Thermopile
</dt>
1. A transducer
for converting thermal energy
directly into electrical
energy, composed of pairs of thermocouples
which are connected either in series or in parallel. See Moll
thermopile, Eppley
pyrheliometer.

2. A battery of thermocouples connected in series to form a single compact
unit. The output voltage of N pairs of series-connected thermocouples is N
time the voltage developed by a single pair, whereas the current developed by
N pairs of parallel-connected thermocouples is N times the current developed
by a single pair. Thermopiles are used in thermoelectric radiation instruments
when the output of a single pair of thermocouples is not large enough.
