Standard Hastelloy C-276 barrier diaphragm
Adjustable span
Material NACE Standard MR-01-75-compliant
DESCRIPTION
The Moore 50PW3 Pneumatic Pressure Transmitter is
available for measurement of absolute gauge or differential
pressure. The instrument is a “force-balance”
device with built-in overrange protection to the maximum
working pressure. The zero adjustment is accessible
from the outside of the cover. The coarse and fine span
adjustments that provide the means for changing calibration
are accessible from under the cover.
The output signal is 3-15 psig or 20-100 kPa ga and is
directly proportional to the measured process pressure.
When specified a Supression-Elevation Kit which mounts
under the cover can also be supplied. This kit allows adjustment
of supressed-zero or elevated-zero ranges.
A pipe mounting bracket is furnished to attach the instrument
to a 2 inch vertical or horizontal pipe.
