Feature:1. WORK DETAIL: When the liquid level of the container is abnormal, the alarm signal from the liquid level sensor is triggered to control the water pump to adjust the water level.2. SENSITIVITY ADJUSTABLE: You can adjust the sensitivity. Remove the plastic cover of the controller, turn the very small screw, reduce the sensitivity clockwise, and increase the sensitivity counterclockwise.3. EASY INSTALLATION: Installation is simple and convenient. The water level controller can be installed by screw positioning or electric box track.4. ABS MATERIAL: Made of premium ABS material, the liquid level controller is wear resistant and impact resistant, ensures long term sensitive work.5. WIDE APPLICATION: Relay dry node output, which can be used for various load control, such as filling or emptying oil tank.Specification:Item Type: Water Level Controller Material: ABSWorking Current: Working current less than or equal to 110mA, static current consumption less than or equal to 20mALoad Power:Resistive load is less than 1.6KW (overload or three phase load requires additional AC contactor)Inductive load below 1KW (overload or three phase load requires additional AC contactor) Inductive load refers to the load with inductive coil, such as motor, electromagnet, solenoid valve, etc.Alarm Output: 800W (resistive load) normally open, normally closed outputOutput Mode: Normally open, normally closed outputInput Signal: Induction signal inputWorking Temperature: - 20 to 105 Overall Size: Approx. 115 x 90 x 40mm / 4.53 x 3.54 x 1.57in .Package List:1 x Water Level Controller1 x Screwdriver
