The way an industrial thermometer works depends upon the type of temperature sensor it uses. Sensor options include bimetal, liquid or gas-filled, electronic, or infrared (IR). Liquid or gas-filled thermometers use a gas or liquid as the temperature-sensing element. The liquid expands as the temperature rises in the tube and indicates the temperature. The basic design for this type of thermometer is a small-bore glass tube with a thin-walled glass bulb at the lower end.
Resizing involving cutting probably in the $50-100 range for silver or for reducing a gold ring, enlarging a gold ring with added metal could run $100-250 depending on how large the ring is - a real hefty men's ring will obviously take more metal, so more cost, than a thin wedding band.
