Liquid-level sensing is used in consumer electronics appliances like washing machines to detect the detergent level. The sensor technology has progressed to such an extent that refrigerators can now ...
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 ...
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 ...
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 ...
To meet these needs, Elesa introduced two new products: the HSC capacitive level sensor, suitable for conductive liquids such as water and non-conductive liquids such as oil/diesel, and the HSO ...
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 ...
