Electronic water level switch

I. PROFILE:
Fixed the electronic water level switch, give it the voltage(DC5-24V), it will work. No the float, No the Reed, No mechanical action. Long life, stable property, it can be immerged into the water for long time. It can be put to use in the sewageindustrial wastewater^^

II. The theory of work:
Detect the water level by inner electronic sensor, and IC process the signal, when the water reach the action line. IC will output high level(5V-24V) or low level(0V)

III. Parameter:
Voltage: : DC 5V -24V
Power consumption: <1W output: 24V when have water. 0V when no water
Waterproof degree: IP68 temperature: -20~60degree pressure: 0.8MPA
Size: 150*20mm
