Resistance Temperature Detector search for term

A temperature measuring device made of wire wound around a core and isolated in a seath. It works on the basis that resistance changes with temperature. That is, the hotter they become, the larger or higher the value of their electrical resistance. They are very precise, respond quickly and are nearly linear over a wide range of temperatures. They are most commonly made from platinum.
