The non-contact liquid level sensor is suitable for the outer wall of non-metallic containers without direct contact with the liquid. It will not be corroded by strong acids and alkalis and other corrosive liquids, and will not be affected by scale or other debris. Detection is accurate and stable, and boiling water level can be detected. Pure electronic circuit structure, non-mechanical working mode, stable performance and durability. High stability, high sensitivity, strong anti-interference ability, no external electromagnetic interference, special treatment for power frequency interference and common mode interference, to be compatible with all 5~24V power adapters on the market. Strong compatibility, penetrates various non-metallic containers, such as plastic, glass, ceramic and other containers, sensing distance can reach 20mm; liquid, powder and particulate matter can be detected. Open collector output mode, wide voltage range (5~12V), suitable for connecting various circuits and product applications. ----------------------- None ----------------------- 1pc Non-contact Liquid Level Sensor
