The operation and characteristics of an absolute optical encoder used in automation applications are presented.

Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.

Learners examine dew point and the two types of humidity values, absolute and relative, along with the types of instruments used to measure them. The activity includes a video clip and a quiz.

Learners compare the three scales used in pressure measurements: gage, absolute, and vacuum. A brief quiz completes the activity.

The learner will gain an understanding of robot motion control by comprehending the fundamentals of the encoder.

Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.

In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.

In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.

Learners study the most common ways to measure fluid flow for industrial processes including absolute quantity, percentage, volumetric flow rate, and mass flow. A brief quiz completes the activity.
