Level sensors determine the level of liquids and fluidized solids, such as slurries and large amounts of powder that have an exposed upper surface. There are two primary kinds of level sensors: point ...

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 ...

In Part 1 of this article, we explained popular liquid-level sensing methods and their limitations. We also delved into why capacitive-sensing techniques are superior to traditional methods used for ...

While sensors and low power actuators occupy the lowliest level of an automation system, they often require a disproportionate amount of time and attention. Historically, each sensor added entailed ...
