And, capacitive displacement sensors are even found in disk drives. These sensors produce an output: capacitance. Measuring this capacitance is an inherently analog problem that can be very tricky.

The brochure on capacitive nanometrology displacement sensors and electronics presents PI’s state-of-the-art systems and also features a tutorial on single plate and dual plate capacitive sensors and ...

Sensor manufacturer Micro-Epsilon UK has just launched a new range of non-contact, wear-free capacitive displacement measurement sensors, which offer extremely high performance (resolution and speed), ...

Eddy current or capacitive displacement sensors use magnetic field to measure vibrations.An AC powered probe generates a magnetic field. This field induces a filed in test object, so it must be ...

Other than a few exceptions, such as pressure sensors, all capacitive sensors use changes in the plate surface or the dielectric to measure changes in capacitance. Most sensors can be divided into two ...

Two sensor plates – a target and a probe – form a parallel-plate capacitor, with the spacing of the plates measured using an electronic controller. Measurement ranges from 20 µm to 1250 µm are ...
