Calorimetric measuring arrangement and calorimetric measuring method

摘要

It is a particularly simple calorimetric measuring arrangement (2) for the determination of the power loss of a magnetic material (60) is proposed. The measuring system comprises a first thermally insulated relative to the surroundings area of the volume (26), of the material (60) contains. The during the application of an alternating voltage is applied to the material (60) to energy losses is released in this case via a heat exchanger (40), which a specific heat capacity of & 1,1 j k^-1g^-1 on a first temperature sensor (20) transmit. As a reference temperature, the temperature of a gas or gas mixture in a second insulated area of the volume (27) which, by means of a second thermal sensor (25) is determined.
