Lquid Level Float Switch

Float type level sensor/switch is made by housed in a fixed pole of reed switches and in the ball float of permanent magnet, the float surround in a fixed pole. When float along with the change of the liquid level rising or falling,the permanent magnets in the float generated magnetic field near or far away from reed switches, which make closed or disconnected,outputing corresponding switch signals. Float and fixed pole made by non-magnetic metal or engineering plastic.
A motorcycle oil level sensor output resistance signal, resistance change between 5 -100  or 20- 200, special LED oil level displays can clearly show that the amount of oil tank.

Float type level sensor/switch can be used for water, gas, diesel,oil and water mixture, printing ink, alcohol and other chemical liquids. Control liquid surface precision can reach ± 3 mm.
