Product Short Description
Technical Specifications:
- Input Types:
- Shaft vibration: Supports eddy current proximity probes (e.g., 3300 XL series) with a range of 0–2500 μm (0–100 mils) peak-to-peak.
- Bearing temperature: Accepts RTDs (PT100/PT1000) or thermocouples (Type J/K) for temperature monitoring up to 150°C (302°F).
- Oil pressure: Compatible with 4–20 mA pressure transducers for measuring lubrication oil pressure (0–100 bar/0–1450 psi range).
- Channel Configuration:
- 4 channels (2 for vibration, 1 for temperature, 1 for pressure).
- Frequency Response:
- Vibration: DC to 1 kHz (configurable low-pass filtering).
- Temperature/Pressure: DC to 10 Hz.

Functional Features:
- Multi-Parameter Monitoring:
- Simultaneously tracks vibration, temperature, and pressure for comprehensive bearing health assessment.
- Advanced Alarm Logic:
- Programmable thresholds for vibration, temperature, and pressure alarms with time-delayed activation to avoid false triggers.
- Alarm latching maintains alert status until manual reset.
- Dynamic Filtering:
- Configurable low-pass filters isolate specific fault frequencies (e.g., bearing wear, oil whirl).
- Self-Diagnostics:
- Continuously monitors module health and
sensor integrity, alerting users to faults or signal degradation.
- Hot-Swappable Design:
- Enables module replacement without system shutdown, minimizing downtime.
Application Scenarios:
- Power Generation:
- Monitors turbine and generator bearings in thermal and hydroelectric plants to prevent oil-film breakdown and rotor instability.
- Oil & Gas:
- Protects centrifugal compressors, pumps, and gas turbines in upstream/downstream operations by detecting bearing degradation early.
- Petrochemical Industry:
- Ensures reliability of rotating equipment in ethylene crackers, reactors, and distillation columns by tracking bearing conditions.
- Metallurgical Sector:
- Tracks vibration and temperature in blast furnace blowers, rolling mill gearboxes, and air separation units.
- Marine Propulsion:
- Monitors main engine bearings in ships and offshore platforms to avoid lubrication-related failures.
Certifications & Standards:
- Complies with API 670, ISO 10816, and ASTM E1085 for vibration monitoring.
- Meets EMC standards (EN 61326-1) for industrial environments.
- RoHS-compliant (Restriction of Hazardous Substances).
Compatibility:
- Exclusively designed for the Bently Nevada 3500 series machinery protection system.
- Seamless integration with Modbus and Ethernet communication modules (e.g., 3500/92) for DCS/PLC connectivity.
- Certified for hazardous area use (ATEX Zone 2, IECEx, CSA Class I Div 2).
