PT100s + Intro
Hi - I'm a research engineer working in the field of precision measurement for SMS Ltd. Currently looking to measure temperature to extreme accuracy, cheaply! Ultimately a PT100 will be included in a new product, but until then we will probably use a Pico 104 temperature logger for R&D.
My technical question concerns the classification of PT100 sensors. What physically differentiates (say) a Class A from a Class B? Is it merely calibration, or are there internal material/physical differences?

Hi Dirk,
There is no physical difference.
The difference is the tolerance of resistor used.
Therefore the typically accuracy of the probes are:
Class A = ±0.15 °C @ 0 °C
Class B = ±0.30 °C @ 0 °C
Kind Regards,
