Abstract:
1. A thermoanalytical sensor comprising: a substrate that can conduct a heat flow between a heat source that is thermally coupled to the substrate and at least one measurement position that is formed on the sensor; and a thermocouple arrangement formed on a substantially planar surface of the substrate to deliver a thermoelectric signal, wherein the thermocouple arrangement comprises: a serial chain of thermocouple junctions that are composed of two different thermocouple materials serially connected to form a thermocouple column, wherein the serial chain of thermocouple junctions extends in an azimuthal direction around a center of the measurement position; at least one interstitial area of the surface is azimuthally confined between a first thermocouple junction closest to the center and two immediately neighboring second thermocouple junctions in the serial chain; wherein the chain comprises a first thermocouple junction connected to a second thermocouple junction of the chain, and a third thermocouple junction connected to a fourth thermocouple junction of the chain, such that the first, second, third, and fourth thermocouple junctions are arranged at different radial distances from the center of the measurement position.
