ultrasonic probes for use in harsh environments.

摘要

ULTRASOUND DEVICE TO DETECT OR MERGER OF SOLID POSITIONS OF CONTACT SURFACES SOLID / LIQUID LIQUID MEDIA, ESPECIALLY FLUIDS PROCESS OF BAYER. Said device comprising at least one piezoelectric element provided with electrodes; ELECTRICAL CIRCUIT ELEMENTS CONNECTED TO TRANSPORT said electrodes, when connected electrical signals from and to a recording equipment; A INDOW ultrasonically transparent, MADE OF CARBON VITREO, located adjacent the or each of the piezoelectric elements; A protective matrix, preferably epoxy resin, INCLUDING SURROUNDING the or each piezo AND ELECTRODES, ALLOWING SIMULTANEOUSLY THE PASSAGE OF ULTRASOUND WAVES THROUGH THE WINDOW OF EACH WINDOW OR, TO OR FROM EACH piezo; AND EXTERNAL ENCLOSURE, preferably it comprising alkali resistant elastomer Caustic and having a surface nonporous LISA, forming the exterior of the device, EXCEPT IN THE AREA OR WINDOWS. COAL UTILIZATION IN SUCH VITREO windows makes PROBES are resistant to corrosion and oxidation, without hindering the effectiveness of the device. SE provides greater resistance to oxidation using an elastomeric material, preferably used AS EXTERNAL ENCLOSURE.
