Bently 3500/32 125712-01

Description

• Technical Specifications
  • Power Parameters: Operates on 24V DC power supply (tolerance ±10%), with a maximum power consumption of 12 watts. Draws a nominal current of 500mA at 24V DC, compatible with the 3500 series rack’s power distribution system.
  • Input Configuration: Features 4 independent, isolated input channels. Each channel supports:
    • Accelerometers (IEPE): 2-wire/3-wire, 100mV/g to 500mV/g sensitivity
    • Velocity sensors: 2-wire/3-wire, 20mV/mm/s to 100mV/mm/s sensitivity
    • Eddy current proximity probes: -2V to -21V DC input range, 50kΩ input impedance
  • Measurement Capabilities:
    • Frequency range: 0.1 Hz to 10 kHz (vibration), 0 RPM to 30,000 RPM (speed-derived vibration)
    • Measurement types: Peak-to-peak displacement (0–500 μm), RMS velocity (0–200 mm/s), peak acceleration (0–50 g)
    • Accuracy: ±1% of full scale, 16-bit ADC resolution for high-precision data conversion
  • Output Performance: Provides 4 programmable 4–20mA analog outputs (1 per channel) and 8 relay outputs (2 per channel, configurable for alarm/trip). Relay contact rating: 30V DC/2A, 120V AC/1A.
  • Physical & Environmental Ratings: Dimensions of 241.3 mm (depth) × 24.4 mm (width) × 120.7 mm (height), net weight of 1.1 kg. Operating temperature range: -30°C to +65°C; storage temperature: -40°C to +85°C. Operates in 0–95% non-condensing humidity, IP20 protection rating (rack-mounted enclosure required).
  • Compliance Standards: Meets API 670 (machinery protection), ISO 10816 (vibration measurement), IEC 61000-6-4 (electromagnetic compatibility), and CSA/NRTL/C Class I, Division 2 hazardous location certification.
• Function Features
  • Multi-Sensor Compatibility: Supports three core vibration sensor types (accelerometers, velocity sensors, proximity probes) without additional signal converters, adapting to diverse machinery monitoring requirements.
  • Programmable Alarm & Trip Logic: Each channel allows independent configuration of alarm (warning) and trip (danger) thresholds for displacement, velocity, or acceleration. Supports latching/non-latching relay actions and time-delayed triggers to prevent false alarms.
  • High-Resolution Data Logging: Stores up to 10,000 historical data points per channel, including peak values, trend data, and alarm events. Data is retained in non-volatile memory during power outages for post-fault analysis.
  • Redundant Configuration Support: Compatible with 3500 series triple modular redundancy (TMR) systems. Two modules can be paired to provide hot-standby operation, ensuring continuous monitoring if one module fails.
  • Seamless System Integration: Communicates with 3500 rack interface modules via the backplane, supporting Modbus TCP/IP, Ethernet/IP, and Profinet protocols. Integrates with System 1 software for remote monitoring, data analysis, and predictive maintenance.
  • Self-Diagnostic Capabilities: Built-in diagnostics monitor module hardware, sensor connections, and signal integrity. Front-panel LED indicators (Power OK, Channel Active, Alarm, Trip) and software-based fault codes enable rapid troubleshooting.
• Application Scenarios
  • Power Generation Industry: Deployed in thermal, hydro, and nuclear power plants to monitor steam turbines, generators, coal mills, and feedwater pumps. Tracks vibration from rotor imbalance, bearing degradation, and shaft misalignment, triggering alarms to prevent catastrophic failures.
  • Oil & Gas Industry: Installed on offshore drilling rigs, pipeline compressors, centrifugal pumps, and gas turbines. Withstands high vibration, temperature fluctuations, and corrosive environments, ensuring reliable monitoring during extraction, transportation, and processing.
  • Petrochemical Industry: Used to monitor rotating equipment (gearboxes, agitators, reaction tower pumps) in refineries and chemical plants. Isolated input channels prevent ground loops in complex systems, while hazardous location certification supports use in flammable/explosive zones.
  • Metallurgical Industry: Applied to rolling mills, blast furnace fans, and air compressors in steel plants. Operates reliably in high-temperature, dusty conditions, monitoring vibration from mechanical wear and process-induced stress to avoid production interruptions.
  • Heavy Machinery Manufacturing: Integrated into test benches for large motors, industrial pumps, and construction equipment. Provides precise vibration data during product validation, enabling manufacturers to optimize design and ensure compliance with performance standards.
  • Marine & Naval Applications: Used in ship propulsion systems, marine turbines, and auxiliary machinery. The rugged design withstands salt fog, shock, and vibration, ensuring continuous machinery protection during long voyages.
  • Water & Wastewater Industry: Deployed in water treatment plants to monitor pumps, blowers, and mixers. Tracks vibration from cavitation, impeller wear, and bearing failure, supporting predictive maintenance and ensuring uninterrupted water supply.
