eddy-current sensor

eddy-current sensor

[′ed·ē ‚kə·rənt ′sen·sər]
(engineering)
A proximity sensor which uses an alternating magnetic field to create eddy currents in nearby objects, and then the currents are used to detect the presence of the objects.

The Eddy-Current sensor dimension is limited again by the size of the coils on the printed circuit board.
The eddy-current sensor is the most robust concept against external magnetic fields as a high frequent eddy current is induced and its impact analyzed - by this getting rid of low frequency components affecting the signal.
The most used technologies are magnetic sensors, eddy-current sensors and reluctance resolver.
Eddy-current sensors as well use a carrier frequency on the excitation side, resulting in the need of a demodulation before the angle can be derived from the arctangent calculation.
An integrated eddy-current sensor measures the distance of the sensor to the surface of the roll.
are also discussing the development of a remote field eddy-current sensor that could be integrated with the PLS 3000*.
Micro-Epsilon's EC5 combines a capacitive sensor with an eddy-current sensor in a single housing.
The popular sensors that are used in structural health monitoring and give instant information are the following: strain gauges, fibre optic sensors (FOS), eddy-current sensors, micro-electro-mechanical systems (MEMS) sensors, and piezoelectric sensors [19].
Ferraris eddy-current sensors include Type ACC 93 with a 1-kHz bandwidth and a 10-mV/g sensitivity when used with a 1-mm thick aluminum rotating disk or linearly moving sheet.
