Description

BENTLY 330106-05-30-90-02-05(CN) 8 mm Eddy Current Proximity Probe

1. Product Description

• Non-Contact Sensing: Uses eddy current technology to avoid wear, critical for high-speed turbines and compressors.
• Customized for China: Includes a 3-meter (30) probe cable and 90° connector (90) for space-constrained installations common in Chinese industrial facilities.
• Extreme Temperature Tolerance: Operates at -51°C to +177°C (-60°F to +351°F), with cables rated for +260°C (+500°F) in high-heat applications like coal-fired boilers.
• 3500 System Compatibility: Direct integration with Bentley’s 3500 Monitoring System for real-time analytics and alarm triggering.

3. Advantages and Features

• Precision Engineering: <1% linearity error ensures early detection of misalignment (e.g., 0.05 mm deviations), reducing unplanned downtime by 30% in field tests.
• China-Specific Design: 90° connector minimizes installation space, while the 3-meter cable meets typical Chinese machinery layout requirements.
• Rugged Construction: Hermetically sealed stainless-steel probe (IP67) and FEP-insulated cables withstand dust, moisture, and EMI common in Chinese industrial zones.
• Cost-Effective Maintenance: Interchangeable components (probe/cable) eliminate bench calibration, saving 40% on maintenance costs vs. legacy sensors.

4. Application Areas and Case Study

Application Areas:

• Power Generation: Steam turbines, generators (e.g., 600 MW coal-fired units in China).
• Petrochemical: Centrifugal pumps, compressors in refineries.
• Manufacturing: High-speed spindles in automotive production lines.

Case Study:

5. Competitive Edge

• Temperature Range: Operates 20°C hotter than local alternatives, critical for China’s high-temperature industrial processes.
• Space Efficiency: 90° connector reduces installation depth by 50% vs. straight connectors, ideal for compact Chinese machinery.
• Local Compliance: Meets GB/T standards for EMI resistance, unlike some imported sensors requiring retrofitting.

6. Selection Recommendations

• Space Constraints: Choose the 90° connector variant if machinery access is limited (e.g., vertical pumps).
• Temperature: Opt for this model if your application exceeds +150°C (e.g., coker units in refineries).
• System Integration: Ensure compatibility with Bentley 3500 or Chinese DCS (e.g., Hollysys MACS) via 4–20 mA converters.
• Cable Length: Standard 3m suits most Chinese machinery; request custom lengths (e.g., 5m) for special layouts.

7. Precautions

• Installation:
  • Align the probe at 1.5 mm air gap using Bentley’s Chinese-calibrated feeler gauges.
  • Route cables away from high-voltage lines to prevent EMI (common in Chinese plants).
• Calibration:
  • Annual recalibration with Chinese NIM-certified tools (e.g., Shanghai Institute of Measurement and Testing).
• Environment:
  • Avoid direct steam exposure; use protective sleeves in wet environments (e.g., paper mills).
• Safety:
  • Follow GB 50174-2017 for electrical safety during installation in Chinese data centers or factories.
