The Bourdon tube developed by Eugene Bourdon in 1849 is still the most common method for mechanical pressure measurement in the oil and gas industry.
The gauges use Bourdon tube sensing elements and do not require any external power sources to operate.
These were based on the principle of barometers and utilised a Bourdon Tube, a hollow metal tube with a sealed distal end.
Furthermore, the pressure at the suction and discharge of the compressor was measured with separate bourdon tube pressure gauges.
Under laboratory test conditions, the 316L stainless steel Sta-Kool cooling element was able to reduce 400DegF (204DegC) liquid process temperatures to 100DegF (38DegC) at the active portion of the Bourdon tube.
A stem allows for a flush surface mount and a welded bourdon tube is standard.
These lower pressures are transmitted to a silicone dampened helical Bourdon tube which is connected directly to the pointer shaft.
As a chamber is evacuated, the diminishing pressure will exert a smaller force differential on a thin-walled diaphragm or closed-end Bourdon tube that will result in motion that is proportional to the pressure differential between the chamber and the ambient atmosphere.
The operation and design of pressure gauges dates back to the mid-1800s when Eugene Bourdon invented the Bourdon tube.
