A DYNAMIC PRESSURE CALIBRATION DEVICE USING A PERCUSSION DEVICE

摘要

A dynamic pressure calibration device is provided to correct an error range of a pressure sensor by feeding instant dynamic pressure through rapidly opening a ball valve in a test chamber. A dynamic pressure calibration device using a percussion device includes a pressure tank(100), a head part(200), a ball valve(220), a pressurizing rode(410), a percussion device(600), and a diffraction link part. The pressure tank(100) has a port(110) in order to apply high pressure. The head part(200) includes a test chamber, a pressure sensor(200) for test and a reference pressure sensor(210). The ball valve(220) is nested on the test chamber. The percussion device(600) is installed on the lower part of the pressure tank(100). The diffraction link part is connected between the pressurizing rode(410) and the fluid jack(440).
