PLATINUM RESISTANCE THERMOMETERS

RTD’s are sensors used to measure temperature by relating the resistance of the RTD element with the temperature. A Pt100 is a device with a typical resistance of 100 Ω at 0°C. It changes resistance value as its temperature changes following a positive slope (resistance increases when temperature is increasing. RTD’s can be made from a variety of pure materials, most notably platinum, nickel or copper and it is this material that has a predictable change in resistance when the temperature changes. Our RTD’s are accurate, repeatable and interchangeable over a wide operating range and can be supplied with a plain stem, fixed process connection and terminal heads. Here at Thermelec we offer both Watlow and our very own range.
