Features Non-contact induction probe The water level controller adopts non-contact capacitive induction technology and special induction control chip design, the probe is durable, strong anti-interference ability, sensitive induction, no contact with liquid, corrosion resistance, safety, environmental protection and no pollution. Overflow Detection Function: The default wiring is water inlet detection. If you want the overflow detection function. What you need to power the alarm output terminals, terminal C on pump output and C terminal on alarm output should be connected. Then connect them with a wire. Intelligent Control When the liquid level of the container is too low, the low liquid level alarm signal of the low liquid level sensor is triggered to trigger the controller to close the relay to start the water pump to add the liquid level. Easy to install: installation is simple and convenient. The water level controller can be screwed and installed, also can be installed on the rail of the electrical box. 【Wide Voltage Power Supply】Dry contact relay output, the controller can be applied to a variety of loads. With control diversification, the water level controller can control the pump in manual or automatic mode. Specification: Item Type: Automatic Water Level Controller Material: ABS Model No.: XKC C352 3P (Fully Automatic Water Level Control and Inlet or Overflow Detection) Input voltage: 100V AC at 260V, 50 or 60Hz.
