| Abstract: | Calibration of Pirani Vacuum Transmitter was investigated. In the article, the function relationship between the output signal of Pirani Vacuum Transmitter and the vacuum value was analyzed and the relation between the signal indication error and the relative error of the vacuum value was drawn. A calibration apparatus was built and a type of Pirani Vacuum Transmitter was tested by the apparatus. The expanded uncertainty of measurement is 0.046V(k=2) and the relative error of the vacuum value according to t... |
