Meeting Overview:
Theory and Application of Thermocouples
K.C. Sloneker
Thermocouples are widely viewed as a simple measurement tool that can be easily and widely applied to obtain reasonable temperature measurements. That is sometimes true, but sometimes it is anything but simple. The real challenge is to know when the measurement is correct and reliable and when it is not. A fundamental understanding of the basic principles of operation is required to make this determination. This tutorial starts with, where EMF is generated and includes a brief overview of the relation to thermodynamics. A complete discussion of inhomogeneity will lead to its affect on practical measurements. In closing, the results of a recent thermocouple Inter Laboratory Comparison will be presented where the results show the importance of understanding how thermocouples work.
Our presenter is Kenneth Sloneker. Ken serves as Laboratory Director for Electronic Development Laboratories and ASL US. EDL manufactures a wide range of industrial temperature measurement and metrology products. ASL US provides design, sales, and technical support for ASL in the United Kingdom. Mr. Sloneker holds a BSME with a specialty in thermal sciences. He is a member of the ASTM E20 committee on temperature and serves as chairman of the thermocouple sub-committee E20.04, Thermocouple Testing and Specifications. His current research is focused on high accuracy differential temperature measurements using thermocouples, thermocouple inhomogeneity testing, and life cycle studies of base metal thermocouples.
The training will be free of charge to NCSLI members and will begin with registration and a continental breakfast at 8:00 am. Training will take place at MACNY headquarters in Syracuse, NY.
