  Thermopile  \Ther"mo*pile\,  n.  [Thermo-  +  pile  a  heap.]  (Physics) 
  An  instrument  of  extreme  sensibility,  used  to  determine 
  slight  differences  and  degrees  of  heat.  It  is  composed  of

  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.
