Definitions for "Thermopile"
A set of thermocouple junctions connected in series in order to boost the voltage to a meaningful amount (usually measured in millivolts). A thermocouple is a metallic strip or wire that produces an electromagnetic potential (voltage) when the two ends (junctions) are at different temperatures. The "cold" junctions of thermopile radiometers are painted white to reflect radiation, and the "hot" junctions are painted black to absorb radiation.
an array of usually series connected thermocouples designed to increase to signal level and or provide a degree of spatial temperature averaging.
a group of thermcoouple s connected in series
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.
Heat sensitive generator that triggers the on/off switch without an additional electrical source (allows operation of the appliance when the lights go off). It is an integral component of safety valves on heater-rated gas appliances.
