Product Description Three-probe cable stainless steel probe inductive liquid level controller Product Features: 1. Electrode-type liquid level controller, using 304 stainless steel electrode rods, plastic encapsulation forming an insulating sleeve, short-circuit protection design to prevent malfunctions caused by moisture on the tank wall or shaft. 2. Electrode-type liquid level sensor works based on the conductivity of water, utilizing the conductive properties of water in the system. 3. When the water level changes, electrodes of different lengths contact or separate from the water surface, causing the circuit to connect or disconnect, thereby sending a signal reflecting the water level change for control. 4. Function: Detects and sends water level signals. 5. Applications: Suitable for solar water tanks, water pumps, water supply pools, water distribution tanks, water treatment systems, wells, and water storage tanks. Specifications: Colors: Red, White, Blue Probe Material: SUS304 Stainless Steel Cable Length: Red: 1.5m (4.9ft), White: 2.5m (8.2ft), Blue: 3.5m (11.4ft) Liquid Level Sensor Heat Resistance: Up to 105°C Rated Voltage: 250V - 380V Maximum Current: Supports up to 10A Notes: 1. The liquid level sensor must be submerged in water to function properly. 2. Do not short-circuit the sensor probe to the common pole during installation or use. 3. If the standard sensor length is insufficient, the user can extend the cable as needed. 4. When extending the cable, please use shielded cable to prevent electromagnetic interference and potential lightning strike damage. Caution: - Please allow 1-3cm error due to manual measurement. - Due to differences in monitors and lighting conditions, the actual product color may differ slightly from the picture.
