The dial gauge on the 5th floor is not of the PT100 type; it’s a BA2 type. This type is no longer used nowadays, as all PT100 gauges in use today have a value of 138.5!

Oh, when was BAT2 established as a standard?

BA2 is the calibration code for platinum resistors from over 20 years ago. The client wants a comparison table of thermoresistors and thermocouples; it’s easy to find one by just searching online

The two-way lookup table for thermal resistors and thermocouples at http://tools.sadi.cn/fenduhao.html includes 11 types of thermal resistors and 8 types of thermocouples from the 1960s to the present, with extremely high precision

There is an approximate conversion formula: 100 ohms correspond to 0°C, and for every increase of 0.39 ohms in resistance, the temperature rises by 1°C. It can be roughly converted in this way
