Thermopile
About thermopile device
The thermopile is the name given to a
temperature measuring device which consists of several thermocouples
connected together in series, such that all the reference junctions
are at the same cold temperature and all the hot junctions are exposed
to the temperature being measured. The effect of connecting n
thermocouples together in series is to increase the measurement
sensitivity by a factor of n. A typical thermopile manufactured by
connecting together 25 chromel-constantan thermocouples gives a
measurement resolution of 0.001 °C.
