PGK Level Controls

Thermoplastic rod with float - Magnets are embedded within the float.  When the float passed the micro switch in the rod, the switch is actuated.  The LA3000 is a simple two switch that is so easy to configure that we normally provide the unit in kit form that allows for last minute field fabrication changes.  The LA2000 is a step further in that it can be supplied with up to 6 level switches and is available in polypropylene and PVDF (Kynar) for high temperature installations.

Similar in design function to the LA3000, the LA2000 is available with your choice of 1 to 6 switches, available in 8 inches to 20-foot lengths. The switches are activated by a float rising and lowering with the fluid. Additional floats and stop collars may be added to hold each switch in a latched position. The switch to terminal block wiring makes wiring to your controller simple. It also allows for your choice of normally open or normally closed positions.

The LA2000 is available in polypropylene or Kynar (PVDF).  Maintenance of the LA2000 is extremely simple since it requires only periodic checks of the float and column for foreign matter buildup. This switch is factory assembled and tested to insure a quality product.pgk2000.jpg (15555 bytes)
