Description
Product Overview
Part Number: 330106-05-30-05-02-00 Manufacturer: Bently Nevada (Baker Hughes) Product Series: 3300 XL 11 mm Proximity Probe Type: Non-contact eddy current proximity probe, armored integral cable, M14×1.5 metric thread, USA manufactured. This 11mm eddy current probe is built for heavy rotating machinery with larger shaft movement. It measures radial shaft vibration, thrust displacement, shaft position and keyphasor signals for steam turbines, large centrifugal compressors, generators and heavy process pumps. It works together with matched 3300XL proximitor and Bently 3500 monitoring rack to provide real-time displacement data for machinery protection and predictive maintenance, conforming to API 670.

Engineer Notes
- This 11mm probe must pair with dedicated 3300XL 11mm proximitor. Total system cable length must follow datasheet specification to preserve scale factor accuracy.
- Recommended installation gap for 11mm 3300XL probe: approximately 2.5 mm. Verify gap voltage after installation.
- Target surface must be ferrous conductive steel. Non-ferrous metals alter scale factor and reduce measurement precision.
- Protect PPS probe tip from impact, scratches or cracking during mounting; physical damage causes signal drift.
- Armored cable design provides extra mechanical protection for harsh industrial environments.
- Never splice, cut or modify factory integral cable; unauthorized modification voids factory calibration and warranty.
- Apply proper torque on M14×1.5 threads; over-tightening can crack probe housing.
Pre-Shipment Test Protocol
- Continuity & insulation resistance test for probe plus armored integral cable
- Scale factor and linearity calibration test with standard steel target and precision gap gauge
- Noise floor and output signal stability inspection
- Full visual inspection: armor jacket, connector, probe tip and thread condition
- Part number, label and marking verification
- Calibration document review
- Anti-static & shock-resistant packaging check
Buyer FAQ
Q: Is 330106-05-30-05-02-00 new original? A: We supply brand new original Bently Nevada units, 12-month warranty, factory calibration certificate available on request.
Q: What proximitor should I use with this probe? A: It requires Bently Nevada 3300XL proximitor designed specifically for 11mm probe series.
Q: What applications suit this 11mm probe? A: Used for turbomachinery requiring larger linear measurement range, such as large compressors and heavy-duty steam turbines.
Q: What is the difference between 8mm and 11mm 3300XL probes? A: 11mm probe has wider linear range and lower scale factor, M14 thread vs M10 on 8mm probes; they are not interchangeable.
