ACCP SUBCOURSE NUMBER MM 0483, THERMOMETRY
(4 Credit Hours)
INTRODUCTION
Everyone is concerned with the effects of temperature. It affects your comfort and
discomfort; the temperature of your body is directly related to your health. In the
technical field we are also concerned with temperature. High temperature may cause
equipment to overheat or burn out, while low temperature may prevent equipment from
reaching optimum operating temperature, thereby reducing efficiency. As our technology
advances, temperature becomes even more important. The success or failure of an
astronaut's voyage into space, or even his life, can be jeopardized by extreme
temperature.
Since temperature affects all factors of our daily lives, it is essential that we be able to
accurately determine temperatures. We use various types of thermometers to do this and
these thermometers must be accurate. We know that under controlled conditions, certain
events occur in nature at definite points on the heat scale. By agreement among the
member Nation of the International Conference of Weights and Measurements, these
points have been assigned definite temperatures. Based on the occurrences of these
natural events and international agreements, we can calibrate and/or compare
thermometers to determine their accuracy. As calibration specialists, you will be required
to determine the accuracy of various thermometers.
The importance of temperature measurement cannot be overemphasized. Your value to
your unit will be enhanced significantly through the increased versatility you develop
from this subcourse.
This subcourse is organized as follows:
Lesson 1 Introduction to Thermometry.............................. 1 Hour
Lesson 2 Calibration and Use of Standards........................ 2 Hours
Examination...................................................................
