Based on eddy current measurement principle, the eddy current sensors are specifically designed to measure distance and position of ferromagnetic and non-ferromagnetic materials. As eddy current sensors do not register non-conductive materials, such as dirt, oil and dust, they work especially well in harsh industrial environment. They also offer the high precision measurement with outstanding temperature stability. Featuring IP67 protective housing, the sensor can also withstand high pressure and temperature up to 2000 bar and 200C, respectively.
These compact and industrial-grade non contact displacement sensors from Micro Epsilon are capable for measuring dynamic tasks especially for monitoring oscillation and vibration with frequency response of up to 100kHz. With wide range of sensors available, eddy current sensors can be used in almost all measurement applications. The sensors can also be easily customized making them possible to be used in OEM and high volume manufacturing applications.
Eddy Current Measurement Principle
Eddy-Current sensors are designed based on electromagnetic induction and magnetic fields are created in and around the sensor and the target. The eddy current probe develops an alternating current in the sensing coil at the end of the probe which creates an alternating magnetic field with small induced currents in the target material; these currents are called eddy currents. The eddy currents create an opposing magnetic field which resists the field being generated by the probe coil. The interaction of the magnetic fields is dependent on the distance between the probe and the target. As the distance changes, the electronics integrated to the probes sense the change in the field interaction and produce a voltage output which is proportional to the change in distance between the eddy current sensor and target.
