Platinum resistance thermometers

Platinum resistance thermometers are precision temperature sensors that measure temperature based on the electrical resistance of platinum, a metal that changes its resistance with temperature. When the temperature increases, the resistance of the platinum wire also increases in a predictable way. This allows for accurate temperature readings, making them ideal for scientific and industrial applications. They operate over a wide temperature range and are known for their stability and reliability, which is why they are often used in demanding environments, such as laboratories and manufacturing processes.
