NI9219 temperature measurement range

[NCLbingji]

I want to measure temperature from -100degreeC to 160degreeC with NI9219.

Is it possible to measure this range with any K-type thermocouples? Any advice is welcome. Thank you.

Should work.The spec tells +/- 125mV for TC measurements. So even if your (external 😉 )CJC is at 1500K and your tip is at 170K you can do the measurements 😉 (about 60mV)

Depending  on how your TC is build (housing, strain due to thermo mechanics, melting/conductance of isolators ) no problem with the range . My tables go from about 3K up to 1500K.

A good source for TC knowledge:
Manual on the use of thermocouples in temperature measurement,
ASTM PCN: 28-012093-40,
ISBN 0-8031-1466-4

(Page1): 'Regardless of how many facts are presented herein and regardless of the percentage retained,

                all will be for naught unless one simple important fact is kept firmly in mind.

                The thermocouple reports only what it "feels." This may or may not the temperature of interest'
