thermocouple | Definition & Facts | Britannica

Thermocouple, also called thermal junction, thermoelectric thermometer, or thermel, a temperature -measuring device consisting of two wires of different metals joined at each end. One junction is placed where the temperature is to be measured, and the other is kept at a constant lower temperature.

What is a Thermocouple Thermometer? Construction & How it ...

· Thermocouple is a temperature sensor composed of two metals that generate emfs (electromotive forces) or voltages when there are temperature differences between them. The amount of voltage produced is dependant on these differences. Thermocouples operate by exploiting the Seebeck effect. Thermocouples are popular temperature sensors found in places as diverse as hospitals, thermometers ...

Thermocouples - Engineering LibreTexts

· A thermocouple is a device, joined together from two dissimilar metal and/or semiconductor wires, used for measuring temperatures. A thermocouple is not an absolute temperature measuring device. Instead, it is a device that responds to temperature difference between test environment and reference point, that produces a potential difference as the output. Incidentally, the potential difference is proportional to temperature difference …

Thermocouples - Question and Answer The Complete Guide:

A: Yes, a thermocouple is a thermometer. Let’s define what a thermometer is: The word “thermo” means “temperature” and the word “meter” means “measure”. So a thermometer is something that literally “measures temperature”. We can look at other types of thermometers to see how they qualify as temperature meters. A mercury thermometer works by measuring the level of mercury ...

12. Temperature and physical properties -

A thermometer has a liquid in a very narrow tube, which when heated will expand and move up the tube. If you cool the liquid down, then the liquid will contract and move back down the tube. So the physical property used in a thermometer is thermal expansion. A thermistor is an electronic component called a semiconductor. When it is heated, a 'negative temperature coefficient' (NTC) thermistor ...
