This is very interesting, can't wait to see how your home made one works, I may do the same...

This is our sensor and has a 0-300 deg C range can be screwed to a top fin under the shrouds or
just on one of the tin screws as shown.
Like to know more about this!
Who, what , where, how much...

That is a 0-300deg C sensor.
Most engine temp sensors only go to 150C so no good for detecting and dealing with overheat conditions in the VW aircooled.
Since they are expensive and several end users decided to use them as grounding wires
we now use either the PLX cht thermocouple setup or for the cheap ass route just a M10 regular air temp sensor screwed to the tin pointing at the fins-works just fine

Thermocouple is used by zero OEMs, so follow their r&d lead.
OEM's are usually cheap baztards and have no real need to measure and monitor temp above 150c
so will stay away from the extra complexity and cost of thermocouple circuitry.
Of course thermocouples are widely used throughout industry/aerospace where greater temperature range and accuracy
are needed.
I'd like to see someone measure EGT with a thermistor
So you do closed loop EGT? Hmmm. People need to get their cars running, not worry about aerospace. Ever seen a shuttle launch delayed because of a bad TC reading?
It might be complicated for you to understand but the guy asked a question and I answered it.
No one asked you to butt in with your OEM R+D and space shuttle BS
OK Pumpkin
I will use the most accurate sensors I can afford regardless if the OEM's use them or not. This is my motor not theirs. The motors they test in the R&D Dyno room are TC'ed up the yang. My motor is a one off so I consider it R&D, it needs to be monitored the best I can afford.
