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 ...

Sensortechnics’ new CLC capacitive level sensor continuously measures the fill level of liquids as well as granular or pulverized materials. The miniature sensor can be easily mounted to the outside ...

The non-invasive design, with no contact between the sensor and the fluid, eliminates all media compatibility and sterility issues. The device is highly flexible and the user can easily calibrate the ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

This article presents a users guide to level-measurement technology for the water and wastewater treatment industry, whether that may be the instrumentation for open channel flow or level measurement.

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...
