ای سی اندازه گیری دمای ترموکوپل و ارسال ان به صورت دیجیتال با پروتکل SPI به صورت 14 بیت و محدوده دمای منفی 200 تا مثبت 1800 درجه سانتی گراد Cold-Junction Compensated Thermocouple-to-Digital Converter
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 -270NC, and exhibits thermocouple
accuracy of ±2NC for temperatures ranging from
-200NC to +700NC for K-type thermocouples. For full
range accuracies and other thermocouple types, see the
Thermal Characteristics specifications
