Bently Nevada 330103‑00‑05‑10‑11‑00
3300‑XL 8 mm NSv Eddy‑Current Proximity Probe Assembly (Sleeve‑Mount Smooth‑Body, Standard‑Temperature, Non‑Hazardous‑Area)
Product Overview
The 330103‑00‑05‑10‑11‑00 belongs to Bently Nevada 3300‑XL 8 mm NSv non‑contact eddy‑current transducer series. This smooth‑body sleeve‑mount probe features no external mounting thread; it is secured inside a separate sleeve fixture, which is widely adopted for OEM turbomachinery, gearboxes and special‑structure bearing housings where threaded probe installation is not feasible. It performs radial shaft vibration and axial thrust‑position measurement for critical rotating equipment. It can also serve as Keyphasor phase‑reference sensor for speed and phase‑angle measurement when targeting shaft notch or keyway. This transducer meets API‑670 machinery‑protection requirements. Suffix ‑00 means no ATEX / IECEx / CSA intrinsic‑safety certifications, for non‑explosive general‑purpose industrial deployment.
Critical Compatibility Warning
- This is 8 mm NSv ClickLoc interface sleeve‑mount smooth‑body probe. Only compatible with 3300‑XL 8 mm NSv ClickLoc extension cables (330930 series). Not compatible with legacy Microdot probes/cables, ETR high‑temperature transducer sets or 11 mm NSv components.
- Total calibrated transducer loop length = probe integral pigtail length + matched 8 mm NSv extension‑cable length. Total physical loop length must strictly match the loop‑length parameter configured in paired NSv proximitor. Length mismatch results in sensitivity deviation and measurement error.
- Termination: Miniature ClickLoc quick‑lock coaxial connector. Do not cut, splice or modify factory‑molded integral pigtail assembly. This unit shall not be installed in explosive classified hazardous zones.

Critical note: Dedicated sleeve mounting fixture is mandatory for mechanical fixation. Side‑exit cable needs extra space during installation to avoid sharp bending. Target shaft material and surface coating will influence actual measuring performance. Avoid mechanical impact against probe tip. ClickLoc connector is finger‑tight only; wrench torque will permanently damage internal contact structure. Field splicing of factory‑integral pigtail cable is strictly prohibited. Not permitted for explosive classified hazardous locations.
Main Features
- Smooth‑body sleeve‑mount design: No external thread; relies on precision sleeve fixture for positioning and locking. Optimized for OEM‑supplied rotating machinery and compact bearing‑housing structures where threaded probes cannot be assembled.
- Short 50 mm housing with side‑exit cable: Side‑direction cable routing saves axial installation space, suitable for confined mounting cavities.
- 1.0 m factory‑calibrated non‑armored integral pigtail with Miniature ClickLoc connector: Works together with 330930 series 8 mm NSv ClickLoc extension cables to achieve required total transducer‑loop length.
- Standard‑temperature performance rating: Suitable for general‑purpose plant ambient‑temperature conditions; not applicable for continuous high radiant‑heat positions requiring ETR‑rated hardware.
- Compact heavy‑duty construction: Resists oil‑mist, humidity and machinery vibration, fulfils API‑670 protection requirements for critical rotating assets.
- Full interoperability within 3300‑XL 8 mm NSv ClickLoc transducer ecosystem.
Typical Application Scenarios
- Radial vibration and axial thrust‑position monitoring for OEM steam turbines, gas turbines, centrifugal compressors and gearboxes adopting sleeve‑mount probe cavities under non‑hazardous industrial zones
- Usable as Keyphasor phase‑reference sensor for rotational speed and vibration‑phase measurement when facing shaft notch / keyway
- Machinery‑house installations with pre‑machined smooth‑bore probe sleeves, common for original‑equipment integrated monitoring points
- System integration with Bently Nevada 3500 rack 8 mm NSv‑compatible proximitor input channels
- Spare‑part replacement for existing sleeve‑mount NSv proximity measurement loops

Installation and Configuration Guide
Warning: Installation must be performed by qualified instrument technicians. Always reference original Bently Nevada 3300‑XL NSv transducer‑system manual as primary technical document. This model carries no hazardous‑area certifications and shall not be deployed in explosive classified zones.
- Pre‑installation Total‑Length Calculation
- Calculate total NSv transducer loop length = probe integral pigtail (1.0 m) + selected 8 mm NSv extension‑cable length.
- Verify total physical length matches loop‑length parameter configured in paired NSv proximitor. Length mismatch will cause sensitivity drift and measurement inaccuracy. Reserve installation clearance for side‑exit cable to avoid sharp bend.
- Sleeve‑Mount Mechanical Installation
- Insert smooth‑body probe into pre‑installed precision sleeve fixture inside bearing housing. Adjust probe‑to‑shaft working gap to mid‑point of linear measuring range. Lock probe firmly via sleeve‑side clamping hardware, do not apply clamping force directly onto probe cable root.
- Confirm probe tip maintains safe clearance and will never contact rotating‑shaft surface over full operating‑speed and thermal‑expansion range. Protect side‑exit cable from squeezing and sharp bending during locking operation.
- Cable Routing & ClickLoc Connector Mating
- Route NSv transducer cable separately from high‑power AC, VFD and contactor wiring to mitigate EMI‑induced signal noise.
- Observe minimum static bending radius requirement; avoid sharp kinks especially at side‑exit cable root. Never pull cable assembly by ClickLoc connector housing.
- Align ClickLoc connector key‑slot, push inward and rotate clockwise until audible “click” for finger‑tight locking. Wrench tightening is strictly prohibited.
- Install strain‑relief clamps near connector joint. Deploy approved cable‑seal fitting when cable penetrates machine casing.
- System Commissioning
- Complete full NSv transducer‑loop assembly and power‑up proximitor / monitoring rack.
- Read static gap voltage to validate mechanical gap setting. Perform static‑gap calibration test with 8 mm NSv calibration fixture to verify system sensitivity.
- Clear Not‑OK fault status; configure vibration and thrust alarm / trip thresholds per project machinery specification.
- Maintenance & Troubleshooting
- During machinery turnaround, inspect sleeve clamping tightness, check side‑exit cable root for stress cracking, inspect ClickLoc connector for oil contamination and corrosion; inspect outer jacket for abrasion or aging deterioration.
- Gap‑voltage drift, abnormal vibration reading or persistent Not‑OK faults may originate from insufficient sleeve clamping force, improper installation gap, cable root bending damage, loose ClickLoc connection or incorrectly programmed loop‑length parameter.
- Replace complete factory probe assembly upon pigtail or probe‑tip damage; field‑splicing of integral probe pigtail cable is strictly prohibited.
Supplementary Remark
330103‑00‑05‑10‑11‑00 is a short‑body side‑exit 3300‑XL 8 mm NSv smooth‑body sleeve‑mount eddy‑current proximity probe with 50 mm housing and 1.0 m integral pigtail. Without hazardous‑area certifications, it is designed for radial vibration and thrust monitoring for OEM‑style rotating machinery adopting sleeve‑mount installation under non‑explosive industrial environments. It only interoperates with 8 mm NSv ClickLoc system components and cannot work with Microdot, ETR or 11 mm NSv hardware. Before commissioning, cross‑check sleeve fixture dimensional compatibility, total transducer‑loop length, side‑exit cable space requirement, ClickLoc interface and site area classification against project BOM and mechanical drawings.
