Despite having dedicated RTD cards on other platforms, this doesn't exist on PXI. The existing bridge input cards have significantly higher sample rates than needed for typical temperature measurements, and it would be nice to have a more economical drop-in option for RTDs that supported more channels.
rgvdh@rdf: The NI PXIe-4357 supports 2/3/4-wire connections with Pt100 RTDs. Could you share more information about the need for different R0 values? Are you replacing an existing system that has a mixture of RTD types, or does your application require different RTD types?
I work for a company that makes RTD sensors. In our industrial probes 100 ohm is our most popular product, but we also see a lot of 1000 ohm (more commonly used with 2-wire systems) and occasionally 200 and 500. (typical ordering chart example)
We also see quite a few customers using reference grade platinum instead of DIN.
