In this animated object, learners examine the hysteresis function of a sensor.
Dynamic Braking Circuits
By Terry Bartelt
In this animated activity, learners examine the operation of a dynamic braking circuit used to quickly stop a motor.
The TI-86 Scientific Calculator: Complex Number Conversion
By Patrick Hoppe
This primer introduces the student to the proper method of complex number conversion on a TI-86 calculator.
Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.
Sine Wave Fundamentals: Practice Problem #3
In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.
By Terry Bartelt, Terry Fleischman
The learner will understand how to correctly wire a three-wire sinking and sourcing sensor.
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.
The Hydraulic Pressure Switch
This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.
