Pressure measurement sonde

摘要

A pressure measurement sonde of the type comprising two piezoelectric detectors, one being used for pressure measurements and the other being used as a reference detector. The latter is used to compensate at least partly, the effects due to temperature variations. This sonde includes means for favoring the heat exchanges of said detectors with the surrounding medium and for substantially balancing the heat exchange rates of each of said detectors with the surrounding medium. The sonde is particulary adapted to the carrying out of pressure measurements in oil wells.
