8 mm tip for standard industrial clearances – Ideal for medium‑to‑large shaft diameters where robust mechanical standoff is needed.
High‑sensitivity output (system 200 mV/mil) – With 330180 Proximitor, you get the typical 200 mV/mil scale widely used in API 670 applications.
Stability across temperature and time – The 3300 XL design is known for low drift, which in many cases reduces re‑calibration frequency.
Full system compatibility – Works with 330130 extension cables and 330180 Proximitor Sensors; signals are accepted by 3500 and legacy 3300 monitoring systems.
Rugged, oil‑tolerant construction – Designed for harsh rotating equipment environments with proper shielding for electrical noise immunity.
Proven linear range – Typically supports an 80 mil (≈2.0 mm) linear range for displacement and vibration measurements on metallic targets.
| Brand / Model | Bently Nevada 330101-00-20-05-02-00 (3300 XL 8 mm Proximity Probe) |
|---|---|
| HS Code | 9031.80.00 (Measuring/Checking Instruments; final classification may vary by destination) |
| Power Requirements | Probe is passive; operates with 3300 XL Proximitor Sensor (P/N 330180), typically powered at −24 V DC nominal |
| Signal Input/Output Types | Eddy‑current displacement probe; system sensitivity typically 200 mV/mil (≈7.87 mV/μm) via Proximitor voltage output |
| Operating Temperature | Probe/cable typically −35 to +177 °C (configuration dependent) |
| Dimensions & Mounting | 8 mm probe tip; typical mounting thread 3/8‑24 UNF‑2A with locknut; standard linear range ≈2.0 mm (80 mil) |
| Communication Interfaces | None (analog voltage output via Proximitor to monitor) |
| Installation Method | Threaded insertion into bracket/boss; connect to 330130 extension cable and 330180 Proximitor Sensor; set gap typically at 1.0 mm (40 mil) |
From my experience, this probe is a safe choice for critical rotating assets where unplanned downtime is costly:
Steam and gas turbines – radial vibration and differential expansion (with proper mechanical arrangements)
Centrifugal and screw compressors – shaft vibration and axial position
API 610/ISO 13709 pumps – bearing housing vibration via proximity measurements
Gearboxes and motors – shaft orbit/phase reference with Keyphasor arrangements
You might notice that switching from mixed probe families to 3300 XL typically simplifies spares and scaling across units, which helps maintenance teams standardize trending rules.
Reliability – Stable calibration and low noise floor mean fewer nuisance alarms and cleaner trends.
Compatibility – Pairs cleanly with 330130 extension cables, 330180 Proximitor Sensors, and 3500/3300 monitors.
Lifecycle savings – Interchangeable components and broad installed base usually reduce training and spare parts complexity.
Technical support – Widely documented installation practices and API 670‑aligned methods streamline audits and acceptance testing.
A maintenance engineer told us after a turnaround, “Swapping to 3300 XL 8 mm helped us standardize all gap checks at 40 mils—commissioning went faster, and our baseline spectra were immediately stable.”
Installation & MaintenanceMounting – Install in a rigid, vibration‑free bracket/boss; avoid cantilevered mounts. Typical thread is 3/8‑24 UNF‑2A; use the supplied locknut.
Gap setting – Set cold gap typically at 1.0 mm (40 mil) to maintain linear range over thermal growth; verify DC bias voltage at the monitor.
Cable routing – Route probe/extension cables away from VFD power leads; maintain shielding integrity and avoid sharp bends or crush points.
Cabinet & ventilation – Mount Proximitor Sensors in a clean, dry marshalling cabinet with adequate ventilation; follow −24 V DC supply polarity.
Safety – Lock‑out/tag‑out rotating equipment; confirm mechanical clearances before setting final gap.
Routine checks – Periodically inspect probe tips for debris buildup, confirm tightness of locknuts, and review system linearity using a proximity probe calibrator when practical.
CE marked; RoHS compliant in most configurations; manufactured under ISO 9001 quality systems
