Dear All:
We use LTC2984 demo board P/NDC2420A-KIT to test K-type & PT100 performance ,but found K-Type sensor data error it's need re-calibrate in LTC2984 system?? have any suggestion provide to me? thanks
CH3: K-type .CH9:PT100

Hi JackH,
I moved your question to the Temperature Sensors section.
The accuracy of the K-type thermocouple depends on it's cold junction compensation sensor. What are you using for the CJ sensor?
Another thing to keep in mind when comparing sensors of different types is the thermal time constants for each sensor. If the thermocouple is a bare-wire type, it will respond much faster than a PT100. How are you controlling the sensor temperature?
