Moore 50PW3 Pneumatic Pressure Transmitter FEATURES & BENEFITS Process fluid isolation Standard Hastelloy C-276 barrier diaphragm Adjustable span Material NACE Standard MR-01-75-compliant Pneumatic Products 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.

No span effect. NOTES: (1) Maximum working pressure that will not damage the instrument, modest re-zeroing may be required. (2) The stated performance data on standard transmitters (ones with Hastelloy C diaphragm and trim and Silicone oil fill) is applicable to both zero and non-zero based spans. Other options may decrease the performance to 1.5 times the stated value. (3) Differential version only.
