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
a group of thermocouples connected in series
a more sensitive and precise instrument, consisting of many thermocouples in series
a number of dissimilar junction thermocouples connected in series to increase the voltage for very small heat rise
a number of thermocouple junctions connected in series
a probe that contains multiple thermocouples, therefore it can produce a larger electrical current
a set of thermocouples connected in series
A group o thermocouples connected in series to increase voltage output.
Multiple thermocouples connected in series so that alternate junctions are at the reference and measuring points. The result of this type of arrangement is an increased output for a given temperature differential.
Apparatus that consists of a number of thermocouples combined so as to multiply the effect and is used for generating electrical current.
A number of thermocouples connected in series to produce more DC millivolts than a single thermocouple. Depending on size, the DC millivolts range between 250 and 750 millivolts.
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.
A number of thermocouples connected in series to produce a higher voltage than a single thermocouple.
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 pile of thermocouples, which when heated, produce a small DC current (also called a thermogenerator). A thermopile produces more current than a thermocouple.
A number of thermocouples whose junctions are assembled in series to magnify the Seebeck voltage and increase the sensitivity of the reading. Thermopiles have been used in remote sensing pyrometers.
A large number of thermocouples connected in series.
A "thermometer" for measuring heat radiation consisting of several thermocouple junctions.
A series of individual thermocouples connected in series, used to generate a sufficiently high voltage to operate a gas valve without the aid of outside power. (Also called "self-generating.")
A thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of thermocouples either connected in series or in parallel. Thermopiles are used in situations where a single thermocouple generates insufficient output.
