AMS2750F Thermocouple Requirements
Our goal is to keep our clients up to date on the new changes to AMS2750. In today’s blog post, I’m discussing how AMS2750F now permits Type M and Type C thermocouples. It is important to understand the use and limitations of thermocouples prior to use.
The chemical composition of Type M thermocouples is Type M 82%Ni, 18%Mo, 99.2%Ni, 0.8%Co, by weight. When compared with the chemical composition of Type K thermocouples (90% nickel, 10% chromium - 95% nickel, 5% aluminum and silicon), it is clear that they are able to share the same extensions wire.
Type C thermocouple composition is 95%W, 5%Re–74%W, 26%Re, by weight and is designed for high temperatures (2328 degrees Celsius).
To learn more about the design, composition and use of thermocouples, attend an upcoming AMS2750 training course, Principles of Pyrometry.
If you are interested in better understanding all the changes within AMS2750F, obtain conformance tools and learn how to implement successfully, join us July 30, 2020 for a 2-hour virtual training.
