PLCs, Power Supplies & Others

The EPRO PR6423/297-110 is a precision eddy current displacement sensor for industrial machinery monitoring. This sensor non-invasively measures the distance or vibration of conductive targets like rotating shafts. Moreover, it provides reliable data essential for predictive maintenance and equipment protection systems.

Non-Contact Measurement Principle and Application

This sensor generates a high-frequency electromagnetic field from its active probe tip. When a conductive target enters this field, it induces eddy currents that change the sensor’s impedance. Consequently, the system can precisely calculate the gap distance or dynamic vibration of the target.

System Integration for Machinery Protection

The EPRO PR6423/297-110 is critical for monitoring radial shaft displacement, vibration, and eccentricity in turbines, compressors, and pumps. It connects directly to compatible monitoring systems like the EPRO MMS 6000. This sensor is a key component in comprehensive protection schemes that may also include speed monitoring and trip devices. For instance, it works alongside protective relays like the RMS-TSG-TZ-C Static Trip unit within a complete machinery train. The data it provides is often processed by system controllers such as the IS200AEBMG1AFB.
