The structure of Ordinary Pressure Gauge

Press the dial. To visually read data, a circular disk with several pressure unit scales is frequently used in conjunction with a pointer.
A hint. The dial that shows the pressure reading is fixed above and is linked to the sector gear chain.
Bourdon tube. The C-shaped or spiral metal tube serves as the foundation for monitoring pressure changes by converting the recorded pressure into deformation inside the Bourdon tube.
last component. the Bourdon tube's free end that is attached to the transmission mechanism. The maximum displacement is produced by the free end of the Bourdon tube when its internal pressure varies.
Link. It attaches the free end of the Bourdon tube to the pointer mechanism, allowing the pointer to rotate in response to even slight deformation of the tube. Rack and sector gear. The rack amplifies linear motion and transforms it into rotating motion of the pointer by meshing with the sector gear and connecting to the free end of the Bourdon tube.
Stem with pressure connector. It permits pressure to be transferred from the connection point to the Bourdon tube, supports the connection joint, and connects the pressure gauge to the pressure source.

Principle of Operation

Schematic illustration of the pressure gauge's operation with annotations

As the pressure within the Bourdon tube increases due to the pressure from the tested system passing through the pressure gauge's interface, the wall of the tube will undergo deformation. The pointing mechanism is typically attached to one closed end of the Bourdon tube. Its closed end will cause displacement as the Bourdon tube deforms. By means of a mechanical linkage system that includes a sector gear and a rack, the displacement is transformed into the rotational motion of the pointer. The pointer indicates the pressure within the Bourdon tube by pointing to a particular figure on the dial.
