Capacitive sensing and imaging techniques have emerged as versatile and high‐resolution tools in the field of non‐destructive evaluation (NDE). By detecting variations in dielectric properties, these ...

This application note shows how to use a PICmicro® microcontroller and minimal external circuitry to detect small capacitances. The design is based on an operational amplifier (op amp) integrator. A ...

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 ...

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 ...

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 ...

This file type includes high resolution graphics and schematics. Capacitive sensors are common in today’s consumer electronics, since they are used in many touchscreen applications. Most of the ...

In the past, capacitive sensors for automotive electronics were rarely used, as they were deemed to be hard to control, difficult to read out, sensitive to aging, and temperature dependent. On the ...

Carlo Gavazzi is excited to introduce three new series of M12 Capacitive Sensors with IO-Link Communications. Based on our 4th generation TRIPLESHIELDTM sensors, these CA12 Series Sensors represent ...
