(Tıp) thermopile
An electronic device that converts thermal energy into electrical energy. Usually constructed using a series-combination of thermocouples
a kind of thermometer for measuring heat radiation; consists of several thermocouple junctions in series
A transducer for converting thermal energy directly into electrical energy It is composed of pairs of thermocouples which are connected either in series or in parallel Thermopiles are used in thermoelectric radiation instruments when the output of a single pair of termocouples is not large enough See Moll thermopile, Eppley pyrheliometer
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
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
An electronic device that converts thermal energy into electrical energy
A large number of thermocouples connected in series
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
An instrument of extreme sensibility, used to determine slight differences and degrees of heat
an array of usually series connected thermocouples designed to increase to signal level and or provide a degree of spatial temperature averaging See the Thermocouple page
A group o thermocouples connected in series to increase voltage output
{i} instrument for measuring minute changes in temperature
a set of thermocouple junctions connected in series in order to boost the voltage to a meaningful amount (usually measured in millivolts) Thermowell: A threaded or flanged closed end tube which is mounted directly to the process or vessel, designed to protect the thermocouple from the process surroundings Transmittance: the fraction or percent of a particular frequency or wavelength of electromagnetic radiation that passes through a substance without being absorbed or reflected
An arrangement of thermocouples in series such that alternate junctions are at the measuring temperature and the reference temperature This arrangement amplifies the thermoelectric voltage Thermopiles are usually used as infrared detectors in radiation pyrometry
