The SOLFRUNT 1929 low pressure process gauge has 316L SST wetted parts, including a diaghragm capsule for measruring very low inches of water pressure, from vacuum to 30” H2O through 0 to 200” H2O. The PET case is a solid front design for safety protection, with accuarcy of ± 1% of span (Grade 1A). Dials are avialbe 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.
Wetted Parts: 316 Stainless Steel
Ranges: Vacuum - 60 to 0 "H2O VAC (counterclockwise rotation)
Compound - 60 "H2O VAC to 60 "H2O
Designed for pressure measurements as low as a few inches of water, these gauges, in spans from 30" H2O to 10 psi utilize a unique sensing element. It is composed of 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 use of the gauge with corrosive or viscous fluids. Type ST diaphragm seals may also work on Model 1929. Please contact factory for further information.Calibration adjustments (scale shape and linearity) are made from rear of case without removing internals. The pointer is adjusted by removing the front ring and window
