Learners study how a hydrocarbon gas sensor operates and why it is used. A short quiz completes the activity.
Excess Gain of Optical Sensors
By Terry Bartelt
In this animated activity, learners examine how to change the gain of an optical sensor to overcome environmental conditions and distance.
The Bridge Rectifier
Learners see how a bridge rectifier converts an AC voltage into a pulsating DC voltage. A brief quiz completes the activity.
Series-Parallel Circuit Analysis Practice Problems: Circuit #5
By Patrick Hoppe
Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.
Hall-Effect Sensor Application
Learners view practical examples of how a Hall-effect sensor is used.
Displacement Level Sensors
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.
By John Casey, Terry Bartelt
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.
Incremental Encoder Quadrature Modes
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.
In this animated activity, learners examine the operation of an ultrasonic sensor and the procedure to perform zero and span adjustments. A brief quiz completes the object.
