Abstract: The use of electronic pressure calibrators in the gas industry has added new concerns and issues in pressure measurement. With the onset of electronics, new and strange words began appearing. Readings and terms appeared that perhaps didnt match the old reliable standby calibration readings or methods. Terms like sensitivity, accuracy, resolution, stability, and traceability surfaced. Technicians began using correction factors to achieve standard conditions. These correction calculations gave the technicians challenges when performing their calibrations. Technicians began seeing the effects of temperature on their test instruments and how temperature effects the accuracy of the gas measurement. This paper will look at the selection and use of electronic pressure calibration equipment. Technicians will find that these instruments will make their job easier if they look carefully for instruments that are traceable, precise, accurate, sensitive, and repeatable. The American Petroleum Institute Chapter 21, offers good advice and recommendations for selecting electronic instruments.
