Eddy Current Probes and Drivers
Proximity sensors work on the eddy current principle. A proximity system consists of an eddy current probe, extension cable and driver. A high-frequency RF signal is generated by the driver, sent through the extension and probe cables and radiated from the probe tip.
The tip consists of a precision wound copper coil
inside a chemical and temperature resistant PEEK case. The tip is either mounted
on a threaded stainless steel rod allowing easy gap adjustment on a bracket via
two locking nuts or a flat, low profile mount. The driver demodulates the
signal, amplifies and linearises it to provide an output proportional to the
probe to target gap and/or vibration of the target.
Eddy currents are generated in the surface of the
target which modify this signal. The driver demodulates the signal, amplifies
and linearises it to provide an output proportional to the probe to target gap
and/or vibration of the target.
