They're all real- it's just that there is no international standard  for Cu RTDs that I know of. You have not mentioned why you want this-  obviously if you are buying the sensor you are going to want to go to  the manufacturer for the data. If you are trying to make a general  purpose indicator or controller.. you might want to use this (assuming  the reference temperature of 25 C is appropriate..)


Again, scale the numbers appropriately (5:1 in this case). Anything that's
within a degree or two C at the extremes is probably better than the sensor

Where exactly did you run into a 50 ohm copper RTD?
