Dear Sir:
I was overlooking the NI TC01 spec sheet and I would like to know the exact temperature range that I can safely install a NI TC01 with a thermocouple connected to it.
If you look at the TC01 spec sheet under the title "Temperature measurement ranges",
the spec sheet says:
"Works over temperature ranges defined by NIST (J, K, R, S, T, N, E, and B thermocouple types; the E type has a maximum limit of 900 °C.)"
However, I scroll down the spec sheet and I see graphs that show the performance of these thermocouples and I see the measurement errors that rise exponentially at low temperatures.
I do not want to install the TC01 and thermocouple at any point in the low temperature range where the error curve begins to rise exponentially.
When I install these these thermocouple devices I would like give interested "parties"
(customers, project managers, etc.) a well defined "reliable" minimum and maximum
temperature range and avoid the point where the error curve begins to exponentially rise.
In the NI TC01 spec sheet, only the E type thermocouple is specified to a maximum temp. of 900 degrees C.
Can an NI engineer show me a reliable method, using the TC01 spec sheet,
draw a straight line through the "flat" section of the graph and specify (enumerate) a reliable Tmax and Tmin temperature range using the K type thermocouple graph as an example?
Other manufacturerers of temperature measuring equipment explicitly define the
reliable temperature ranges of their products, however, I prefer to use the NI line of products because of the Labview integration feature.
I have attached the NI TC01 data sheet for your convenience.
