Description
Bently 330780-90-00
Technical Specifications
- Product Series: 3300 XL 11mm System
- System Length: 9.0 meters (29.5 feet)
- Mounting Option: Panel Mount
- Agency Approval: Standard (00)
Functional Features
- Extended Reach: Supports system lengths up to 9.0 meters, allowing transducers to be located in safe, climate-controlled panels far from the machinery.
- High Immunity: Advanced RFI/EMI filtering ensures reliable operation even in the presence of variable frequency drives and radio transmitters.
- Signal Fidelity: Maintains precise linearity and sensitivity over the extended cable length.
Application Scenarios
Used in large turbine halls or outdoor compressor stations where the monitoring rack is situated at a considerable distance from the bearing pedestals.
Performance Parameters
- Sensitivity: 7.87 V/mm (200 mV/mil) ±5%
- Linear Range: 4.0 mm (160 mils)
- 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 9.0-meter probe/cable assembly, compensating for cable capacitance to deliver an accurate gap voltage.
Installation Requirements
Mount securely to a flat panel using the provided hardware. 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.
