It adopts anti-short circuit design, and not cause malfunction due to moisture or conductivity of water tank or well wall. The conductivity of water in boiler is used, when the water level in boiler Electrode type water level controller adopts electrode rod to form an insulating sleeve with plastic. The change occurs, because the electrode rods of different lengths and different water levels contact and separate, the electrical circuit is closed or opened, and the signal of the reaction water level change is transmitted outward, and then the signal can be further processed according to the signal, the electrode type water level The sensor uses the conductivity of water as the working principle, the sensing quality is stable, it is not easy to generate false signals, and the signal of the position in the water can be reliably received and transmitted., Weight: 1.34261517558 pounds, Manufacturer: Awwertse
