The EPRO PR6423/01C-010 is an 8mm eddy current sensor with a signal converter from Emerson Epro. It is specifically designed for critical applications in turbomachinery, including steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans. The sensor is used to measure radial and axial shaft dynamic displacement, position, eccentricity, and speed..Non-contact sensor designed for critical turbomachinery applications such as steam, gas and hydro turbines, compressors, gearboxes, pumps and fans to measure radial and axial shaft dynamic displacement; position, eccentricity and speed.Click the file（pr6423-8mm-sensor） below to learn more about the configuration:

The eddy current sensor and the preamplifier form an oscillator, and the amplitude attenuates as the sensor probe approaches the metal object being measured. The amplitude of the attenuation is proportional to the distance between the sensor and the object being measured. The sensor and preamplifier have been linearly calibrated using calibration material 42CrMo4 before leaving the factory, so there is no need for further calibration during installation. The user only needs to adjust the air gap between the sensor and the measuring surface until the desired signal is obtained from the output of the front sensor.

The working principle of the German EPRO sensor: The vibration sensors PR926 and PR9268 consist of a seismic block and a measuring coil supported by a spring plate. The measuring element can move within the magnetic field of a circular * magnet. The natural frequency of the sensor is between 4-13H2, depending on the different sensor models. The vibration of the sensor casing will generate a voltage signal proportional to the vibration speed. The PR9258… series sensors can only have one measurement direction (vertical or horizontal). PR 9266/ The series sensors have a lifting coil that can be used for both vertical and horizontal measurements.
