Summary

THE CHARACTERISTICS OF 4 COMMERCIAL STRAIN-GAUGE PRESSURE TRANSDUCERS SUITABLE FOR MEASUREMENTS FROM 4.2 TO 293 K WERE DETERMINED IN THE PRESENCE OF MAGNETIC FIELDS UP TO 6 T. THE HIGHEST PRESSURE WAS 3.5 MEGAPASCAL. TESTS SHOWED THAT IF NO CORRECTIONS ARE MADE, UNCERTAINTIES MAY BE UP TO 19% OF THE FULL SCALE. THE TRANSDUCERS MUST BE INDIVIDUALLY CALIBRATED UNDER THE WORKING CONDITIONS: IN THIS WAY THE UNCERTAINTIES IN PRESSURE MEASUREMENTS CAN USUALLY BE KEPT BELOW 1% OF FULL SCALE.
