Receiver Gauges
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
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.

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.
