ther·mo·cou·ple

(ther'mō-kŭp'ĕl),
A device for measuring slight changes in temperature, consisting of two wires of different metals, one wire being kept at a certain low temperature, the other in the tissue or other material whose temperature is to be measured; a thermoelectric current is set up that is measured by a potentiometer.
Synonym(s): thermojunction

What is a thermocouple? A thermocouple consists of two wires made of dissimilar metals, joined together at one end.
Cleanliness: The thermocouple cover should be free of oxide buildup, which can distort the temperature reading.
As for thermocouple placement, if a particular PCB has, for example, two BGAs in the board and comes in a panel of four small boards, thermocouples need to be placed in those eight locations of those four boards.
The thermocouples were located TC1: 14.25, TC2: 6.25, TC3: 4.25 and TC4: 2.75 mm from the central plane of the cut respectively.
A thermal profiler can accommodate nine or more thermocouples. Usually, about five or six are used on one side for a complex, BGA-laden PCB.
If the dimensions and material constants of sheathed thermocouples are known, it is possible to calculate the time behaviour of the sheathed thermocouples.
Omegaclad XL probes in the BLMI variation are also configurable with two independent thermocouples. This dual configuration can be used to operate both an alarm controller and a process instrument simultaneously.
The USB-4718 Thermocouple Module uses either USB 2.0 or USB 1.1 buses and supports seven types of thermocouples (J, K, T, E, R, S, B), six voltage input ranges, and 0 ~ 20mA or 4 ~ 20mA current input compatible with a variety of sensors.
Thermocouples have been used in validation studies for decades.
