Hello mehmet64
Is this a new project?
If so, I would take the MAX31855 replacement module.
The MAX31855 performs cold-junction compensation
and digitizes the signal from a K-, J-, N-, T-, S-, R-, or
E-type thermocouple. The data is output in a signed
14-bit, SPI-compatible, read-only format. This converter
resolves temperatures to 0.25NC, allows readings as high
as +1800NC and as low as -270 NC, and exhibits thermo -
couple accuracy of ±2 NC for temperatures ranging from
-200NC to +700 NC for K-type thermocouples.
