Three Probe Cables Stainless Steel Probe Induction Sensor for Water Tank Liquid Level Controller Feature: 1. Electrode type water level controller, using 304 stainless steel electrode pole, using plastic encapsulation to form an insulating sleeve, using anti-short circuit design, not because of the water tank or shaft wall damp conduction caused by misoperation. 2. The electrode water level sensor takes the conductivity of water as its working principle, and makes use of the conductivity of the water in the boiler. 3. When the water level in the boiler changes, the electric circuit is closed or disconnected because of the contact and separation between the electrode poles of different lengths and the water at different water levels, thus the signal reflecting the change of the water level is transmitted to the outside, and then according to this signal, the water level can be changed. 4. Function: receiving and transmitting the signal in the location of the water. 5. Application: Solar air tank, water pump, water supply pool, distribution pool, water treatment pool, well, water tank. Specification: Color: red, white, blue Probe material: SUS304 stainless steel. Length: red wire: 1.5 meters or 4.9ft, white wire: 2.5 meters or 8.2ft, blue wire: 3.5 meters or 11.4ft. Liquid level sensor: heat resistance 105 Product voltage: 250V-380V Product current: maximum support 10A pass Warm Tips: 1. The liquid level sensor must be placed in the water to measure the water level. 2. It is forbidden to measure the sensor and the common pole short circuit directly. 3. When the standard liquid level sensor is not long enough, the user can extend the wiring by himself. 4. In order to avoid the controller failure, the extension wire should be shielded to prevent the interference of thunder damage. Note: Please allow 1-3cm differs due to manual measurement.
