What is a "vapor bulb thermometer"?

The problem statement
vapor bulb thermometer

I'm simply looking for a definition. I haven't been able to find it on the internet. Before looking in a library, I was wondering if anyone knows which book to look for, or where on the internet a definition could be found.

This is not for a test. I simply don't know what a vapor bulb thermometer is.

Thank you.

Thank you for the link.

However, can you also explain how it works?

From the US Patent and Trademark office...


United States Patent 5,609,418
Black March 11, 1997

Clapeyron thermometer


Abstract
A high resolution thermometer operated by the pressure of a solid/liquid se mixture is characterized by a vessel containing the mixture, a pressure sensor and a pressure indicator. A relatively small change in the temperature to be measured causes the proportion of solid and liquid in the vessel to change, thereby producing a dramatic change in pressure which can be measured with greater accuracy than the relatively small temperature change. Temperature is determined by converting the pressure to temperature using the appropriate thermodynamic relationship.



This patent references prior art that describes the operational principles of a vapor bulb thermometer.
