Intended use
The float level switch B-3 are used to keep between 2 points the level of liquid like water, oil, chemical products, etc., conductive or not, in tanks or recipients at atmospheric pressure.
Function
The B-3 bases their work due to the movement of a float. When the level of liquid rises up, the float reaches the mechanical stop and pull up the rod. This enables the action of the lever and reverses the position of the switch.
The adjustment of the commutation of the switch is obtained adjusting the mechanical stops at the desired rod point. If the float is blocked with the mechanical stops, it can be obtained only one punctual signal.
Mechanical connection
It is simple: the float must be vertically installed on the top of the tank with an appropiate support to fix it or through a M12 hole. The tank can have a cap to preserve the liquid against dust. Just a M12 hole in the cap allows the free movement of the rod.
