6. Selection Recommendations

• Equipment Type: Choose the 1900/65A-00-00-01-00-00 for single-point monitoring of low to medium-speed machinery (up to 8,000 RPM), such as fans or small pumps. For multi-point or high-speed applications, consider dual-channel models like the 1900/65A-00-00-02-00-01.
• Environmental Factors: Prioritize this model for installations with moderate vibration (≤5g) and temperature fluctuations, as its compact design balances cost and resilience.
• System Requirements: Ensure your control system accepts 4–20 mA analog inputs; for digital communication, inquire about optional upgrade kits (not included in this model).
• Budget Constraints: Ideal for projects requiring basic vibration monitoring without advanced analytics, offering a cost-efficient entry into predictive maintenance.

7. Precautions

• Installation:
  • Mount the module away from high-voltage cables to minimize EMI; use shielded twisted-pair cables for sensor connections to maintain signal integrity.
  • Align sensors perpendicular to the machinery surface and calibrate using a vibration shaker to establish accurate baseline readings.
• Configuration:
  • Set vibration thresholds according to ISO 1940 (bearing vibration standards) or the equipment manufacturer’s guidelines to avoid false alarms.
  • Verify the 4–20 mA output range during commissioning to ensure compatibility with your PLC/DCS input settings.
• Maintenance:
  • Regularly inspect the module’s LED indicators for power and signal status, and clean dust or debris from ventilation slots in high-dust environments.
  • Replace the module every 10 years or after exposure to extreme conditions to maintain measurement accuracy.
• Safety:
  • Power down the system before installing or servicing the module to prevent electrical hazards.
  • In hazardous environments, use approved explosion-proof enclosures and follow local safety standards (e.g., NEC Class I, Division 2).
