Product Overview: Epro PR6423/000-000+CON011

The Epro PR6423/000-000+CON011 is a premium-quality eddy current proximity sensor designed for continuous, precise, and reliable monitoring of critical rotating machinery. Developed by Epro, a respected brand under Brüel & Kjær Vibro, this sensor-transducer combination is part of the PR6423 series and is primarily used for non-contact displacement measurement.

The sensor is widely implemented in condition monitoring systems, especially in turbines, compressors, pumps, and other rotating equipment. It plays a key role in detecting shaft vibrations and axial displacement, contributing significantly to predictive maintenance strategies in industrial environments.

The sensor (PR6423) and converter (CON011) are engineered to provide a high level of accuracy and resistance to environmental interferences such as temperature fluctuations, electromagnetic interference, and vibration, ensuring consistent and long-term operation.

Installation Instructions

1. Preparation:

   • Verify that the installation area is clean and free from metal particles or dust.

   • Confirm that the sensor thread (e.g., M14x1.5) matches the machine’s probe port.

2. Mounting the Sensor:

   • Carefully screw the PR6423 sensor into the mounting hole until the specified distance from the shaft is achieved.

   • Use a feeler gauge to adjust the gap between the sensor tip and the shaft. The typical initial gap is 1 mm (±0.1 mm).

3. Cable Connection:

   • Connect the sensor cable to the CON011 converter.

   • Ensure secure connections to prevent signal loss or electromagnetic interference.

4. Converter Setup:

   • Mount the CON011 converter in a control cabinet or junction box.

   • Provide power supply of ±15V DC.

   • Connect the output terminals to the data acquisition or control system.

5. Testing and Calibration:

   • Power the system and check signal integrity.

   • Adjust zero and span settings if required.

   • Validate system functionality using a test signal or reference movement.

6. Maintenance:

   • Periodically inspect the sensor for contamination or mechanical damage.

   • Verify connector integrity and cable insulation.
