Pt100 - resistance thermometers

-List of available standards-

About the site

This is a private information page about electrical temperature measurement with resistance thermometers (e.g. Pt100, Pt500, Pt1000). My experiences of many years in the field of measurement and control technology are recorded. I do not take over any liability for incorrect information and would be pleased about further suggestions and requests for additions.

What are standards and guidelines?

The measurement of temperature, in particular with electrical temperature sensors (e.g. Pt100), is described in many technical rules.
This defines manufacturer- and country-independent standards that guarantee a certain quality, safety and interchangeability of the temperature measuring devices.
There are national standards (DIN, VDI/VDE), European standards (CEN, CENELEC, ETSI), and international standards (ISO, IEC).

The best-known standards are:
  • DIN-Standard
    DIN standards are widely used in Germany. These are prepared by the German Institute for Standardization (DIN) and distributed by the Beuth-Verlag. Compliance with DIN standards is not binding. However, it is often required or at least recommended by law in many industries and sectors (e.g. the construction industry, electrical engineering, the automotive industry or medical technology)
    The designation of a DIN standard, consists of the 3 letters "DIN", a number and a date of publication:
    Example: DIN 43147:1989-06
  • DIN EN Standard
    The DIN EN standards ("German Industrial Standard European Standard) are European standards that are valid in all EU countries. They are an important part of European harmonization.
    These standards are developed in cooperation with the European Committee for Standardization (CEN) and the International Standards Organization (ISO). Existing DIN standards are often taken as a basis and supplemented for the European market.
    The designation of a DIN EN standard, consists of the 5 letters "DIN EN", a number and a date of publication:
    Example: DIN EN 43147:1989-06
  • ISO- Standard
    ISO Normen werden von der International Organization for Standardization (ISO) entwickelt und veröffentlicht. These standards are used in many countries around the world.
    The designation of an ISO standard, consists of the 3 letters "ISO", a number and a year of publication:
    Example: ISO 9001:2015
  • VDI/VDE Guidelines
    The VDI/VDE guidelines are developed and published. by the Association of German Engineers/Association of German Electrical Engineers. Compliance with VDI/VDE guidelines is recommended or mandatory in many industries and or prescribed. VDI/VDE guidelines are also internationally recognized and are often used as reference standards in other countries. VDI/VDE Richtlinien sind auch international anerkannt und werden oft als Referenznormen in anderen Ländern verwendet. The guidelines are practice-oriented and mainly refer to technical areas, such as measurement and control technology, electrical engineering, environmental technology or information technology.
