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.
Claims8
A device for determining material moisture by thermogravimetry, comprising:
- a test chamber delimited by a chamber cover,
- a magnetron generating a microwave field
- a waveguide supplying the microwave field to the test chamber,
- a tuning rod arranged in the test chamber,
- a sample carrier in operative connection with a weighing module mounted upstream of the test chamber, and
- at least one sensor arranged in the test chamber,
- wherein the tuning rod is arranged at the chamber cover centrally above the sample carrier and wherein the sensor is arranged at a free end of the tuning rod distal from the chamber cover.
