Description
Bently 330878-90-00
Technical Specifications
- Product Series: 3300 XL 50mm System
- System Length: 9.0 meters (29.5 feet)
- Mounting Option: Panel Mount
- Agency Approval: Standard (00)
Functional Features
- Maximum Linear Range: Supports the largest 50mm probes for extreme axial displacement measurement on the largest rotating machinery.
- High Immunity: Advanced RFI/EMI filtering ensures reliable operation in heavy industrial environments.
- Signal Fidelity: Maintains precise linearity and sensitivity over the extended 9.0-meter cable length.
Application Scenarios
Critical for monitoring massive synchronous motors, large steam turbines, and heavy industrial compressors where extreme axial thrust movements must be accurately measured.
Performance Parameters
- Sensitivity: 7.87 V/mm (200 mV/mil) ±5%
- Linear Range: Extended range for 50mm system
- Power Supply: -17.5 to -26 Vdc
- Operating Temp: -35°C to +85°C
Material Composition
Durable aluminum enclosure with integrated panel mounting flanges.
Structural Characteristics
Rectangular panel-mount form factor with four mounting holes and standard screw-type terminal blocks.
Working Principle
Processes the RF signal from the 50mm probe/cable assembly, compensating for cable capacitance to deliver an accurate gap voltage.
Installation Requirements
Mount securely to a flat panel. Ensure the probe and extension cable combination totals exactly 9.0 meters.
Usage Precautions
Longer system lengths are more susceptible to noise. Ensure all cable connections are clean, tight, and properly shielded.
