Description
Bently 330850-90-05
Technical Specifications
- Product Series: 3300 XL 25mm System
- System Length: 9.0 meters (29.5 feet)
- Mounting Option: Panel Mount
- Agency Approval: 05 (Multiple Agency Approvals)
Functional Features
- Heavy-Duty Measurement: Supports the larger 25mm probes used for extreme axial displacement and low-frequency vibration monitoring.
- Hazardous Area Rated: Certified for safe installation in explosive or flammable industrial environments.
- Superior Signal Processing: Maintains high accuracy and linearity over long cable runs.
Application Scenarios
Critical for monitoring large steam turbines, synchronous motors, and heavy compressors where massive axial thrust movements must be accurately measured.
Performance Parameters
- Sensitivity: 7.87 V/mm (200 mV/mil) ±5%
- Linear Range: Extended range for 25mm system
- Power Supply: -17.5 to -26 Vdc
- Operating Temp: -35°C to +85°C
Material Composition
Ruggedized aluminum enclosure with integrated panel mounting flanges.
Structural Characteristics
Traditional panel-mount form factor with four mounting holes and standard terminal blocks.
Working Principle
Processes the high-frequency RF signal from the 25mm probe, converting impedance changes into a linearized DC voltage representing the gap.
Installation Requirements
Mount securely to a flat panel. Ensure the probe and extension cable combination totals exactly 9.0 meters.
Usage Precautions
Verify that the “-05” agency approval matches the specific hazardous area classification of the installation site.
