New description: [New technology field] This case is related to a kind of pressure detection system, especially a pressure detection system with fine adjustment and stability. This [Prior Art] The pressure sensor is used to measure the pressure intensity of a gas or liquid. When the operation is repeated, the pressure is converted into a light output. That is to say, the altimeter is an important tool that is indispensable for altitude and altitude. The pressure sensor is the most important component in the altimeter, so that the value of the air pressure can be used to measure the elevation of the altitude. Therefore, the accuracy of the pressure sensor pressure change is a major factor in the height gauge. As shown in Figure 1, it is a block diagram of a conventional air pressure detection system. The system includes a control center 10 'a gas storage tank 20 , a stress test station 4 〇. The gas storage tank 2 is connected to the pressure test station 4 having the sealable chamber 401 by the pipeline circuit 30, and the pipeline loop 30 is provided with a -first solenoid valve 301, a programmable digital pressure valve 3Q2, such as a proportional pressure. The valve and the second solenoid valve 3〇3, the first and second solenoid valves 3〇1 and 303 and the pressure valve 3〇2 are respectively connected to the digital output/interface 102 of the control center 1 . To perform a pressure test on the measured object, such as a pressure sensor, first input a target air pressure value, for example, 6 〇〇 mb, to the controller 101 of the center 10, and then the air reservoir 20 with the vacuum pump 201. After pumping the aforementioned air pressure value, the chamber 401 accommodating the object to be tested is closed, and then the first and second solenoid valves 3〇1, 3〇3 are opened, so that the air in the air reservoir 20 passes through the pressure valve 3. After the high-speed opening and closing operation of the 〇2, and quickly entering the sealed chamber 402, the first and second electromagnetic valves 3〇1, 3〇3 are immediately closed, and the chamber 401 is detected by a pressure gauge 4〇2. The actual barometric pressure value is displayed on the controller 101, such as a computer screen, via the digital/analog conversion interface 彳〇3 via the detected chamber 4〇1 actual air pressure value. Finally, the test object is tested in the chamber by a test instrument. Since the proportional pressure valve 302 has an error value of about ± 〇 5% RS (± 5 mb) and cannot provide a more precise air pressure adjustment function, this will cause the measured object, such as a pressure sensor, to detect a change in air pressure. The accuracy also produces errors. Therefore, only by improving the pressure error value of the aforementioned pressure detecting system can the accuracy of the test object be improved. [New content] The main purpose of this case is to provide a pressure detection system that uses the fine-tuning regulator to control and provide accurate pressure values in the closed pipeline circuit of the pressure detection system, thereby increasing the accuracy of the measured object during detection. . The effect of the gain in this case is to further connect the closed pipeline circuit of the pressure detecting system - the pressure adapter 'the pressure adapter _ wave on the ear principle, by the action of the moving mechanism, the piston in the gas pressure regulator is relatively After the position changes, and the volume change in the regulator is changed, the pressure is generated on the closed pipeline loop.

The piston in the gas pressure regulator also changes position relative to each other, and causes a volume change in the gas pressure regulator to further generate a pressure change, and finely control and provide an accurate target gas pressure value in the closed loop of the force detection.
