II Differential Pressure Gage
has a clean design, small size, low cost and sufcient
accuracy for all but the most demanding applications.
With housing molded from mineral- and glass-lled
nylon and a lens molded from polycarbonate, this gage
will withstand rough use and exposure, as well as high
total pressure up to 30 psig (2.067 bar). Over-pressure
is accommodated by a blow-out membrane molded in
conjunction with the diaphragm.
INSTALLATION
1. Select a location free from excessive vibration 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 excessive
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 specied when ordering.
Use only with air or compatible non-
corrosive gases.
