Hello Freaks, (I mean that in a nice way of course)

My google foo has failed me. :(

I have written software to process NTC thermistors using the Beta version of the Steinhart"“Hart equation.

I wish to add some processing to handle some different types of thermistors including some which are classified as 10k type 2 or type 3. Obviously these are 10k@25Â°C types but I have been unable to find either the Beta value or even A,B,C coefficients corresponding to type 2 or type 3.

Am I correct in assuming type 2|3 refer to a standard R-T curve or am I mistaken?

All I seem to find is a table for R-T. Working backwards, I have used these to calculate the Beta value however it varies considerable across the range and does not instill me with a lot of confidence.

Does anyone know the details are or where I might find them?

Steve
