DWYER DIFFERENTIAL PRESSURE GAGES

Service: Air and non-combustible,
compatible gases (natural gas option
available). Note: May be used with
hydrogen. Order a Buna-N diaphragm.
Pressures must be less than 35 psi.
Wetted Materials: Consult factory.
Housing: Die cast aluminum case and
bezel, with acrylic cover. Exterior finish
is coated gray to withstand 168 hour salt
spray corrosion test.
Accuracy: ±2% (-HA model ±1) of
FS (±3% (-HA ±1.5%) on -0, -100PA,
-125PA, -10MM and ±4% (-HA ±2%) on
-00, -60PA, -6MM ranges), throughout
range at 70°F (21.1°C).
Pressure Limits: -20 in Hg to 15 psig
(-0.677 to 1.034 bar); MP option: 35 psig
(2.41 bar); HP option: 80 psig (5.52 bar).
Enclosure Rating: IP67.
Overpressure: Relief plug opens
at approximately 25 psig (1.72 bar),
standard gages only.u
