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 ...

New research has shown how the quantum mechanical principle of strong coupling opens unrivalled possibilities for designing optical filters. A team of researchers from the University of Cologne, ...

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 ...

A team of researchers from the University of Cologne, Hasselt University (Belgium) and the University of St Andrews (Scotland) has succeeded in using the quantum mechanical principle of strong ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

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 ...
