Many if not most RTDs are 100Ω at 0°C; this one is 1000Ω, presumably for finer resolution. I think other mfrs make equivalent ones, and you can compare the spec sheets. Note that this one is more than just an RTD; it is a transmitter that converts ohms into a 4-20ma DC signal.

For what application u r taking this one .
