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 ...

This digital optical liquid-level sensor is said to be versatile enough to be mounted at any angle and at the top, sides, or bottom of a vessel. Measuring just 30.25 mm x 19 mm, the sensor houses an ...

Sensortechnics has introduced a new OLP series of miniature optical liquid level switches. These cost-effective point level sensors measure the presence or absence of liquid in a wide range of OEM ...

In contemporary dialysis instruments designed for hemodiafiltration, hemofiltration and hemodialysis, a variety of sensors are employed, allowing the monitoring of liquid level, flow and pressure in ...

There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...
