Description:

BPSN4KB25XFSH2 differential pressure and vacuum switches use two different actuators depending on set point require-ments. For set points between 2 and 3000 psi, the simple,rugged diaphragm-sealed piston actuator is used. This design features high reliability and choice of actuator seal materials for virtually every application. An optional welded design is also available forset points up to 1000 psi for maximum reli-ability. This design is available in 316 SS or Monel. Differential pressure models use a unique, dual diaphragm-sealed piston design that features very high static operating pressures and small size. For set points between 4.5 and 150 inches of HO, a large dia-2 phragm is used for increased sensitivity in both pressure and differential pressure designs with good choice of materials of construction.
