The function of pressure switches in boilers

Pressure switches and pressure gauges are used to control and read the pressure in the steam boiler. The reading obtained by the pressure switch is the reference used by the system to control the fuel to be released, seeking to maintain a certain vapor pressure in the system. Two pressure switches are normally used for this application.
