置。[Scope of Claim for Utility Model Registration] A lower limit pressure detection means provided in a gas pressure regulator that converts high pressure gas into gas at a predetermined pressure and supplies the gas, and detects a lower limit pressure for gas supply; and upper limit pressure detection means for detecting the gas supply upper limit pressure and occlusion pressure, and checking the supply pressure based on the output signals of the lower limit pressure detection means and the upper limit pressure detection means when the gas is in use,
and a check means for checking the occlusion pressure based on the output signal of the upper limit pressure detecting means when the gas is not in use, and an abnormality detecting device for detecting an abnormality in the gas pressure regulator, the lower limit pressure detecting means and the upper limit pressure detecting means. A detection signal generation means is provided for generating a detection signal when the output signal from the pressure detection means continues for a predetermined period of time, and the checking means detects the supply pressure and the closing pressure based on the detection signal from the detection signal generation means. An abnormality detection device for a gas pressure regulator, characterized by performing a check.
