Specifications
All Marsh Bellofram General Purpose Gauges are manufactured to strict
ASME B40.1 specifications.
-
Accuracy: 3-2-3%, 2% of range across middle half of scale.
-
Temperature limit: Ambient temperature and temperature of the operating
medium should not exceed 160°F (71°c). Install a protective syphon
when used on steam. Minimum temperature at -40°F (-40°c)
-
Bourdon Tube/Socket: Vacuum, compound and pressure ranges 600 PSI
and below utilize a phosphor bronze bourdon tube. Pressure ranges 1000
PSI and above use a copper alloy helical bourdon tube. All ranges are soft
soldered to the brass socket and tip.
-
Movement: Brass for 1½" gauges. Other sizes utilize a brass
sector and pinion with polycarbonate side plates.
