Applicable scenarios: The non-contact level switch is suitable for non-metallic containers that are not in direct contact with liquids and are not affected by scale or other impurities, providing a versatile solution for level detection. Fully functional: This level sensor has complete functions such as level memory, level adjustment and level marking, enabling multi-point serial display. It provides great flexibility of use in a variety of scenarios and applications. Stable performance: Thanks to its advanced electronic circuit, this level controller ensures stable performance, durability and long service life. It has high stability, high sensitivity and high interference ability to ensure long-term reliable results. Excellent quality: This liquid level detection tool has high stability, high sensitivity, strong interference and interference ability to ensure that it is not affected by the electromagnet, specially designed to deal with power frequency interference and common mode interference, compatible with most 5~24V power adapters. Accurate measurement: The water level sensor test is accurate and stable, it can detect the level of boiling water. Liquids, powders, particles can all be detected with high compatibility through various non-metallic material containers such as plastic, glass, ceramics, etc., with an induction distance of 13mm or more. Features: 1. The non-contact liquid level sensor is applicable to non-metallic containers without direct contact with liquid, not affected by scale or other impurities. 2. The liquid level and liquid level mark setting and level memory function, liquid level display mode, can realize multi-point series connection. 3.Electronic circuit structure rather than machinery ensures stable performance, durability and long service life. 4.High stability, high sensitivity, strong anti-interference and anti-interference ability, to ensure that it will not be affected by the electromagnet, specially designed to deal with power frequency interference and common mode interference, compatible with most 5~24V power adapters. 5.The test is accurate and stable, and the boiling water level can be detected. Liquid, powder, particles can all be detected, with high compatibility through a variety of non-metallic material containers, such as plastic, glass, ceramics, etc., with an induction distance of 13mm or more. Features: As the picture shows Package includes: 1 x Sensor
