In this animated object, learners examine the factors that determine how well a capacitive proximity sensor can detect an object. Those factors include size, position, and the materials from which the target is made. A brief quiz completes the activity.
Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.
Learners study animations to see the connection between temperature and resistance as they examine the operation of an RTD. A table is used to convert resistance readings to the corresponding temperatures. A brief quiz completes the activity.
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.
Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.
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.
Learners examine how a linear displacement transducer is used to measure the linear position of a physical object. Animations show the sequential steps of the entire operation.
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.
In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.
This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
