thermojunction

9.2
A point where two different metals meet and produce a small electric voltage when heated, used to measure temperature
  • noun
  • /ˌθɜrmoʊˈdʒʌŋkʃən/

translation icon : termo-junción
  • In a thermocouple, the thermojunction connects two dissimilar metals to create a voltage output.

Examples

  • The sensor relies on a thermojunction to produce a measurable voltage when heated.

  • Variations in temperature at the thermojunction result in changes in output voltage.

  • A thermojunction forms the core of every thermocouple device.

  • The thermojunction is essential for accurate temperature measurement.

  • Many thermojunctions are used in industrial applications.

  • A thermojunction generates a voltage that helps measure temperature in thermocouples.

  • The thermojunction is crucial for converting temperature differences into electrical signals.

A place where two different metal wires join and make a small electric signal to measure temperature

is a single metal-to-metal connection that generates voltage used in temperature sensing

Surface Forms

thermojunction singular
thermojunctions plural

Morphology

thermojunction = junction (semi-transparent) = thermo + junction

The structure is clear as 'thermo-' + 'junction', but the term is specialized and its exact technical sense is not fully predictable from the parts alone.

Etymology

Thermojunction combines thermo- ('heat') and junction ('a joining point'), the same thermo- you find in thermometer. So a thermojunction is the place where two different metals meet and make a small electric voltage when warmed, which is why it is used to measure temperature.
