Diaphragm Sensing Pressure Gauges

Diaphragm Sensing Pressure Gauges are mostly preferred, where pressures are low, thereby eliminating the use of the Bourdon type due to its insensitivity.


In such a assembly, the sensing component is a diaphragm, which is connected to the movement assembly through a ‘Ball & Socket’ arrangement.

The Pressure to be measured is transmitted through this Diaphragm to the transmission shaft.

The diaphragm offers dual advantage in such type of assembly. Along with increased sensitivity for low pressure measurement it also serves as an Isolation between the process medium and the pressure sensing element.
