Working Principle

The gauge operates using a Bourdon tube mechanism. When pressure enters the curved tube, it deforms slightly. This movement is transferred through a linkage system, driving the pointer to indicate pressure on the dial.

The liquid filling (glycerin or silicone oil) dampens vibration and ensures stable readings even under pulsation conditions.

Frequently Asked Questions

Why is a liquid filled gauge used?
