PURPOSE: A pressure gauge is provided to monitor a process by directly detecting a change of pressure in a site even though power supply is stopped and reduce an installation cost by mounting the pressure meter at a time. CONSTITUTION: A pressure gauge includes a socket(1) communicating with a fluid pipe(20) for transferring fluid pressure, a bourdon tube(16) mounted on the socket and changing the position according to fluid pressure, a movement(17) converting the change of position of the bourdon tube, a pressure sensor(3) mounted inside a pressure sensor hole(2) formed at a side of the socket, an amplifier(6) for amplifying detection signal output from the pressure sensor, and a connector(8) for transferring electric signal output from the amplifier to an external system. The pressure sensor detects fluid pressure flown into the bourdon tube and generates electric signal.
