Answer / faiyaz ahmad

Controller is device which is used to control the field instrument.
Transmitter is device which is used to measure a physical quantity.

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?
