What is the significance of a temperature gradient when there are “intermediate materials” in the thermocouple circuit? For the purpose of this blog, “intermediate materials” is defined as a portion of a thermocouple circuit that has a
What does the “Certificate of Thermoelectric Calibration” represent? A “Certificate of Thermoelectric Calibration” is provided by Concept Alloys for all pairs of matched thermocouple materials that are intended to meet an accepted nominal emf vs.
What does the "initial calibration tolerance" mean? Materials for “letter designated thermocouples” (as designated by ASTM) and certain other common thermocouple types are produced to meet nominal emf vs. temperature curves that are accepted by
