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. In a petrochemical plant, the module can monitor the vibration of centrifugal pumps, alerting operators to potential seal failures before they cause leaks.
   • Integrates with emergency shutdown systems (ESD) in offshore platforms, ensuring safety during extreme operational conditions. The module’s rugged design makes it suitable for harsh marine environments, where exposure to saltwater and high winds is constant.
2. Power Generation:
   • Analyzes vibration in steam turbines and generators to optimize performance and prevent stator-rotor contact in power plants. For a combined cycle power plant, the module can monitor both the gas and steam turbines, ensuring they operate within safe vibration limits to maximize energy efficiency.
   • Supports condition-based maintenance programs by providing real-time data on rotor dynamics, enabling scheduled repairs to minimize downtime. By analyzing vibration trends, maintenance teams can predict when components like bearings will need replacement, reducing unplanned outages.
3. Manufacturing:
   • Controls vibration in high-speed packaging machinery and robotic arms, enhancing product quality and reducing production losses in automotive and pharmaceutical plants. In a car assembly line, the module can monitor the vibration of robotic welders, ensuring consistent weld quality and preventing costly rework.
   • Monitors motor bearings in conveyor systems to predict maintenance needs, improving overall equipment effectiveness (OEE). By detecting increased vibration in conveyor motors, manufacturers can schedule bearing replacements during planned downtime, avoiding production interruptions.
4. Water/Wastewater Treatment:
   • Ensures reliable operation of centrifugal pumps by detecting imbalance or misalignment, maintaining consistent water flow in treatment facilities. In a wastewater plant, the module can monitor the vibration of aeration blowers, ensuring they operate efficiently to maintain proper oxygen levels in treatment tanks.
   • Integrates with SCADA systems for remote monitoring of distributed pump stations, enabling proactive maintenance scheduling. Operators can access vibration data from multiple sites, prioritizing maintenance based on real-time equipment health metrics.

Installation and Maintenance

• Verify the power supply meets 24 VDC ±10% and that the control rack is properly grounded to prevent electrostatic discharge (ESD). Use a multimeter to confirm voltage stability before connecting the module to avoid damage from power fluctuations.
• Use BENTLY’s configuration software to define input channel types (proximity probe or accelerometer) and set initial alarm thresholds based on machinery specifications. For example, if monitoring a steam turbine, configure the channels to accept signals from proximity probes measuring shaft displacement.
• Mount the module in a 19″ rack with at least 50 mm of clearance for airflow, securing it with the provided brackets to minimize vibration-induced displacement. Ensure the rack is located in an environment within the module’s operating temperature range (-25°C to +60°C).

• Routine Inspections: Monthly visual checks of front-panel LEDs (green for normal operation, red for faults) and cleaning of dust from ventilation slots to maintain optimal cooling. Use a soft, non-conductive brush to remove debris without damaging internal components.
• Calibration: Annual calibration of input channels using a BENTLY-certified vibration calibrator to ensure measurement accuracy. This involves applying known vibration levels and verifying output signals against standards, ensuring the module continues to provide reliable data.
• Firmware Updates: Periodically update the module’s firmware via BENTLY’s software to access new diagnostic features and compatibility improvements, particularly when integrating with newer system versions. Outdated firmware may lack support for advanced vibration analysis algorithms.
• System Testing: Biannual functional tests of alarm relays and communication protocols to ensure compliance with safety standards. Simulate vibration conditions to verify alarm triggers and data transmission reliability, ensuring the module responds correctly to potential equipment issues.
