Answer / Jay Prakash

Pressure gauges installed on reactors typically have a vented diaphragm, which allows for the safe release of pressure in case of overpressure conditions. The vent line is usually connected to a relief valve or safety device that will open if the pressure inside the gauge reaches a predetermined level.nIf the pressure gauge does not have a direct vent line, it may be designed with an integrated safety system that can release excess pressure internally without requiring an external vent line. This internal safety mechanism may include burst disks or rupture discs that will release pressure when the maximum allowable pressure is reached.
