This animated lesson shows the operation and characteristics of thru-beam optical sensors.
By Terry Bartelt
Learners examine how air-to-open valves and air-to-close valves are used in different situations. A brief quiz completes the activity.
Parallel RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
PID Control (Screencast)
Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.
Series-Parallel Circuit Analysis Practice Problems: Circuit 3
By Patrick Hoppe
In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.
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.
