1/2 NPT Thread Type Water Level Float Switch:
(1)Fast fitting
(2)No standby power requirement
(3)Customer can define activated distance,cable length and connector
(4)Wide operation temperature:-40~+200oC
(5)Suit to tough environment and long life
(6)Widely used in liquid level control, air conditoning system and industrial process control
Working Theory:
When the float ball rises or falls with the liquid to the level of the switch, The magnetic force of magnet which inside of the float ball will cause the reed switch to turn ON. When the float ball move away from the reed switch, the reed switch will turn OFF.
