Temperature Measurement

The quality of heat transfer data depends, to a large extent, on the accuracy of temperature measurements. Errors in temperature measurement may be due to calibration errors and/or application errors. This paper describes some common methods of temperature measurement and estimates the precision commonly attainable with these devices. The calibration of thermometers is also discussed. The problems of surface temperature measurement, fluid temperature measurement, and bulk temperature measurement are discussed in some detail and some specific examples are included.
