Description
Bently 3300/03-02-00
Technical Specifications
- Sensor Type: 3300 XL 8mm Proximity Probe
- System Length: 1.0 meter (3.3 feet)
- Thread Specification: Standard M10x1
Functional Features
- High Resolution: Provides precise measurement of shaft relative vibration and axial position.
- Interchangeability: Fully interchangeable within the 3300 XL 8mm system without individual calibration.
- Robust Connectors: Features ClickLoc connectors to prevent oil ingress and accidental disconnection.
Application Scenarios
Installed directly into bearing housings of steam turbines, compressors, and large motors for continuous radial vibration and displacement monitoring.
Performance Parameters
- Sensitivity: 7.87 V/mm (200 mV/mil)
- Linear Range: 2.0 mm (80 mils)
- Target Size: Minimum 15.2 mm diameter
- Temperature Range: -51°C to +177°C
Material Composition
High-temperature PEEK or ceramic sensing tip, stainless steel housing, and specialized shielded coaxial cable.
Structural Characteristics
Cylindrical probe body with precision-machined M10x1 threads, an extended smooth section for deep bearing access, and an integrated cable assembly.
Working Principle
Generates a high-frequency electromagnetic field at the probe tip. As the conductive shaft rotates, eddy currents are induced on the surface, changing the probe’s impedance proportionally to the gap distance.
Installation Requirements
Thread the probe into the bearing housing using the specified torque. Ensure the smooth section passes cleanly through the housing without binding.
Usage Precautions
Clean the mating threads and connector with an appropriate solvent before assembly. Apply thread sealant to prevent oil leakage into the housing.
