Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

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 ...

EGE-Elektronik has revised its intrinsically safe optical level sensors for liquids with ATEX/IECEx approval for use in Zone 0 and is launching the new, improved UF2 series. Featuring a glass tip, ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.
