Abstract
A differential thermal analysis sensor consisting of two low-impedance differential thermopiles. Each thermopile consists of a series of thermocouples joined in series, with the measuring junctions of the thermocouples arranged around a uniform temperature measuring region, and the thermoelectric reference junctions of the thermocouples arranged around a uniform temperature thermoelectric reference region. The differential thermal analysis sensor can be used for single-sample heat flux differential thermal analysis measurements, dual-sample heat flux differential thermal analysis measurements, or power compensation differential thermal analysis measurements.
