An investigation of quartz type pressure transducer behavior under continuous pressure conditions and metrological characterization

In this work the behavior of high accurate quartz based pressure transducer under the continuous pressure conditions was investigated and metrologically characterized. Paroscientific digiquartz pressure transducer which belongs to the pressure laboratory of INRIM was chosen as a device. First measurements were realized in INRIM and UME in 2005. Two different measurement procedures were applied. The pressure was applied at each pressure points approximately during 25 min to observe the behavior of transducer under applied continuous pressure conditions. The results of standard calibration procedure were compared with the results of applied continuous conditions procedure. The same measurements were repeated in INRIM and UME in 2010 to compare the results taken from 2005 to 2010 and the long term stability was evaluated.

► We investigated the behaviour of high accurate quartz based pressure transducer. ► It was metrologically characterize under the continuous pressure conditions. ► The results of standard calibration were compared with continuous conditions. ► The stabilities of transducers having full scale 7 and 100 MPa were examined.
