I have a question concerning the accuracy specification of the NI-9217. Curious if NI or someone else has more detailed information about the accuracy specifications. The specification for the NI-9217 states for a 3 wire configuration (which is quite good):
Measured Value Ambient 25C Ambient -40C to 70C 20C to 30C
-200C to 150C 0.20C 0.5C ???
Interested if NI possibly has a graph/data that might suggest what the accuracy might be in a laboratory temperature environment. Would be an additional column to the datasheet 🙂
Not really a problem. Just curious if NI can provide more accuracy information. The NI-9217 datasheet specifies:
For measured value -200C to 150C Typical 25C: Accuracy 0.2C Maximum -40C to 70C: Accuracy 05C
In our applications, the NI-9217 will be used in a Lab enviorenment that will be typically 20C to 30C and are measuring ranges between 0C and 100C. Is there possibly a graph that can be disclosed that shows accuracy over different ambient temperatures?
I do not think that we have a graph with the data for different ambient temperature, but from what your description implies (ambient temperature of 20-30C measuring 0-100C) the accuracy should be pretty close to 0.2C. The slight fluctuations in the ambient temperature should not effect the accuracy enormously 🙂 .
