This water level detector controller is adopt a diffusion silicon chip to encapsulate the diffusion silicone oil-filled core in a stainless steel housing. The front end protective cap can be used as a protective sensor diaphragm, and also allows the liquid to smoothly contact the diaphragm. Equipped with 4 bits digital LED display, you can see the datas clearly. Widely used in water plants, sewage treatments plants, urban water supply, high-rise pools, wells, mines, industrial pools, water tanks, oil pools, hydrogeology, reservoirs, rivers, oceans and other places. You can have a try. Features: Uses a diffusion silicon chip to encapsulate the diffusion silicone oil-filled core in a stainless steel housing. The front end protective cap can be used as a protective sensor diaphragm, and also allows the liquid to smoothly contact the diaphragm. The wire and housing are sealed and connected, the ventpipe is connected to the outside in the cable. The internal structure is designed to prevents condensation. Built-in micro signal processing circuit can be used for remote transmission with fine stability and reliability. Equipped with 4 bits digital LED display, you can see the datas clearly. Widely used in water plants, sewage treatments plants, urban water supply, high-rise pools, wells, mines, industrial pools, water tanks, oil pools, hydrogeology, reservoirs, rivers, oceans and other places.
