In this animated object, learners examine the signals produced by sourcing and sinking two-wire sensors. A brief quiz completes the activity.

Students read how to calculate the size of a hydraulic cylinder that is required for a particular application. Mathematical formulas are provided.

Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.

Learners practice revising poorly written directions by applying criteria for giving directions.

In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.
