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 ...

Here is a design concept for a cheap single point optical liquid sensor that can detect the presence or absence of certain colored liquids inside a transparent tube. It can be tailored to output a ...

Spanish researchers describe the design and development of a prototype liquid level sensor that exploits the changes in light transmittance in a plastic optical fiber cable. Dr Lomer and colleagues ...

ProSense GWR series liquid level sensors utilize guided wave radar sensing technology to provide accurate, cost-effective liquid level measurement for industrial applications. These units provide ...

What are the key factors in optimizing mean time between failure (MTBF)? Developing the best strategy for MTBF. What to look for in MTBF test studies. For designers of engineered electronics powering ...
