Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

When applied to pharmaceuticals, the term “off-label” suggests the (frequently discovered) practical and beneficial uses for a drug that are different from the one it was originally developed for.

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 ...

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 ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

The need for accurate and reliable level measurement systems is increased by the demands of advanced automated processing systems, more stringent process control and strict regulatory requirements. By ...
