I’m looking for information on pressure-type thermometers, or an explanation of the fluids used in the bulb – what kinds of fluids are there? It would be great if I could get some pictures as well. Thank you in advance!

The medium in gas-type thermistors is mostly nitrogen ； The medium in liquid thermistors is mostly xylene, methanol, or glycerin ； The medium in steam-type thermometers is mostly chloromethane, chloroethane, and propane. The gauge structure of a pressure-type thermometer is the same as that of a spring pressure gauge; it consists of a temperature bulb filled with a medium, which is connected to the spring pressure gauge via capillaries.
Are there any pictures? It would be great to receive a few pictures as a thank you!
