Negative gauge pressure comparison: range -95 kPa to 95 kPa (EURAMET Project 1131).

Popis výsledku v původním jazyce

A pressure comparison in the negative gauge pressure range was arranged in 2009. The participating laboratories were CMI/Czech Republic, FORCE Technology/Denmark, AS Metrosert/Estonia and MIKES/Finland. Negative gauge pressures are a common range for pressure calibrations although uncertainty requirements are generally not very high. The results from the four participating laboratories suggest that calibrations in the negative gauge pressure range are not as easy as expected. Some of the claimed uncertainties were perhaps too optimistic, and the large variation in the results made it difficult to generate consistent reference values. The agreement of the results at positive gauge pressures on the same transfer standard was much better. Obviously thereis a need for further comparisons in the negative gauge pressure range. The transfer standard was a multifunction calibrator Beamex MC5 equipped with an internal pressure module for the range - 100 kPa to 104 kPa in the gauge mode. The re
