K Thermocouple Industrial Precision Measurement Board

I'm seeking a professional with expert knowledge in precision analog design. Goal of the project is a small prototype board to measure K type thermocouple elements - with two different approaches. Additionaly obvisouly a MCU will take place - as well as RS485 communication.

Absolut main aspect is an accurate (in sense of stability, low noise and absolute value representation) K thermocouple element measurement. Two approaches are forseen - using the high precision MAX31856 as well as the AD8495 in conjunction with a 20-bit SAR and 24-bit SigDelt ADC.

Apart from the ADC proposition the project comprisis of a full circuit and PCB creation. Additionaly also the needed firmware for the respective communication (over SPI) shall be properly implemented (well structured and with readable comments). Finally also testing should take please for measure the achievable performance of the proposed and implemented solutions.

Please read carefully the attached project sheet with even more details. Looking forward to work together with an experienced engineer in the analog design and embedded domain.

Feel free posing any questions before bidding for the project.
