DEFINITION

Classification: 374/100

TEMPERATURE MEASUREMENT (E.G., THERMOMETER):

(under the class definition) Subject matter for making a quantitative determination of a temperature, or of a temperature-related parameter which is not otherwise classifiable.

(1) Note. The term "quantitative" requires a numerical result of more than two values.

(2) Note. The term "temperature-related parameter" is a quantity having a value that is a function of plural temperatures, or of temperature and another variable and not elsewhere classified, see subclasses 101+ below.

(3) Note. A device providing the temperature determination is often designated as a "thermometer" or pyrometer", both terms being used in this class.

(4) Note. In this and indented subclasses the term "sensing" will denote the immediate effect of a parameter and the term "indicating" will denote the creation of a humanly perceptible action.
