Non Contact Liquid Level Sensor: This sensor designed for use on the exterior of non metallic containers, without direct contact with the inner wall. It is resistant to corrosion from strong acids and alkalis, and unaffected by scale or other debris. It can accurately detect boiling water levels. Stable Performance: The sensor operates using a pure electronic circuit structure, not mechanical, ensuring stable performance and durability. It has high stability, sensitivity, strong anti interference ability and is not affected by external electromagnetic interference. Wide Compatibility: This sensor can penetrate various non metallic containers such as plastic, glass, etc., with a sensing distance of up to 1.5mm; it can detect liquids, powders and granules. High Low Level Output Mode: Suitable for connection with various circuits and product applications; for 5V power adapters available in the market. Product Specifications: Non Contact Liquid Level Sensor made from fire resistant material; dimensions are 26MM in width, 6.1mm in thickness, no space required. Specification: Working current: 5MA Waterproof grade: IP67 Material: Fireproof material Installation method: can be directly pasted on the outer wall of the plastic container or screw Adhesive materials: glass glue, 704 silicone, waterproof double sided tape, etc. Notes: 1. Double sided tape made of foam cotton cannot be used. 2. The container material must be insulating material. 3. Try to use materials with uniform material, no air interlayer, no bubbles, no water absorption, and dielectric constant that is not easy to change as containers. Size Chart: Width: 2.6cm/1.02inch Package Includes: 1x Non Contact Liquid Level Sensor Note: Please allow slightly errors 1-2cm differences due to manual measurement.
