Dwyer Series PG Gas Pressure/Differential Pressure Switch
PGW-7200-804-P1
Product Introduction
The Dwyer Series PG Gas Pressure/Differential Pressure Switch is
engineered with a large sensitive diaphragm and a time-tested
mechanical design, ensuring reliable pressure monitoring for air
and compatible gases. Featuring excellent ±1% full-scale
repeatability, it offers precise control with a clear, easy-to-read
scale and convenient external setpoint adjustment. Designed for
application flexibility, the switch supports various
configurations—including SPST, SPDT, DPST, and DPDT—with options to
trigger on increasing pressure, vacuum, or differential pressure.
The PG series is ideal for industrial environments, offering manual
reset functions (on PR/PRL models) and durable switch types
(mercury or hermetically sealed snap switches) to suit different
operational needs.
Product Features
