I need to read out the temperature of ZrO2 devices which rotate along their axis between 10-100 kHz by using dry compressed air.
The external diameters of each device are: 1mm, 3mm or 4mm, and they rotate inside a special stator
The actual rotation speed is read by an optical fiber close to the bottom where a black mark is placed.
Up to now the temperature was read out by using a PT100 thermocouple (Cu-Costantan) placed somewhere close to the top of the device (exhaust air).
I want to realize a better measuring circuit: it should read directly above to the surface of the spinning device (which is white colored), should be well miniaturized and precise.
What is the state-of-art today? A laser ray? An InfraRed sensor? Or what else?
Thanks for any advice.
