Calibration experiments carried out in 62 absolute capacitance pressure transmitters using the direct comparison method showed that 53 of them met the purchase specification requirements and 9 presented some kind of failure: 6 due to inaccuracy, 2 to the inability to make the zero adjustment and 1 due to the lack of output signal. Typical values of accuracy, resolution, and dead zone for the accepted transmitters were: 0,2%, 0,02% and 0,04% of full scale (F.S.) respectively.
