Among them, the common types are bimetallic and gas expansion thermometers. However, some people are often confused about the advantages and disadvantages between these thermometers. So let’s look at the differences between these thermometers. 1. Bimetal Thermometer Bimetal thermometers are made of two different kinds of metal bonded together. Each metal expands at different rates when heated, and by measuring this difference, we can measure temperature. Generally, the metal sheets are made into a coil, with the “free end” connected to the pointer shaft and the “fixed end” where the thermometer will be attached. When the temperature rises, the metal at the free […]
