SOLFRUNT ® 4-1/2"
Model 1929 Low Pressure Gauges
DESCRIPTION

SPECIFICATIONS

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.

SIZES: 4-1/2"

t 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
