method for measuring waermeleitfaehigkeitskoeffizienten and sensor with a waermeleitenden element and with a waermeisolierenden element.

摘要

A method for measuring a heat transfer coefficient between a heat transfer element and a fluid comprises a measurment of a calorific value by putting the heat transfer element into the fluid and charging the heat transfer element with electricity. In the present invention, a calorific value of a particular surface of the heat transfer element is regarded as a calorific value of the whole heat transfer element. This is performed with heat-transferably contacting the particular surface of the heat transfer element with the fluid and making a residual surface of the heat transfer element thermally insulating so as to prevent a heat transfer of the residual surface of the heat transfer element.
