I need to calibrate an iron-nickel RTD. Our Altec 211 simulator and Fluke 754 both can’t simulate Fe-Ni. What do you guys recommend?

EDIT (at the top): So, after much investigation I’ve come to find out that yes it was an iron-nickel 1000ohm RTD.

I spent quite a while hunting for any RTD calibrator I could find that said it would calibrate iron-nickel elements and found not a single one. Eventually I learned that the Beamex mc-6 (which we have) can have custom RTD profiles. I just plugged in the coefficients from minco’s 1000 ohm iron-nickel RTD table and saved it, then hooked up with loop power supplied and it worked.

So anyway, people had been signing that one off as complete… it’s for exit air temp from auxiliary air handlers.

——————————————————————————

Any test equipment that can actually simulate nickel-iron RTDs will do. It doesn’t have to be documenting or anything, I can do that part with the fluke.

I used a decade resistance box to verify I’m not going crazy and that the transmitter I’ve got actually outputs ANYTHING (after trying to get the output to budge with all our other test equipment). I supplied power with “loop power” from the fluke and asked it to also read mA return. It was 4mA up until around 790 ohm, then linear response until around 1130 ohm. it’s a Minco model TT508FB(-20/120)F1Y.

And if any Minco employees are reading this… your website is broken.
