Function Features

• Integral Cable for Simplified Deployment: The pre-fabricated 5-meter FEP-insulated cable eliminates the need for separate wiring and connectors, reducing installation time and minimizing signal loss points. The braided copper shielding ensures 95% EMI/RFI protection, maintaining signal integrity in high-noise industrial environments.
• Multi-Transducer Versatility: Compatible with Bently’s 3300 XL proximity, velocity, and acceleration transducers, eliminating the need for dedicated transmitters for different sensor types. This flexibility reduces inventory costs and simplifies system design for mixed-machinery setups.
• Industry-Standard 4-20 mA Output: Converts raw sensor data into a universally accepted 4-20 mA analog signal. The 4 mA “live zero” design distinguishes between no vibration (4 mA) and power failure (0 mA), preventing false alarms and ensuring reliable condition monitoring.
• Configurable for Diverse Applications: Users can adjust measurement ranges (displacement/velocity/acceleration) via DIP switches or Bently’s 3300 XL Configuration Software, adapting the transmitter to low-amplitude precision equipment (e.g., CNC mills) and high-vibration industrial pumps.
• Proactive Fault Monitoring: The built-in Form C fault relay triggers alerts for critical issues, including sensor signal loss, vibration overrange, power fluctuations, or internal transmitter faults. This enables maintenance teams to troubleshoot proactively, minimizing unplanned downtime.
• Robust Environmental Adaptability: The UL 94 V-0 flame-retardant housing and wide operating temperature range (-20 °C to +70 °C) make it suitable for harsh industrial environments, including chemical plants, refineries, and mining sites.
• Flexible Mounting Options: Supports both DIN rail and panel mount installations, adapting to diverse control cabinet layouts. Screw terminals accept a wide range of wire gauges, simplifying wiring for different industrial setups.
• Seamless System Integration: Mates directly with Bently 3300 XL monitoring racks and data loggers. It also integrates with third-party DCS (Siemens PCS 7, Emerson DeltaV), SCADA, and predictive maintenance platforms (IBM Maximo, GE Predix) via standard analog inputs.
• Voltage Fluctuation Tolerance: The 18-32 V DC supply range accommodates variations in industrial power systems, ensuring consistent performance in remote locations or facilities with unstable electrical grids.

Application Scenarios

• Power Generation (Turbines & Generators): Installed in control cabinets for steam, gas, and hydroelectric turbines. It processes signals from bearing vibration transducers, transmitting 4-20 mA data to DCS for real-time monitoring and trip logic activation to prevent rotor rubs or bearing failures.
• Oil & Gas (Refining & Offshore): Deployed in refineries, pipeline compressor stations, and offshore platforms. The integral cable simplifies installation in tight control cabinets, while chemical-resistant FEP insulation withstands exposure to hydrocarbons and solvents.
• Manufacturing (Automotive & Aerospace): Used in production lines for robotic assembly arms, stamping presses, and CNC machines. The configurable range adapts to low-vibration precision tools and high-vibration heavy machinery, ensuring comprehensive monitoring.
• Chemical & Pharmaceutical: Installed in reactor control rooms for agitators, centrifuges, and process pumps. The flame-retardant housing and fault monitoring comply with strict safety standards for handling hazardous materials.
• Mining & Minerals Processing: Deployed in crusher and grinding mill control cabinets. The robust EMI shielding and integral cable ensure reliable signal transmission in high-dust, high-vibration mining environments.
• Water & Wastewater Treatment: Used in pump stations and aeration systems. The 5-meter cable reaches remote pump sensors, while the IP40 rating protects the transmitter from dust and incidental moisture in treatment facilities.
• Marine & Naval Systems: Installed in ship engine control rooms. The wide voltage tolerance accommodates marine electrical system fluctuations, while the integral cable simplifies wiring in compact engine compartments.
• Food & Beverage: Deployed in processing plants for mixers, blenders, and packaging machinery. The compact DIN rail design fits in small control cabinets, and the IP20 front panel prevents dust ingress into sensitive electronics.
