Liquid Level Sensor

Our patented product is different from general solution of liquid level detect. Benefit by using the principle of optoelectronics, there is no moving part in our product. Compact structure, small size. High precision. High reliability, long life. What's morn, we are capable to produce it in a low price but high quality still.
Compare to ultrasonic liquid level sensor :

• Our switch have a small size, compact structure and easy to assemble. Unlike the float type level switch, which needs large space to fit in, and the min liquid level is limit by the depth of immersion of the float ball, which is around ± 3.0mm. Our product is capable to detect the liquid's depth within 0.5mm.
• Our product is capable to place in the every face of the tank, bottom side face top, meanwhile, float type level switch can only place at the bottom or top.
• Friction-free, no moving part, much much higher reliability. Would never stuck like float type level switch does.
• Have a shiny surface, easy to clean.
• Build-in infrared led & photistor, long life.
• Electronic part and liquid detecting part are completely isolated.
• No safety loophole
