THERMOPILE
Ther"mo*pile, n. Etym: [Thermo- + pile a heap.] (Physics)
Definition: An instrument of extreme sensibility, used to determine slight
differences and degrees of heat. It is composed of alternate bars of
antimony and bismuth, or any two metals having different capacities
for the conduction of heat, connected with an astatic galvanometer,
which is very sensibly affected by the electric current induced in
the system of bars when exposed even to the feeblest degrees of heat.
