Type K Thermocouple Sensor Amplifiers with Cold Junction Compensation Using AD595-AD594

The sensor project is based on AD595 IC from Analog devices.  AD595 is a complete instrumentation amplifier and thermo-couple cold junction compensator on a monolithic chip. It combines an ice point reference with a pre-calibrated amplifier to produce a high level (10 mV/°C) output directly from a thermo-couple signal. Pin-strapping options allow it to be used as a linear amplifier-compensator
