Ultrasonic frequencies are above the human audio range — higher than 20 kHz. Operating in the ultrasonic frequency range, ultrasonic sensors are commonly used for measuring proximity (distance), ...

Factory automation applications use a large number of retroreflective sensors and diffuse mode sensors. Sensors like these operate indirectly in that they detect and evaluate reflected light. However, ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

Intelligent light grids take many forms and cover applications from simple to complex. Sizes range from a few inches to several feet, and resolutions from 2 to 100 mm. Automation light grids take many ...
