3500/44-01-00 multi-function integrated monitoring module

The BENTLY 3500/44-01-00 is a multi-function integrated monitoring module in Bently Nevada’s 3500 Series Rotating Machinery Protection & Monitoring System. It integrates vibration, displacement, temperature, and other key parameter monitoring capabilities into a single module, designed to provide comprehensive health status tracking and safety protection for large rotating equipment (such as steam turbines, centrifugal compressors, and generators). With its flexible sensor compatibility and configurable alarm logic, it eliminates the need for multiple single-function modules, simplifying system architecture while ensuring high-precision and real-time monitoring. Below is its comprehensive detailed information:

I. Core Technical Parameters

Category	Specific Specifications
Basic Identification	- Model: 3500/44-01-00 (Multi-Parameter Integrated Monitor)- Applicable System: Bently 3500 Series (compatible with 3500/10 single-frame and 3500/20 multi-frame racks)- Channel Configuration: 4 vibration/displacement channels + 4 temperature channels (independent signal processing)
Vibration/Displacement Monitoring	- Measurable Parameters: Radial vibration, axial position, differential expansion, rotor eccentricity, absolute vibration (via seismic sensors)- Sensor Compatibility:- Eddy current probes (e.g., Bently 3300XL 5mm/8mm/11mm): for displacement/vibration (sensitivity: 3.94mV/µm or 7.87mV/µm)- Velocity sensors: for vibration (0.1~100 mm/s range)- Accelerometers: for high-frequency vibration (0.1~500 g range)- Accuracy: ±0.2% of full scale (at 25°C)- Frequency Response: 0.1 Hz ~ 10 kHz (configurable via software filters)
Temperature Monitoring	- Sensor Compatibility: Type E/J/K/T thermocouples (TC), 2-wire/3-wire Pt100 RTDs- Measurement Range: -200°C ~ +600°C (TC: -200°C~+1300°C optional)- Accuracy: ±0.1°C (for RTDs, -50°C~+150°C); ±0.3°C (for TC, with cold-junction compensation)- Update Rate: 1s/channel
Input/Output Interface	- Inputs: 4 vibration/displacement sensor inputs + 4 temperature sensor inputs (all isolated to avoid cross-interference)- Outputs:- 6 Form C (SPDT) relays (configurable for "Warning/Danger" alarms or equipment trip signals)- 4 4-20 mA analog outputs (proportional to measured values, 1 per key parameter)- 1 dedicated buffered output (for external data logging/analysis, impedance: 550Ω)- Communication: Integrates with 3500 rack backplane, supports data synchronization with other modules (e.g., 3500/50 speed module)
