Thermometry Issues in Destruction Kinetics Measurements

Published

Author(s)

Dean C. Ripple

Abstract

Of all the aspects of destruction kinetics measurement, the one taken most for granted is temperature measurement. The ubiquity of digital thermometers and their ease of use have disguised potential accuracy issues in the range of temperature encountered in destruction kinetics. This presentation will focus on temperature measurement itself. Particular topics include: ensuring thermal equilibrium between the sensor and the product, typical repeatability and drift of various types of thermometers, methods to ensure traceability of measurements to national standards, and validation of readouts and sensors. I will also discuss special issues for temperature sensors exposed to high pressure or to electromagnetic interference.
