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.

Suppliers of Pt100

Links to selected manufacturers and suppliers of Temperature Sensors.

Market overview

Some designs of Pt100 resistance thermometers are standardized in DIN and thus allow easy interchangeability, even of products from different manufacturers. In addition, there are a large number of very different variants of Pt100 resistance thermometers that have proven themselves for specific applications or are built to customer specifications.
Almost all manufacturers can supply all variants, i.e. ultimately it is mainly quality, service, delivery time and price that decide which supplier to choose.
An exception are Pt100 resistance thermometers, which are used in hazardous areas.
For this purpose, the manufacturing company required an approval.
If special certificates (e.g. SIL) are required, there is a further restriction of the suppliers available for selection.
Below is a brief overview of the most common designs on the market for special applications.
