Learners examine the differences and similarities between hydraulic and pneumatic systems.
Fundamentals of a DC Motor
By Terry Bartelt
Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
PLC Sourcing Input Modules
In this interactive and animated object, learners study how to wire field devices to a PLC sourcing input module. A brief quiz completes the activity.
Conductive Probe Sensors
In this animated object, learners study how conductive probe sensors are used to measure conductive liquid in a container.
Learners observe how to cascade PLC counters to extend the maximum count of one counter.
The Multiplication of Force by a Hydraulic System
In this animated and interactive object, learners examine a depiction of how force is multiplied by a larger cylinder when pressure from a pump is applied to a smaller cylinder. A short quiz completes the activity.
Pascal's Law and Hydraulics
Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.
The Hydraulic System
Examine the components of a hydraulic system.
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.
By Terry Bartelt, Stephen Schneider
In this animated activity, learners examine how cavitation occurs in a hydraulic pump. A video clip is included. Learners then test their knowledge in a brief quiz.
