    rtd conversion table

    The ASTM standard E1137 deals with RTD's. You can buy the standard from ASTM

    Omega offers their "The Temperature Handbook", which contains conversion charts. It is free, but shipping is not cheap.

    Try using this .pdf. I don't know how accurate these coefficients are. I can check them on Monday, when I get back to work. Note that for temperatures above 0C, the formulas are simpler.

    [{(0.00389)(PT100)}deg. C]+PT100 = Rt, you can work it out in this formula by substituting the RTD type like PT200, PT500

    In the equation {(0.00389)(PT100)}deg. C]+PT100 = Rt

    what is the value of PT100?
