Function Features

• Acceleration-Optimized Signal Processing: Enhanced hardware includes a high-bandwidth charge amplifier and specialized firmware, delivering ±0.15% accuracy across 5 Hz–20,000 Hz—critical for detecting high-frequency faults like bearing rolling element fatigue, gear tooth impact, and resonant vibrations. This outperforms standard modules in capturing subtle, high-speed anomalies that precede machinery failure.
• Built-In Charge Amplifier: The integrated, gain-adjustable charge amplifier allows direct connection to piezoelectric acceleration sensors, eliminating the need for external signal conditioning equipment. This reduces installation complexity, minimizes signal loss, and lowers overall system costs compared to setups requiring separate amplifiers.
• Single-Channel Targeted Monitoring: Dedicated single-channel design focuses processing power on critical high-speed components (e.g., turbine blades, motor bearings, gearbox pinions), avoiding cross-channel interference. Ideal for retrofitting into existing 3500 systems where specific assets demand precise acceleration monitoring without full system upgrades.
• Multi-Parameter Measurement Flexibility: While optimized for acceleration, users can switch between acceleration, velocity, and displacement via front-panel DIP switches. This adaptability supports diverse applications—using acceleration for high-speed motors, velocity for pumps, and displacement for slow-speed shafts—reducing inventory of specialized modules.
• Dual Isolated Analog Outputs: Two independent 4–20 mA outputs provide redundant signal transmission to primary DCS and secondary monitoring systems. Galvanic isolation prevents ground loops and signal corruption, essential for safety-critical applications like aerospace test stands and power generation turbines.
• Dual Status Outputs for Precise Alerts: Separate dry contacts for sensor faults and acceleration threshold alerts enable granular troubleshooting. The acceleration threshold can be configured to trigger warnings at user-defined levels (e.g., 90% of manufacturer’s fatigue limits), allowing proactive maintenance before component failure.
• Advanced EMI/RFI Shielding: Module-level EMI filtering, shielded input terminals, and twisted-pair signal paths protect against electromagnetic interference from high-frequency drives, radar systems, and industrial communication networks. This ensures stable measurements in electrically noisy environments like automotive assembly lines and aerospace facilities.
• Seamless 3500 System Integration: Designed to slot into Bently’s 3500 chassis, the module integrates with 3500 display modules, alarm logic solvers, and communication modules (Ethernet/Modbus). This modularity allows scaling from single-point monitoring to full machinery protection systems, leveraging existing infrastructure and reducing capital expenditure.
• Extreme Environment Durability: -40 °C to +70 °C temperature range and robust shock/vibration resistance enable reliable operation in arctic aerospace test facilities, desert power plants, and high-vibration manufacturing lines. The module maintains calibration and performance in conditions that degrade standard monitoring devices.
• User-Friendly On-Site Configuration: Front-panel DIP switches for range selection, parameter switching, and gain adjustment, paired with LED indicators (power, signal, fault, threshold alert), enable on-site setup without specialized software. Technicians can reconfigure the module in minutes, minimizing downtime during maintenance or asset changes.
