Product Overview

Technical Specifications

Main Features and Advantages

Application Areas

1. Oil and Gas:
   • Monitors compressors and pumps in refineries and pipeline networks, detecting early signs of cavitation or bearing wear to prevent unplanned shutdowns.
   • Integrates with emergency shutdown systems (ESD) in offshore platforms, ensuring safety during extreme operational conditions.
2. Power Generation:
   • Analyzes shaft displacement in steam turbines and generators to optimize performance and prevent stator-rotor contact in power plants.
   • Supports condition-based maintenance by providing real-time data on rotor dynamics, enabling scheduled repairs to minimize downtime.
3. Manufacturing:
   • Controls vibration in high-speed packaging machinery and robotic arms, enhancing product quality and reducing production losses in automotive and pharmaceutical plants.
   • Monitors motor bearings in conveyor systems to predict maintenance needs, improving overall equipment effectiveness (OEE).
4. Water/Wastewater Treatment:
   • Ensures reliable operation of centrifugal pumps by detecting imbalance or misalignment, maintaining consistent water flow in treatment facilities.
   • Integrates with SCADA systems for remote monitoring of pump stations, enabling proactive maintenance scheduling.

Installation and Maintenance

• Verify the probe’s measurement range (0–2500 μm) matches the application and use BENTLY’s installation tools to set the initial gap (typically 1.5 mm) between the probe and target surface.
• Route the 5 m cable away from high-voltage lines to minimize EMI, securing it with stainless-steel clamps to prevent movement-induced damage.
• Ensure the mounting bracket allows precise alignment with the shaft, using a dial indicator to confirm perpendicular installation.

• Routine Inspections: Quarterly visual checks for cable abrasion, connector corrosion, and probe alignment, especially in high-vibration environments. Replace damaged cables immediately to avoid measurement errors.
• Calibration: Annual calibration using a BENTLY 3300 System Calibrator to ensure sensitivity (7.87 V/mm) and linearity, adjusting for any drift in performance.
• Environmental Monitoring: Regularly assess ambient temperature and humidity levels to ensure they remain within the probe’s operational range (-54°C to +177°C).
• Spare Parts Management: Keep a spare BENTLY 330108-91-05 on hand for critical systems, as its hot-swappable design allows replacement without shutting down machinery.
