Origin: Germany

 

Brand: EPRO

 

Based on the eddy current effect, the coil of the sensor generates an alternating magnetic field by passing an alternating current. When the measured conductive metal object approaches, eddy currents are generated on the surface of the object. The reverse magnetic field generated by the eddy currents affects the original coil magnetic field, causing changes in coil impedance. By measuring the impedance changes of the coil, parameters such as the distance between the object and the sensor can be obtained, thus achieving the measurement of physical quantities such as displacement and vibration.

Product Features
Non contact measurement: avoids wear and interference on the measured object, and can be used in situations where high accuracy is required and the surface of the measured object is not easy to contact.
High precision: able to accurately measure parameters such as small displacements, providing accurate data for monitoring the operation status of equipment.
Good stability: Strong anti-interference ability, able to work stably in complex electromagnetic environments and different temperature conditions.
Multiple configurations: available in various thread lengths, cable forms, and other configurations to meet different installation and measurement needs.


application area 
It can measure shaft vibration, shaft displacement, clearance between rotating and fixed parts, shaft bending, bearing wear, oil film thickness, relative thermal expansion between shaft and bearing, thermal expansion of bearing, valve position, etc. It is widely used in the operation status monitoring and fault diagnosis of various rotating equipment such as turbomachinery, and plays an important role in industrial fields such as petroleum, power, chemical, metallurgy, etc.
