For the security of the Turbine we have a special panel
called TSI ( Turbine supervisory instrument)panel. We
install more then 75 instrument (RTD , Thermocouple ,
Pressure switch, pressure Gauge, Pressure transmitter , and
most importantly we use VIBRATION PROBE , SPEED SENSOR , KEY
PHASER , DIFFERENTIAL EXPANSION PROBE, LVDT(for CASING
EXPANSION),Eccentricity probe ). And all these instruments
are terminated in this TSI panel.

Why does a pressure gauge installed on reactor, doesn't have any vent line below to release the pressure? Is it any kind of designing mistake or it actually does not require any vent line? And if it does not require any vent line below it then how we are gonna release the pressure built inside the pressure gauge?
