Stainless steel electrode pole with plastic encapsulation for insulation and anti-short circuit design, preventing misoperation due to damp conduction. Operates on the principle of water conductivity, effectively monitoring water levels in applications. The electric circuit is activated or deactivated based on the contact and separation of electrode poles at different water levels, providing accurate water level signals. Versatile application in solar air tanks, water pumps, supply pools, distribution pools, water treatment pools, , and water tanks. High heat resistance up to 105, supporting a product voltage range of 250V-380V and a maximum current of 10A. Voltage: 300V This electrode type water level controller is designed for reliable and efficient monitoring of water levels in environments. Its stainless steel construction ensures durability, while the insulated design prevents misoperation. The sensor's functionality is based on the conductivity of water, allowing it to accurately detect changes in water levels. With a range of applications, including solar air tanks and water treatment pools, this product is ideal for both residential and industrial use. The long wire lengths provide flexibility in installation, making it a practical choice for diverse setups.
