Since i saw this now twice in videos:
Heating the Pt- or whatever sensor anywhere but the tip is useless. The actual sensor (eg. 100 ohm Pt) is in the very tip. The rest is just casing. And of cours there are sensors without the case, so very low thermal mass but still with the accuracy of Pt 100/1000.

If you are into 3D Printing. you should make a video about the PT100 RTD in higher precision applications. I use a PT100 with a daughter board on my Duet WiFi to get up to about 400 C. Look into the Duet WiFi and dc42 fork or RepRapFirmware. I was confused about how to wire it up initially.

Is it me or is this just a matter of measuring the resistance of the RTD easily using a multimeter? O I was wondering, the RTD says it's capable of 850 degrees celsius. But can you put the RTD on the surface of for a example a aluminium plate without it burning?

Finally there is something where I am better then this guy. I made the sensor using ATMEGA 16 and complementary components and it matches with the temperature shown by GOOGLE. Feeling proud

This guy is the storyteller of electronics, he says thats a subject for another video almost as much as the storyteller says thats a story for anothers day.
