What is the function of pressure gauge in the boiler? Correct Answer To indicate steam pressure

The function of the pressure gauge is to indicate the steam pressure inside the boiler drum in bar or in Kgf in cm2 or in KN/m2 in gauge pressure. If the boiler is fitted with a superheater, one more pressure gauge fitted to the superheater header indicates the superheated steam pressure at any given instant.
