, specially designed to deal with power frequency interference and common mode interference. Compatible with most 5~12V power sources. Strong compatibility through a variety of non-metallic material containers, such as plastic, glass, ceramics, etc., with a 13mm or more induction distance. Testing is accurate and stable and boiling water level can be detected. Liquid, powder, and particles can all be detected. Adjustable sensitivity.
