Abstract
A sensing unit for a differential scanning calorimeter includes a superposition of layers of a thermoelectric arrangement, a layer of an electrical heater arrangement and a layer of an absolute temperature measurement arrangement. The thermoelectric arrangements, the electrical heater arrangements and the absolute temperature measurement arrangements are symmetrically arranged on a sample-side and a reference-side of the sensor.
Claims9
A sensing unit for a differential scanning calorimeter comprising:
- a disc-like substrate suitable for being mounted in heat conductive contact with a temperature-controlled heat source of said differential scanning calorimeter, said disc-like substrate comprising:
- sample-side and reference-side pan support regions adapted to receive thereon in heat conductive contact therewith a bottom of a sample pan and a reference pan, respectively;
- sample-side and reference-side thermoelectric arrangements for generating between two terminal portions thereof sample-side and reference-side electrical voltage signals, respectively, indicative of flows of heat across sample-side and reference-side measuring regions, respectively;
- and
- sample-side and reference-side electrical heater arrangements beneath said sample-side and reference-side pan support regions, respectively;
- and
- sample-side and reference-side absolute temperature measurement arrangements beneath said sample-side and reference-side pan support regions, respectively.
