Emerson EPRO PR6423 Proximity Sensor

Feature & Principle

It is a non-contact eddy current proximity sensor of EPRO series. The probe head generates high-frequency alternating magnetic field. When the metal rotating shaft approaches the probe, eddy current will be induced on the metal surface. The change of gap distance will cause the impedance change of the probe coil. The supporting preamplifier converts the impedance signal into standard voltage output signal. It can continuously collect shaft vibration and thrust displacement data, not affected by oil film, steam and medium temperature, and is widely used for rotating machinery online protection and condition monitoring.
