Resistance thermometer sensors (RTSs) and thermocouples are the temperature sensors most widely used in industrial
temperature measurement. They have the advantages of simple construction and ease of use, making for convenience in
However, if correct application methods based on the proper standards are not followed, highly accurate measurements
cannot be expected.
This document is a compendium of the basic data relating to resistance thermometer sensors and thermocouples. *This
second edition reflects IEC and JIS revisions (thermocouples) of July 1995. We hope that this document will aid you in
comparing the various underlying standards from an international viewpoint, and in deciding which standards to follow.
This document also provides information on vital parameters such as operating temperature ranges and tolerances.
