Plastic liquid level controller
purpose：The float control level switch is a liquid level switch that can regulate the bucket, groove, or well. It can be automatically adjusted, easy to operate, easy to install, safe and reliable, free of maintenance, non-toxic, environmental protection, can be recycled. It is resistant to water and is widely used in water tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, tanks, etc.. Such as the two series controller, a place to put to the water tower, a water pump to control, can prevent the lack of water pump and open air can also damage the pump equipment; with three controller series, a place to put to the water tower, a filter and another is put into the river (wells) at the same time can control two pump equipment.
Installation and wiring method：
Use black and black wires: when the float is below the level, the contact is on. When the float is on the upper level, the contact is blocked.
Use blue and yellow wires: float is in the upper level, and the contacts are connected. When the ball is below the liquid level, the contact is out of order.
First, working principle:The cable float level switch is used to make contact output with micro switch. When the angle above the horizontal plane exceeds the angle of the lift28°The steel ball inside the float level switch will roll to the microswitch or deviate from the microswitch to make the liquid level switchONorOFFContact signal output. The metal cable float level switch uses the mercury switch to make the contact point output. When the liquid level rises and contacts the floating ball, the floating ball is centered with the heavy hammer and changes with the rising angle of the water level. When the angle above the water rises, the angle exceeds the line10°The liquid level switch will be thereONorOFFContact signal output.
Two. Main features:1Use microswitch to make contact output and contact capacity10A/250VACDirect starting motor equipment.
2Rubber cable, good weather resistance, low price, long service life.
3Simple structure, no maintenance, clean water can be used.
