6. Selection Recommendations

• Measurement Requirements: Choose the 330703-000-060-10-02-00 for applications requiring an 0–8 mm displacement range and high-frequency vibration monitoring (up to 8 kHz).
• Environmental Conditions: Prioritize this model for installations with temperatures exceeding +150°C or high vibration (e.g., gas turbine exhaust zones).
• System Compatibility: Ensure your monitoring system supports -20 to 0 VDC analog inputs or integrates with Bentley’s 3500 Series for full diagnostic capabilities.
• Cable Length: The 1-meter system length is ideal for compact setups; consult Bentley’s catalog for longer cable options (e.g., 5-meter or 9-meter configurations).

7. Precautions

• Installation:
  • Align the probe with the target surface at a nominal air gap (typically 2.5 mm) using Bentley’s calibration tools to ensure accuracy.
  • Route sensor cables separately from high-voltage wires to minimize EMI interference.
• Calibration:
  • Perform initial calibration with a certified displacement fixture and repeat every 12 months or after system modifications.
• Maintenance:
  • Inspect the probe and cable for physical damage (e.g., abrasions, corrosion) during routine shutdowns, especially in high-vibration environments.
• Safety:
  • De-energize the system and follow lockout/tagout procedures before handling the sensor to prevent electrical hazards.
