ABSTRACT:
A pressure meter includes a casing, a semiconductor pressure sensor disposed in the casing, a passage for introducing a fluid under pressure to the pressure sensor, a display mounted on one side of the casing for displaying a fluid pressure, and a control circuit for picking up the fluid pressure sensed by the semiconductor pressure sensor as an electric signal, for converting the electric signal to a digital signal, and for displaying the digital signal as a digital value on the display.
