Electrode type water level controller adopts electrode rod to form an insulating sleeve with plastic.It adopts anti-short circuit design, and will not cause malfunction due to moisture or conductivity of water tank or wall.The conductivity of water in boiler is used, when the water level in boilerThe 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 levelThe sensor uses the conductivity of water as the working principle, the sensing quality is stable, it is not easy to generate signals, and the signal of the position in the water can be reliably received and transmitted.The structure is simple and the service life is long. It can be used for long-term use and is not easy to corrode and fall off, and it can effectively resist the surface scaling problem.The maintenance is simple and easy.1: The level sensor must be placed in the water to measure the water level. It is forbidden to directly measure the sensor and the common pole.2: When the standard liquid level sensor is not long enough, the can extend the wiring by himself.In order to avoid the controller failure, the of the extension cable should be a shielded conductor to prevent damage.: PlumbingProduct name: water level sensorProduct features: high temperature 105 degreesScope of application: solar energy, air can. hot nozzlecolour: White + red + blueMaterial: ABS+stainless steelsize: 1.5m,2.5m,3.5mPackage Contents:3* Water level controller
