Absolute pressure gauge SOLFRUNT® 1929

analogthreadedstainless steel

The SOLFRUNT 1929 low-pressure process gauge has 316L SST wetted parts, including a diaphragm capsule for measuring low water pressure, from vacuum to 30" H2O through 0 to 200" H2O. The PET case is a solid front design for safety protection, with an accuracy of ± 1% of span (Grade 1A). Dials are available in inches of H2O or psi, or metric versions. The Model 1929 pressure gauge is available in the low mount ¼" or ½" NPT process connection. The pointer is knife edge to allow for precious readings of the pressure. Ranges: Vacuum -60 to 0 "H2O VAC (counterclockwise rotation) Compound -60 "H2O VAC to 60 "H2O These gauges handle pressure measurements as low as a few inches of water; the meters utilize a unique sensing element that spans from 30" H2O to 10 psi. It contains a stack of diaphragm capsules, each consisting of two plates contoured into a convex/concave configuration to nest into one another. This results in a low internal volume element developing large forces to drive the mechanism in extremely low-pressure ranges. The measuring element may be filled and attached to a Mansfield & Green diaphragm seal (Type L) to permit the use of the gauge with corrosive or viscous fluids. Type ST diaphragm seals may also work on Model 1929. Calibration adjustments (scale shape and linearity) are performed from the rear of the case without removing the internals. The pointer is adjusted by removing the front ring and window.
