EPRO PR6424/014-040

Description

Product Description

The EPRO PR6424/014-040 is a high-performance, non-contact eddy current proximity transducer system from the renowned EPRO GmbH (now part of Baker Hughes). This specific model is a fundamental component for condition monitoring and protection in critical rotating machinery. The EPRO PR6424/014-040 system consists of a transducer (probe), an extension cable, and a proximitor (driver), working together to measure the relative vibration and axial position of a shaft with exceptional accuracy and reliability. It is engineered to convert the distance between the probe tip and the observed metallic surface (typically a shaft) into a precise, proportional DC voltage signal. This makes the EPRO PR6424/014-040 an indispensable tool for predictive maintenance, avoiding unplanned downtime in industries where machine failure is costly.

Product Parameters

• Measurement Principle: Eddy Current / Inductive

• Measured Variable: Relative Vibration and Position (Displacement)

• Nominal Sensitivity: Typically -8 mV/µm (e.g., 200 mV/mil), system-dependent

• Linear Range: Defined by probe and proximitor combination; standard ranges include 0-2 mm or 0-80 mils.

• Frequency Response: 0 to 10 kHz (-3 dB), suitable for capturing both slow roll and high-frequency vibration events.

• Output Signal: -1 to -21 V DC (linear within measuring range), corresponding to the gap between probe and target.

• Target Material: Electrically conductive materials, typically steel. Requires calibration for other materials.

• Operating Temperature (Probe): Up to 150°C (302°F) for standard versions, with high-temperature models available.

• Power Supply: Typically -24 V DC from the associated proximitor (e.g., CON 010 or PR 6426 series).

• System Compatibility: Designed to interface seamlessly with EPRO’s own monitoring systems (MMS 6000, MMS 3000) and most other PLC or DCS protection subsystems via its standardized voltage output.

Advantages and Features

• Extreme Robustness: The EPRO PR6424/014-040 probe is designed for long-term stability in harsh industrial environments, resistant to oil, pressure, and steam.

• High Reliability and Accuracy: Provides a stable, repeatable measurement signal critical for trustworthy machine protection decisions.

• Intrinsic Safety: The system can be configured for use in hazardous areas with appropriate barriers.

• Temperature Stability: Excellent compensation for temperature drift, ensuring consistent readings despite ambient changes.

• Global Proven Standard: As part of the EPRO PR 64xx series, this model is an industry-standard technology specified by OEMs and end-users worldwide for turbomachinery.

• Integrated System Approach: When used with genuine EPRO cables and proximitors, it guarantees specified performance, eliminating calibration uncertainties from mixed-brand setups.

Application Cases in Application Fields

• Power Generation: Continuous vibration monitoring on steam and gas turbine shafts, generator bearings, and feedwater pumps in nuclear and fossil-fuel plants.

• Oil & Gas: Protection of critical compressors (centrifugal, reciprocating) and gas/steam turbines on offshore platforms and pipelines.

• Petrochemical & Refining: Monitoring large compressor trains in catalytic cracking and other process units to prevent catastrophic failure.

• Marine Industry: Condition monitoring of main propulsion turbines and gearboxes on large vessels.

• Heavy Industry: Protecting motors, fans, and blowers in metallurgy, cement, and paper production.

Comparisons with Competing Products

Compared to other eddy current systems like Bently Nevada 3300 XL series or Vibro-Meter VK-101 systems, the EPRO PR6424/014-040 holds its ground:

• Brand Heritage: EPRO is equally prestigious in the European and global power markets, often specified alongside Bently Nevada.

• Standardization: While Bently Nevada’s 5 mV/mil and 8 mV/mil are common in the Americas, EPRO’s -8 mV/µm is a dominant standard in many international markets and OEM specifications.

• System Philosophy: EPRO systems are often noted for their straightforward calibration and robust construction. The competition may offer wider accessory or form-factor options.

• Interfacing: All major systems provide compatible voltage outputs for PLC/DCS, but the physical connectors and cable types differ, making them non-interchangeable without adapters.

Selection Suggestions and Precautions

1. Confirm System Requirements: Always verify the required sensitivity (mV/µm or mV/mil), linear range, and connector type specified by your machinery OEM or existing monitoring system.

2. Complete System Needed: Remember that the EPRO PR6424/014-040 transducer requires a matching extension cable (e.g., PR 6424/0-0) and a compatible proximitor (e.g., CON 010, PR 6426). Never mix probes and cables from different brands without verifying compatibility.

3. Target Material: Critical. The system is calibrated for standard steel (AISI 4140). If your shaft is made of a different material (e.g., stainless steel, monel), the sensitivity and linear range will change, and recalibration is necessary.

4. Environment: Check the ambient temperature. For installations near high-temperature casings (above 150°C), consider a high-temperature probe version.

5. Installation: Proper probe mounting (gap setting, securing, cable routing) is crucial. Use a digital micrometer for precise initial gap (standoff) setting as per the datasheet. Ensure the measurement area on the shaft is clean, concentric, and free of scratches or magnetism.
