MODEL KEFS LIQUID LEVEL FLOAT SWITCH

INSTALLATION / OPERATION INSTRUCTIONS

PRINCIPLE OF OPERATION

The Model KEFS uses a float to determine the presence or absence of liquid at the process connection. The float arm assembly

consists of a float at one end and a magnet at the other. As the level rises, the float rises, and the magnet falls. The magnet

actuates a second magnet on the other side of the pressure boundary. This second magnet causes the switch to change state.

The pressure boundary contains no seals; it is a solid stainless steel barrier that passes a magnetic field, but no liquids. It is

impossible for the process liquid to enter the switch enclosure through this barrier.

The electrical contacts consist of a microswitch that can be either a Single-pole, Double-throw (SPDT) or Double-pole, Double-throw

(DPDT) Configuration. The SPDT Switch is available with either a 5 Amp or 8 Amp current load. The DPDT is available with a 5

Amp/30Vdc current load (See Switch Types and Ratings in the Product Specifications for more details).
