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 ...

Controlling light with light is a long-sought goal for computing and communication technologies. Achieving this capability would allow optical signals to be processed without converting them into ...

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 ...

The company’s optical liquid-level switches are made with flat glass, which eliminates contamination problems associated with the 90-degree cone normally used in these types of switches and provides a ...

SST Sensing has partnered with Sparkfun to develop a simple to implement solution for single point liquid detection using infrared technology. The solution comprises an Optomax Digital liquid level ...

Miniature ultrasonic liquid level switches detect liquid levels in space-constrained applications, such as fluid storage tanks, compressors, boiler tanks, hydraulic reservoirs and chillers.

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 ...

Liquid-level switches used in aircraft, nuclear-power plants, medical equipment, and other critical applications must be precise and reliable. For that to happen, design engineers must know the ...
