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 ...

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 ...

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 ...

This reference design describes a cost-effective, low-power liquid-level measurement data acquisition system (DAS) that use a compensated silicon pressure sensor and a high-precision delta-sigma ADC.

Hydrostatic pressure produced by the water column at the bottom of the controlled liquid reservoir uses the trapped air in the measurement tube to produce the same amount of pressure on the sensor. At ...

A micrometer-sized liquid crystal droplet doped with fluorescent dye functions as a nanosecond optical switch that controls light output using light alone. The resonant cavity design cuts the energy ...

The new DULCOMETER diaLog C controller is designed for water treatment applications. The entry-level controller supports all of this company's sensors and ...

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 ...
