What is the difference between special limits of error, standard limits of error, and extension grade thermocouple wire?
Special limits of error thermocouples are made with a higher grade of wire, which increases their accuracy. They are more expensive than the more common standard limits of error thermocouples which use standard “thermocouple grade” wire. An excerpt: “We are ...
How are vacuum furnaces used in the process of minting coins?
Advanced gas quenching techniques in the vacuum heat-treating process for superior coining die performance involve optimizing the micro-structure of the die surface to provide uniform hardness and minimizing distortion. An excerpt: “The minting industry has to be compliant to the ...
How do you match a primary and secondary pump?
This blog describes the factors involved in matching primary pumps to support the continuous operation of secondary pumps and to ensure safe and optimized performance. The consequences arising from a wrong combination or “matching” of primary and secondary pumps can ...
What are some vacuum furnace pumping system failures and their solutions?
For the many vacuum furnaces in use around the world, the vacuum pumping system is a critical component. To get the best value from the vacuum furnace system and to extend its useful life, regular and careful maintenance of the ...
