Abstract

The invention relates to a thermocouple for sensing the temperature at a measurement point, comprising a first conductor that has a first end and a first terminal, and a second conductor that has a second end and a second terminal. The first end of the first conductor and the second end of the second conductor are in electric contact with one another at the measurement point, while the first terminal of the first conductor and the second terminal of the second conductor can each be connected to a terminal line. The first conductor and the second conductor are applied to a substrate using thick-film technology, the first end of the first conductor and the second end of the second conductor overlapping in at least some sections at the measurement point. A hot runner nozzle has a heater and a thermocouple according to the invention.
