Series 2-5000 Minihelic ® II Differential
Pressure Gages have clean design, small
size, low cost and sufficient accuracy for all
but the most demanding applications. With
housing molded from mineral- and glass-filled
nylon and a lens molded from polycarbonate,
this gage will withstand rough use and expo-
sure, as well as high total pressure up to 30
psig [2.067 bar].Over-pressure is accommo-
dated by a blow-out membrane molded in
conjunction with the diaphragm.
INSTALLATION
1. Select a location free from excessive vibra-
tion and where ambient temperature will be
between 20°F to 120°F (-6.7°C to 49°C).
Sensing lines may be any length necessary
without affecting accuracy. However, long
runs of tubing will dampen readings slightly
and cause a minor increase in response time.
If pulsing pressure or vibration cause exces-
sive pointer oscillation, please contact factory
for ways to provide additional damping.
2. This gage is calibrated and zeroed in the
vertical position at the factory. If the gage is
used in any other position, it must be re-
zeroed each time the position is changed.
Gages with ranges under 5 inches w.c.(1.24
kPa), or the equivalent, should be used only in
the vertical position unless special calibration
was specified when ordering.
