Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330104-09-20-50-02-00 | 3300 XL Proximity Transducer System
In any facility running high-speed rotating equipment — gas turbines, centrifugal compressors, steam turbines, or large pumps — shaft radial vibration is the single most critical parameter to monitor continuously. When a proximity transducer fails or is missing from the measurement chain, the machinery protection system goes blind. Operators lose the ability to detect rotor imbalance, oil whirl, misalignment, and bearing degradation before they escalate into catastrophic mechanical failure. The Bently Nevada 330104-09-20-50-02-00 Proximity Transducer System is the precision sensing element that keeps your machinery protection system fully operational — 24 hours a day, 365 days a year.
Where This Product Is Used
The 330104-09-20-50-02-00 is deployed across the most demanding rotating machinery applications in global industry:
- Oil & Gas Upstream: Wellhead gas compressors, gas lift compressors, and multiphase pumps on offshore platforms and onshore production facilities where continuous uptime is non-negotiable.
- LNG & Midstream: Main refrigerant compressor trains (MRC/PRC) in LNG liquefaction plants, where a single unplanned shutdown costs millions of dollars per day.
- Power Generation: Steam turbine-generator sets and gas turbine-compressor trains in combined-cycle power plants, monitored per API 670 and OEM specifications.
- Petrochemical & Refining: Cracked gas compressors, propylene refrigeration compressors, and reactor recycle compressors in ethylene and refinery units.
- Industrial Manufacturing: High-speed blowers, ID/FD fans, and large motor-driven equipment in steel mills, cement plants, and pulp & paper facilities.
- Marine & Offshore: Propulsion turbines and auxiliary rotating machinery on FPSOs and LNG carriers requiring continuous vibration surveillance.

Why Engineers Specify This Model
- Longer integral cable for deep installations: The 20 ft (6.10 m) integral cable configuration is specifically chosen for machinery where the bearing pedestal is far from the junction box or where cable routing requires additional reach — common in large steam turbines and multi-casing compressor trains.
- 9 mm probe tip for wider gap range: The 9 mm tip diameter provides a larger sensing field, making it more tolerant of shaft surface finish variations and target material inconsistencies encountered in field retrofits and older machinery.
- Non-contact eddy-current technology: Zero mechanical wear, infinite service life under continuous operation, and immunity to process fluid contamination — critical for probes installed inside bearing housings flooded with lube oil.
- API 670 compliance: Meets the requirements of API Standard 670 (Machinery Protection Systems), the mandatory specification for rotating equipment in oil & gas and petrochemical plants worldwide.
- Drop-in replacement: Fully backward-compatible with existing 3300 XL Proximitor® Sensor installations. No recalibration of the monitor rack is required upon replacement.
- High-temperature probe rating: Rated to +177°C at the probe tip, enabling installation in hot bearing pedestals adjacent to steam turbine casings and hot gas expanders.

Application-Specific FAQ
Q: What is the difference between the 330104-09-20-50-02-00 and the 330104-03-07-50-02-00?
A: The primary differences are probe tip diameter and integral cable length. The 330104-09-20-50-02-00 features a 9 mm probe tip and 20 ft (6.10 m) integral cable, while the 330104-03-07-50-02-00 has a 5 mm tip and 25 ft (7.62 m) cable. Tip diameter affects the sensing field size and gap range; cable length determines installation reach. Always verify your OEM specification sheet before substituting one configuration for another.
Q: Can the 330104-09-20-50-02-00 be used for axial position measurement as well as radial vibration?
A: Yes. Bently Nevada 3300 XL proximity transducers are used for both radial vibration (shaft displacement) and axial position (thrust position) measurement, depending on the mounting orientation and the monitor channel configuration. Confirm the monitor channel type (radial vs. thrust) with your system integrator.
Q: Is this probe suitable for use in ATEX Zone 1 hazardous areas?
A: ATEX certification is configuration-dependent. Please confirm the specific ATEX approval code required for your installation and contact us — we will verify the certification status of the unit supplied.
Q: Do you supply new or reconditioned units?
A: We supply both new-in-box and professionally reconditioned units. Please specify your requirement at the time of inquiry. New units carry a 12-month warranty; reconditioned units carry a 6-month warranty.
