Description
Bently 330901-00-90-10-02-05
Technical Specifications
- Sensor Type: 3300 XL 11mm Proximity Probe
- Thread Length: 90 mm
- Smooth Length: 100 mm
- System Length: 1.0 meter (3.3 feet)
Functional Features
- Extended Linear Range: Offers a wider linear measurement range (up to 4.0 mm / 160 mils) compared to standard 8mm probes.
- Large Target Compatibility: Ideal for measuring larger shafts (minimum diameter 25.4 mm) and applications requiring significant axial displacement measurement.
- System Interchangeability: Fully interchangeable within the 3300 XL 11mm system.
Application Scenarios
Extensively used for axial displacement (thrust position) monitoring on large steam turbines, centrifugal compressors, and heavy-duty industrial fans.
Performance Parameters
- Sensitivity: 7.87 V/mm (200 mV/mil) ±5%
- Linear Range: 4.0 mm (160 mils)
- Minimum Shaft Diameter: 25.4 mm (1.0 inch)
- Frequency Response: DC to 10 kHz
Material Composition
Precision-machined stainless steel housing, high-temperature PEEK sensing tip, and shielded coaxial cable with ClickLoc connectors.
Structural Characteristics
11mm diameter cylindrical body with mounting threads, an extended smooth section for deep bearing access, and an integrated 1.0-meter cable assembly.
Working Principle
Operates on the same eddy current principle as the 8mm probe but with a larger coil geometry, providing a wider linear measurement field.
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
Ensure the target shaft diameter meets the minimum requirement. Clean the mating threads and apply thread sealant to prevent oil leakage.
