Origin: Germany

 

Brand: EPRO

 

Based on the eddy current effect. The sensor coil generates an alternating magnetic field by passing alternating current. When it approaches the metal object being measured, eddy currents are generated on the metal surface, which in turn generate secondary magnetic fields that react with the sensor coil, causing changes in parameters such as inductance, impedance, and quality factor. By measuring these parameter changes, physical quantities such as displacement and vibration of the measured object can be indirectly measured.

Product Features
Non contact measurement: It does not come into contact with the object being measured, avoiding interference with the object and affecting measurement accuracy due to wear and tear. It is suitable for high-speed rotation and high-precision measurement occasions.
High precision: capable of accurately measuring small displacements and vibration changes, with measurement accuracy reaching micrometer level or even higher.
High reliability: Adopting advanced electronic technology and manufacturing processes, it has good stability and anti-interference ability, and can operate reliably in harsh industrial environments for a long time.
Multiple measurement functions: capable of measuring various physical quantities such as the gap between rotating and fixed parts, shaft eccentricity, shaft bending, bearing wear, oil film thickness, and relative thermal expansion between the shaft and bearings.
Application areas: Widely used for monitoring and protection of various industrial equipment such as turbomachinery, fans, compressors, gearboxes, water pumps, etc. It can also be used for laboratory research and teaching, such as measuring shaft vibration, displacement and other parameters in the monitoring and protection system of rotating machinery such as steam turbines, water turbines, generators, etc., providing a basis for equipment fault diagnosis and maintenance.
