Low Pressure Diaphragm Gauges
|
|
|
|
|
|
|
|
|

|
|
|
|
Diaphragm gauges consist of a corrugated metal diaphragm which deflects under pressure. When pressure is applied to the diaphragm it's movement is transmitted through a connecting rod to an amplifying lever and gears which operates a pointer. The pointer will then indicate the pressure on a appropriate scaled dial.
