Noun1.thermocouple junction - a kind of thermometer consisting of two wires of different metals that are joined at both ends; one junction is at the temperature to be measured and the other is held at a fixed lower temperature; the current generated in the circuit is proportional to the temperature difference
thermometer - measuring instrument for measuring temperature

This guarantees a quick response while avoiding effects of radiation on the heat absorbed by thermocouple junction.
To simulate a rework site with an attached component, four layers of 3-mil Kapton tape were used to cover a high response rate thermocouple junction at a bare [micro]SMD site.
Remember that a thermocouple measures the temperature only at the location of the thermocouple junction.
A thermocouple gauge contains an electrically heated filament and a thermocouple junction in physical contact with it.
The reduction in RH can be measured via the temperature depression from evaporation of a wet thermocouple junction (psychrometric mode of measurement).
The four new precision thermocouple amplifiers each convert the small voltages generated by a thermocouple junction into a 5 mV/xC analog signal that can easily be read by an ADC (analog-to-digital converter) or microcontroller.
Johnston and Kazmer [1], however, have shown that direct losses from the thermocouple junction through the steel sheath toward the barrel or the mould may occur.
The thermocouple junction then could be located with precision using image analysis software.
For example, when a melt thermocouple probe is positioned in the barrel of an extruder, the machine barrel temperature dominates its response because heat transfer from the barrel to the thermocouple junction is much more efficient than is heat transfer from resin to thermocouple.
