10 Types of Thermometers: How to Use Them? | Linquip

2021-07-22· Thermocouple Thermometer. Bimetallic strip thermometers are made from two different metals. When the temperature rises, the metals become entangled and expand at different rates. The two metals in these thermometers also expand to different lengths. As a result, the bimetallic strip bends or coils towards the side with a lower thermal expansion coefficient. When the bimetallic strip vibrates ...

How do thermocouples work? - Explain that Stuff

2021-06-16· If you want to measure the temperature of something as hot as a volcano, an ordinary thermometer isn't any use. Stick the bulb of a mercury thermometer into volcanic lava (which can be well over 1000°C or 1800°F) and you'll get a surprise: the mercury inside will instantly boil (it turns from liquid to gas at a mere 356°C or 674°F) and the glass itself might even melt (if the lava is ...
