179 Differential Gauge

179 Differential Pressure Gauge Budenberg Australia @ Procon Instrument Technology

Bourdon Tude Differential Pressure Gauge

The Budenberg model 179 Differential Pressure Gauge consists essentially of two opposing bourdon tubes, each tube having its own connection but operating a common pointer that shows the difference between the two pressures.

It is ideal for use 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.

Thos differential pressure gauge is designed to withstand full working pressure, applied separately to either connection or together. The maximum working pressure should not be exceeded even temporarily, so the possibility of surging pressures should be considered when selecting the instrument.

These instruments can also be supplied with a central zero scale if necessary, e.g. 1 to 0 to 1 bar (corresponding to a differential pressure range of 2 bar in the table below).

The Budenberg Differential Gauges can be used for a number of applications including:

  1. Calibration of pressure gauges, transducers and transmitters.
  2. Calibration of pneumatic controllers, valves etc.
  3. Measurement of pressure on test beds in Aero, hydraulic systems, diesel engine injection systems.
  4. Setting of pressure relief valves.
  5. Measurement of pore water pressure in soil mechanics laboratories.
  6. Efficiency testing of steam turbines in power stations, gas turbines and compressors.
