When pressure measuring copper cylinders are used to measure dynamic pressures, variation of working environment temperature will often cause measuring error. To find out rules governing the temperature errors, experiments of dynamic calibration under high low and normal temperatures for three batches of Φ3.5mm×8.75mm copper cylinders have been carried out. According to the experimental data, the law of variation of pressure measuring error was analyzed. The meaning of deriving a unitary temperature correction equation for pressure measuring copper cylinders was clarified. Means of forming the unitary temperature correction equation was discussed, and the correction equation was derived. The feasibility of this equation has been tested and its result was found satisfactory.
