Compatible Systems & Accessories

The EPRO PR6423/00R-031 integrates seamlessly with critical monitoring infrastructure:

MMS 6000 Protection Systems: Designed for turbine monitoring, this sensor pairs with modules like MMS6210 to provide real-time data on rotor dynamics.

CON021 Interface: Use the EPRO PR6423/00R-031 with CON021-compatible preamplifiers for signal conditioning and noise reduction, ensuring accurate measurements in high-electromagnetic-interference environments.

Typical Applications

The EPRO PR6423/00R-031 excels in diverse industrial scenarios:

Axial Displacement Monitoring: In power plants, it detects micron-level shifts in turbine shafts to prevent catastrophic rotor-stator collisions.

Bearing Health Assessment: For oil and gas compressors, the EPRO PR6423/00R-031 measures bearing wear and oil film thickness, enabling predictive maintenance and reducing unplanned downtime.

Installation & Maintenance Guidelines

Optimize performance with proper handling of the EPRO PR6423/00R-031:

Mounting: Secure the sensor using M10×1 or 3/8”-24-UNF-2A threads, ensuring a nominal gap of 1.5 mm (±0.2 mm) from the target surface. Calibrate using the factory-set linearity (pre-configured for 42CrMo4 steel) to achieve a -12 VDC output at the midpoint.

Troubleshooting: Regularly inspect cable integrity and connector seals. If signal drift occurs, verify the gap voltage and recalibrate using CON021-compatible test equipment. Replace worn cables or damaged LEMO connectors to maintain IP67-rated protection.
