| Product Release - KPFS Pneumatic Float Switch (Patent Pending) |
| We are very proud to announce the latest innovative product development from KENCO. The Model KPFS Pneumatic Float Switch 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 is the reactive component in the snap-acting switch that opens and closes the pneumatic valve.
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 Model KPFS Pneumatic Float Switch can be ordered to have the pneumatic valve open when it senses the liquid level rising (-LR option) or open when it senses the liquid level falling (-LF option). A manual valve actuator is provided to open the valve manually, if desired. |
