platinum resistance thermometer
Quick Summary
A platinum resistance thermometer is a type of thermometer that uses a wire, typically platinum, as its sensing element. This instrument measures temperature by detecting changes in the electrical resistance of the wire. As the temperature changes, the electrical resistance of the platinum wire also changes, allowing the instrument to indicate the corresponding temperature. Platinum is a suitable material for resistance thermometers because its electrical resistance varies predictably with temperature over a wide range. These thermometers are important tools for temperature measurement in various fields, including scientific research and manufacturing.123
