RTDs, or PT100s, are 100 ohm temperature sensors that use changes in resistance of the material in which it is constructed to measure the temperature of a particular process. RTDs typically provide more rapid and precise temperature measurement when compared to thermocouples.

They are available in low temperature range types (both wire-wound and thin-film), or in high temperature range types (wire-wound) as single or duplex platinum elements. RTDs are used on dehydration units, condensate separators, chemical reactors and other applications. They can be formed or bent, depending on size, and fitted with a variety of termination options.
