linearization algorithms help needed

[CM600]

Hi all,
I need algorithms for thermocouple linearization, aproximation.
10x in advance

Hello,
See for example
www.sensorsmag.com/articles/1297/sw1297/main.shtml
But a google search may give you a lot of more info.

Best regards

I think if range of temperature is large(eg. -200~1300C), it is not fit use linearization.

hi

Is there any article like as sensor magazine article for linearization the RTD sensors?

I need the polynomial of RTD for linearizing it like as THC polynomial.

Bye

If your sensor is measuring a wide temperature range, it might be better to use a lookup table. You will get superior accuracy and there is no long polynomial to crunch through. You don't need a huge table; simply interpolate between table entries.
