Dwyer PG-153-P1 Series PG Gas Pressure/Differential Pressure Switch

Dwyer PG-153-P1 Series PG Gas Pressure/Differential Pressure Switch,
The Series PG Gas Pressure/Differential Pressure Switch has a large sensitive
diaphragm and a reliable time proven mechanical design. For use with air and other
compatible gases, they feature excellent ±1% of full-scale repeatability, clear easy-to
read scale and convenient external set point adjustment.
Application flexibility is assured by a large variety of switching options including
SPST, SPDT, DPST and DPDT; opening or closing on increasing pressure, vacuum
or differential. PR and PRL models add manual reset operation on increasing
or decreasing pressure. Mercury switches or hermetically sealed snap switches
are available where high humidity would be a problem. If vibration or other factors
preclude the use of mercury, snap switches can be provided. Standard housing is
NEMA 1. Optional enclosures can be supplied for weather resistant and explosion
proof requirements.
