Is a thermojunction the same as a thermocouple?

No. A thermojunction is the specific point where two dissimilar metals join in a thermocouple. The thermocouple is the complete device containing one or more thermojunctions.

Can 'thermojunction' be used as a verb?

No, it is exclusively a noun in technical English.

In which industries is this term most common?

Process control, automotive engineering, aerospace, HVAC, and any industry involving precise temperature measurement.

What's the difference between a thermojunction and a thermistor?

A thermojunction relies on the Seebeck effect (two metals), while a thermistor is a single semiconductor material whose resistance changes with temperature.

Is “thermojunction” formal?

Thermojunction is usually technical/scientific in register.

How do you pronounce “thermojunction”?

Thermojunction: in British English it is pronounced /ˌθɜːməʊˈdʒʌŋkʃən/, and in American English it is pronounced /ˌθɜːrmoʊˈdʒʌŋkʃən/. Tap the audio buttons above to hear it.
