Eddy Current Sensor Applications. The inductive measuring system is designed for applications in industrial processes. As it is compatible with more than 100 sensor models, versatile applications can be solved. The eddyNCDT 3070 eddy current system is designed for small measuring ranges below 1 mm. It offers high performance while being suitable for industrial and universal use. Eddy current sensors detect the distance or the change to metal objects without contact, dynamically and extremely accurately. The TX electronics which are specially adapted to the respective sensor calculate an analogue output signal proportional to the distance. In addition, there is a USB and CAN interface for reading the data. Eddy current sensors are primarily used for displacement and position measurement of electrically conductive targets. They are generally used for measuring ferromagnetic and non-ferromagnetic materials. They are suitable for applications in harsh industrial environments due to their superior tolerance for oil, dirt, dust, moisture and magnetic interference fields.
eddy current proximity sensor Formula. The target material must be at least three times thicker than the effective depth of the eddy currents to make the transducer successful because the transducer assumes that the eddy currents are localized near the surface of a semi-infinite solid and the actual eddy current amplitude decreases quadratically with distance. Furthermore eddy current sensors are perfectly suited for the observation of dynamic events. Eddy current sensors of the TX-Series stand out with an excellent dynamic range >100 kSa/s and resolutions in the sub-micron range. With this premise the eddy current sensor is suitable for general motion analysis and in automotive applications.

The eddy current sensor needs to be optimized for carbon materials. Different sensor types, such as absolute, differential and compensated sensors, can be used for single sensor probing. The single sensor configuration is a directional sensor with a high spatial resolution due to its high-focusing point-spread function (PSF) [ 8 ] [ 9 ]. History. Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by François Arago in 1824, but French physicist Léon Foucault is credited with discovering them in 1855. ECT began largely as a result of the English scientist Michael Faraday's discovery of electromagnetic induction in 1831. Vacuum applications have certain considerations when using eddy-current sensors. Learn more from our technical library.. Eddy-Current Sensor TechNote LT02-0021.. The epoxy in the probes has been specifically tested for vacuum applications requiring low outgassing. Probe cabling uses a PTFE jacket which is highly stable and produces very. Kaman specializes in inductive, eddy current technology. Our sensors provide non-contact indication of linear position/displacement by outputting an analog voltage, or, in some cases, a current that is proportional to the distance between the sensor face and the target being sensed. Eddy current technology requires an electrically conductive target. It does not need to be […]
