Thermocouple Introduction and theory

what each thermocouple is, we can mix thermocouple types on the same isothermal junction block (often called a . zone box) and make the appropriate modifications in software. The junction block temperature sensor R. T. is located at the center of the block to minimize errors due to thermal gradients. Software compensation is the most versatile
