Pt100 - Sensors

Temperature measurement with Pt100 resistance thermometers-

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:
