Description
Bently 330108-91-05
Technical Specifications
- Part Number: 330108-91-05
- Probe Type: Eddy Current Proximity Probe
- Thread Size: Standard industrial metric or imperial thread (based on configuration)
Key Features
- High-Frequency Response: Accurately captures high-speed shaft vibrations and transient events.
- Robust Construction: Built to withstand extreme mechanical shock and vibration.
- Long-Term Stability: Minimal drift over extended operational periods.
Application Scenarios
Used in critical rotating equipment across the oil and gas, power generation, and marine industries for real-time shaft dynamics monitoring.
Performance Parameters
- Measurement Range: Typically 2mm (80 mils) linear range for standard 8mm probes.
- Temperature Rating: -40°C to +177°C (-40°F to +350°F)
Material Composition
Precision-machined 316L stainless steel body with high-temperature PTFE dielectric insulation.
Structural Characteristics
Features a precision-threaded mounting section and a specialized cable exit designed for secure connection to armored extension cables.
Working Principle
The probe acts as an inductor in a high-frequency resonant circuit. The proximity of the conductive target (shaft) alters the inductance, which is subsequently demodulated by the Proximitor into a usable DC voltage.
Installation Requirements
Clean the mounting hole thoroughly before installation. Use a locknut and proper sealing compound to prevent oil leakage and ensure the probe remains securely positioned.
Usage Precautions
Do not use abrasive materials to clean the probe tip. Ensure the target surface is free of deep scratches or non-conductive coatings that could distort the magnetic field.
