Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

Figure 7 provides the typical design flow for implementing capacitive sensing. Firmware (F/W) Development, Tuning, and Production Fine Tuning are the critical phases in the life cycle of a ...

Described as being immune to noise and easy to deploy, the flat-pack BCF10 capacitive sensor for level applications has the ability to detect liquids with high concentrations of chlorides such as ...

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 ...

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 ...

Compact, economic and quick to install, SICK’s CQF16 capacitive level sensor has been developed to provide a universal, non-contact solution wherever the fill level of water-based liquids must be ...

Non-contact displacement measurements can be made rapidly and with high precision using capacitive sensors over a modest range. The main features are: Capacitive sensing is a non-contact measurement ...
