PSB-100-R87 Pressure Switch (05754428-R87)
PSB-100-R87 Direct Mount Pressure Switch- Set at Rising to 87 PSI (05754428-R87)
The PSB switch is a direct-mount switch for critical pressure points.
It has one limit contact that can be used to activate an alarm, actuate indicator lights or shutdown equipment.
The construction of this instrument is the same as Murphy’s time proven Swichgage® instrument. A precision machined brass mounting plate and port captures a high-quality, stamped beryllium copper diaphragm.
The single-pole, double-throw (SPDT) snap-switch is operated directly from the diaphragm for quick acting and positive switching. Trip point is factory preset according to your specifications. Housing is weather sealed to prevent entry of moisture, dust, etc.
A glass-filled nylon terminal block with screw terminal connections gives the PSB switch a real advantage in industrial engine applications. The PSB is ideal when reading is not desired, but pressure is critical to operational efficiency. Intended for use in general purpose non-classified areas.
