Bourdon tube differential pressure gauge
Budenberg
BOURDON TUBE TYPE :
The Model 179 Differential Pressure Gauge consists
essentially of two opposing bourdon tubes, each having its
own connection but operating a common pointer that shows
the difference between the two pressures.
Used in applications that require an instrument to measure
the difference between two pressures where the system
pressure is up to 4x greater than the differential range.
