The principle and characteristics of cable ball float liquid level switch1

The working principle,

cable ball float liquid level switch is use a micro switch for contact output. When the water level rose to more than 28 ° line Angle, internal steel ball will roll the ball float liquid level switch to the micro switch or from the micro switch, make the liquid level switch ON or OFF the contact signal output. Metal cable ball float liquid level switch is made contact output using mercury switch, when the ball float liquid level rise contact, floating ball changing with water level rise Angle for the center with a heavy hammer. When the water rose to line Angle more than 10 °, liquid level switch will have ON or OFF the contact signal output.

2, main features:

1, the use of micro switch contact output, 10 a250vac contact capacity can be directly starting motor equipment.

2, rubber cable, weather resistance, low price, long service life.

3, simple structure, and does not need maintenance, can use sewage purification.

4, the length of the cable ≦ 20 meters, all can be customized.
