Learners follow the steps required to perform the Ziegler-Nichols reaction curve process identification procedure.
Ultrasonic Flowmeters (Screencast)
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.
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.
Derivative Control Mode Analogy (Screencast)
In this animated object, learners view a race of two boats as an example of how the derivative function of a PID controller shortens the time duration of an operation.
Temperature Emissivity of Non-Blackbodies (Screencast)
Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
