structural principle |
|
|
Structure: Diaphragm pressure gauge consists of four parts: diaphragm parts, movement parts, pointer parts and shell connection parts.
Principle: Diaphragm pressure gauge is diaphragm as the strong element of the instrument, when the pressure of the measured medium acts on the diaphragm, the diaphragm produces a displacement, and then through the movement parts, pointer parts work, so that the pressure to be measured clearly indicated on the dial.
