  • Publication number: 20190339409
    Abstract: An apparatus for estimating a first property in a borehole penetrating the earth is described. The apparatus includes a carrier configured to be conveyed through the borehole. The apparatus also includes a first sensor disposed at the carrier and configured to perform a first measurement of the first property, the first sensor having a first direction of sensitivity; a second sensor disposed at the carrier and configured to perform a second measurement of a second property, the second sensor having a second direction of sensitivity; and a processor configured to receive the first and second measurements and to correct the first measurement using the second measurement in order to estimate the first property.

  • Patent number: 8046176
    Abstract: A device and a method for determining material moisture by thermogravimetry. Included in the device are: a test chamber (2) delimited by a chamber cover (8); a microwave field that can be generated by a magnetron (5) and supplied to the test chamber by a waveguide (4); a tuning rod (22) arranged in the test chamber; a sample carrier (3) which is operatively connected to a weighing module (6) mounted upstream of the test chamber; and at least one sensor (24) arranged in the test chamber. The tuning rod is arranged centrally on the chamber cover, above the sample carrier, and the at least one sensor is arranged on the free end of the tuning rod, opposing the chamber cover.
