PR6424/000-010 Emerson | 10-Meter Proximity Probe for DCS

Product Details

Product Overview

The Emerson Epro PR6424/000-010 is a high-precision Eddy Current Proximity Probe engineered for non-contact measurement of shaft vibration, axial displacement, and rotational position. As a critical sensor in the PR6424 family, it detects microscopic changes in the air gap between the probe tip and the rotating shaft. This specific variant features an extended 10-meter integrated cable, allowing for direct connection to CON series converters in remote junction boxes without the need for intermediate extension cables. It provides the essential raw signals required for machinery protection systems in high-speed turbines and compressors.

Part Number Breakdown: PR6424/000-010

• PR6424: 8mm Eddy Current Proximity Sensor Series.

• /000: Designates the standard mounting thread and sleeve configuration.

• -010: Indicates the 10-meter (10m) integrated coaxial cable length.

Engineering Advantages

• Extended Signal Reach: The integrated 10-meter cable eliminates the connector interface typically required at the 5-meter mark. By removing this connection point, the sensor reduces the risk of oil ingress and signal attenuation, which often occurs at intermediate junctions.

• Non-Contact Precision: This probe monitors shaft behavior without physical contact, preventing mechanical wear on critical components. It maintains high-resolution data acquisition even at extreme rotational speeds where contact sensors would fail.

• Extreme Thermal Durability: The probe tip survives constant exposure to temperatures reaching +180°C. This makes it ideal for installation near steam turbine bearings and high-pressure compressor stages.

• Noise-Resistant Coaxial Design: The specialized coaxial cable shields the high-frequency carrier signal from electromagnetic interference (EMI). This ensures that the raw signal remains pure before reaching the CON series converter.

• Hazardous Area Compliance: Full ATEX and CE certifications allow for legal and safe installation in explosive gas atmospheres, satisfying the safety protocols of the global oil, gas, and power industries.

FAQs

Q1: Is the Emerson PR6424/000-010 a new or refurbished unit?

A1: We provide only 100% brand new and original Emerson Epro sensors in factory-sealed packaging. Each unit comes with a full 12-month industrial warranty.

Q2: Can I use this probe with a Bently Nevada monitor?

A2: Proximity probes must match the electrical characteristics of the signal converter (driver). While the PR6424 is designed for Emerson Epro CON series converters, you should verify the voltage-to-displacement scaling ($mV/mm$) to ensure compatibility with third-party monitoring racks.

Q3: Does the 10m cable affect the calibration?

A3: No. The PR6424/000-010 is factory-calibrated specifically for its 10-meter cable length. You must use it as a complete unit; shortening the cable or adding extensions without recalibrating will result in measurement errors.

Q4: What is the benefit of the 8mm tip size?

A4: The 8mm tip offers a balanced measurement range (typically up to 2mm), providing enough clearance to prevent "probe-to-shaft" contact during high-vibration events while maintaining excellent sensitivity for small displacements.
