A single finish is soldered to the central block and it is open up on the fluid whose pressure will be to be measured; the opposite end is sealed and coupled for the pointer spindle. If the pressure In the tube is greater than the surface pressure, the tube tends to straighten, Consequently turning the pointer. The pressure is Read more a circular
The functional theory of the Original Bourdon tube relies over a C-formed bent tube. For top pressure ranges helical tubes are made use of. A bent tube has a tendency to straighten and get back its circular kind in cross-section when pressurized. This alteration in cross-segment is sort of imperceptible as well as straightening brings about a defle
