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 ...

As sailors in the 17th century learned the hard way, having an accurate clock for navigation is pointless if it is too delicate to carry aboard ship. The same goes for the super accurate optical ...

To meet these needs, Elesa introduced two new products: the HSC capacitive level sensor, suitable for conductive liquids such as water and non-conductive liquids such as oil/diesel, and the HSO ...

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, ...

The optical level sensor FFAR is a robust measuring device in a stainless steel housing that detects level via infrared light and is therefore able to identify various non-conductive liquids. It is ...

A research team has developed a new way to measure and predict how plant leaves scatter and reflect light, revealing that ...

An optical Illusion is a visual trick where our eyes and brain perceive different images from reality. These illusions are a type of visual puzzle that creates a misleading effect on our brain, ...

An optical illusion is a visual phenomenon where the brain misinterprets what the eyes perceive, creating a false or misleading impression of reality. This occurs because the brain processes visual ...
