Function Features

• Multi-Transducer Compatibility: Designed to work seamlessly with Bently Nevada’s 3300 XL proximity, velocity, and acceleration transducers, eliminating the need for dedicated transmitters for different sensor types. This flexibility simplifies system design and reduces inventory costs.
• Industry-Standard 4-20 mA Output: Converts raw sensor signals into a stable 4-20 mA analog output—universally accepted in industrial control systems. The 4 mA “live zero” ensures distinction between no vibration (4 mA) and power failure (0 mA), preventing false alarms.
• Configurable Measurement Ranges: Users can adjust the transmitter’s output range via DIP switches or software (Bently Nevada 3300 XL Configuration Tool) to match specific machinery requirements, from low-amplitude precision equipment to high-vibration industrial pumps.
• Built-In Diagnostics & Fault Monitoring: The Form C fault relay triggers alerts for critical issues such as sensor signal loss, overrange vibration, power supply fluctuations, or internal transmitter faults. This enables proactive troubleshooting and minimizes unplanned downtime.
• Robust EMI/RFI Shielding: Complies with stringent IEC electromagnetic compatibility (EMC) standards, ensuring reliable performance in high-noise industrial environments (e.g., near large motors, generators, or power cables). The shielded housing and differential input design reject interference.
• Flexible Mounting & Termination: 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 and reducing installation time.
• Wide Operating Voltage Range: The 18-32 V DC supply tolerance accommodates variations in industrial power systems, ensuring consistent performance even during voltage fluctuations common in manufacturing or remote locations.
• Flame-Retardant Housing: The UL 94 V-0 rated polycarbonate housing provides fire safety, making it suitable for hazardous industrial environments (e.g., oil refineries, chemical plants) where flammable vapors may be present.
• Seamless System Integration: Interfaces directly with Bently 3300 XL monitoring racks and data acquisition systems. It also integrates with third-party DCS (e.g., Siemens PCS 7, Emerson DeltaV), SCADA, and predictive maintenance software via standard analog inputs.

Application Scenarios

• Power Generation (Thermal & Nuclear): Installed in control cabinets for steam turbines, gas turbines, and generators. It processes signals from bearing vibration transducers, transmitting calibrated 4-20 mA data to DCS for real-time monitoring and trip logic activation.
• Oil & Gas (Refining & Midstream): Deployed in refineries, pipeline compressor stations, and gas processing plants. It conditions signals from pump and compressor vibration sensors, ensuring reliable data for process control and safety systems.
• Manufacturing (Automotive & Aerospace): Used in production lines for robotic arms, conveyor systems, and machine tools. The configurable range adapts to low-vibration precision equipment (e.g., CNC mills) and high-vibration stamping presses.
• Chemical & Pharmaceutical: Installed in control rooms for reactor 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. It processes signals from heavy-duty vibration transducers, transmitting data to SCADA systems to monitor equipment health in remote mining sites.
• Water & Wastewater Treatment: Used in pump stations and aeration systems. The transmitter converts signals from submersible pump vibration sensors into 4-20 mA outputs, enabling remote monitoring of equipment in wet environments.
• Marine & Offshore: Installed in ship engine control rooms and offshore platform control cabinets. The wide voltage range and EMI immunity ensure reliable performance in marine electrical systems prone to voltage fluctuations.
• Food & Beverage: Deployed in processing plants for mixers, blenders, and packaging machinery. The compact DIN rail design fits in small control cabinets, while the IP40 rating protects against dust and incidental moisture.
