The present invention relates to a pressure sensor test device where an inner space (12) is formed with heat-resistance and chill-resistance material for protecting various components installed at inside in a thermo-hygrostat. A mounting lever (18) for mounting a pressure sensor (17) is comprised at the outer surface of a housing (10). A pressure chamber (14) is formed at the inside of the housing and a pressure supplying part (16) interconnects the pressure chamber (14) and the outer part of the housing (10). The pressure sensor (17) is mounted at the pressure supplying part (16) and receives pressure provided at the pressure chamber (14). A second buffer tank (30) is installed at the inside of the housing (10) and an intake and exhaust solenoid valve (34), which is delivering the compressed air of the second buffer tank (30) to the pressure chamber (14) at once through multiple cycles, is installed at the inside of the housing (10). An air generator (24) and a first buffer tank (28) generating the compressed air are formed at the outside of the housing (10) and at the outside of the thermo-hygrostat. According to the present invention, multiple pressure sensors (17) can be tested simultaneously through multiple times, more particularly test pressure can always be uniformly maintained by properly arranging a first buffer tank (28) and a second buffer tank (30). |
