PURPOSE: A pressure measuring device equipped with an over-pressure safety valve is provided to reduce the cost required for constructing a system since an overpressure safety valve function is integrated into a pressure measuring device of a simple construction. CONSTITUTION: A pressure measuring device equipped with an over-pressure safety valve comprises an upper case(100), a lower case(200), and a pressure measurement and safety valve module(300). The upper case forms an upper body. On the upper case, an overpressure outlet(110) opened to outside is formed. The lower case forms a lower body connected to the upper case. On the lower part of the lower case, a hole(230) to which the pressure of the fluid is applied is formed. The pressure measurement and safety valve module is installed in the upper case. The pressure measurement and safety valve module comprises a valve(310) discharging the fluid to the overpressure outlet.
