Bently Nevada 3300 XL Probe 330170-00-08-20-02-05
Overview: The Sensing Element of Machinery Protection Systems
The Bently Nevada 3300 XL Probe, part number 330170-00-08-20-02-05, is a sensing probe within the 3300 XL Proximity Transducer System family, used for radial vibration and axial position measurement on fluid-film bearing machines throughout rotating equipment protection systems. Like other members of the interchangeable 3300 XL probe range, this probe pairs with a compatible 3300 XL Proximitor sensor to form a complete non-contact displacement measurement system central to turbine, compressor, and pump condition monitoring.
As an authorized supplier of Bently Nevada machinery protection instrumentation, Seven Star LLC sources and supplies the 3300 XL probe to refineries, gas processing plants, and power generation facilities across Oman and the wider GCC. Because probe interchangeability and correct ordering configuration are critical to maintaining an existing 3300 XL system’s calibration, Seven Star LLC helps maintenance teams confirm the exact suffix code required for their installed base.
Measurement Principle
The 3300 XL proximity transducer system generates an output voltage directly proportional to the distance between the probe tip and an observed conductive surface – typically a rotating shaft – enabling both static (position) and dynamic (vibration) measurement from the same sensing element. This eddy-current-based displacement principle allows continuous, non-contact monitoring of shaft position and radial vibration without any physical wear on the measurement point itself, a critical requirement for machinery that must run continuously between major overhauls.
Bently Nevada’s 3300 XL family maintains a consistent incremental scale factor of 7.87 V/mm (200 mV/mil) ±5% across standard 1 or 5 meter systems, with a recommended radial vibration gap setting of -9 Vdc (approximately 1.27 mm / 50 mils) and deviation from the best-fit straight line held to ±0.025 mm (±1 mil), giving the probe the precision required for both routine condition monitoring and machinery protection trip logic.
Engineering Design of the 3300 XL Probe
The 3300 XL probe and extension cable incorporate two patented design improvements over earlier probe generations: a TipLoc molding method that provides a more robust bond between the probe tip and probe body, and a CableLoc cable design that delivers 330 N (75 lbf) pull strength to more securely attach the probe cable to the probe tip. The probe tip itself is molded from polyphenylene sulfide (PPS), while the probe case is constructed from AISI 303 or 304 stainless steel, rated for an operating and storage temperature range of -52°C to +177°C (-62°F to +350°F).
The 330170 series designation reflects a specific probe configuration within the broader 3300 XL family, and the -05 approval option code indicates CSA, ATEX, and IECEx hazardous-area certification, making it suitable for installation in classified areas common to refinery and gas processing rotating equipment. A miniature coaxial ClickLoc connector terminates the standard cable, ensuring reliable, repeatable connection to the mating Proximitor sensor cable.
Key Features
The Bently Nevada 3300 XL Probe delivers precise, reliable non-contact shaft measurement. Key characteristics include:
- 2 mm (80 mil) linear measuring range with ±0.025 mm deviation from best-fit straight line.
- TipLoc molded tip bond and CableLoc cable retention (330 N / 75 lbf pull strength).
- Miniature coaxial ClickLoc connector for reliable Proximitor sensor connection.
- PPS probe tip and AISI 303/304 stainless steel case construction.
- Operating temperature range of -52°C to +177°C.
- CSA, ATEX, and IECEx hazardous-area approvals (option -05).
- Full interchangeability with existing 3300 XL Proximitor sensor systems.
Industrial Applications
The 3300 XL probe is deployed across turbines, centrifugal compressors, pumps, and other fluid-film bearing machinery in refineries, gas processing plants, and power generation facilities, providing the radial vibration and axial position data that machinery protection and condition monitoring systems depend on. Its role in Keyphasor reference and speed measurement applications also supports balancing and diagnostic analysis on critical rotating equipment.
Seven Star LLC supports refinery instrumentation teams, gas processing operators, and power plant maintenance departments across Oman, Muscat, Sohar, and the broader GCC region with sourcing of Bently Nevada 3300 XL probes, helping plants maintain continuous, reliable machinery protection coverage.

Why Choose Seven Star LLC for Machinery Protection Probe Sourcing
Replacing a single 3300 XL probe on an existing machinery protection system is not a generic proximity-sensor purchase – the specific suffix code (approval options, cable length, connector type) must match both the installed Proximitor sensor and the system’s original calibration, since even a probe that looks physically identical can shift the incremental scale factor the trip logic depends on. Seven Star LLC’s engineers verify the exact 330170 series configuration against the customer’s existing installed base before the probe ships, rather than assuming a similar part number is interchangeable. We also help refinery and power plant instrumentation teams across Oman plan spare probe stock for critical turbine and compressor trains, and coordinate delivery around planned outages across Muscat, Sohar, and the broader GCC.
