3300 XL 8 mm sensing tip – Helps achieve a typical 2.0 mm (80 mil) linear range with low thermal drift when paired with the matching Proximitor.
Proven eddy-current technology – Stable shaft vibration and position measurements on conductive targets (AISI 4140 standard), even in oily environments.
System-matched performance – Nominal 7.87 mV/µm (200 mV/mil) sensitivity with the 3300 XL Proximitor 330180 for consistent readings across assets.
Rugged construction – IP68 probe tip, oil-resistant cable, and threaded mounting for secure installation near high-speed rotating shafts.
Flexible options – Thread form and cable length are determined by the option codes; armored or non-armored variants are commonly available.
Compatibility – Typically used with Bently Nevada 330180 Proximitor and 3500/3701/1900 series monitors for API 670 style protection systems.
| Brand / Model | Bently Nevada 330103-05-10-10-02-05 (3300 XL 8 mm Proximity Probe) |
| HS Code | 9031.80.00 (Measuring/Checking Instruments – Other) |
| Power Requirements | Passive probe; powered via matching 3300 XL Proximitor (e.g., 330180) |
| Measurement Principle | Eddy-current displacement measurement on conductive targets (AISI 4140 reference) |
| Linear Range | 2.0 mm (80 mil) typical with 8 mm system |
| Sensitivity | 7.87 mV/µm (200 mV/mil) nominal with 330180 Proximitor |
| Tip / Mounting | 8 mm tip; threaded mount via jam nut (M10x1 or 3/8-24 UNF depending on option code) |
| Cable | Integral cable; length and armor per option code (the “10-10-02-05” positions typically define these) |
| Operating Temperature | Probe: -35 to +180 °C; cable: up to +125 °C typical (depends on armor/material) |
| Environmental Rating | IP68 at probe tip; oil and splash resistant |
| Signal I/O | Analog voltage output via Proximitor to monitor (displacement/vibration) |
| Communication Interfaces | None (sensor-level) |

| Installation Method | Threaded mount with jam nut or bracket; gap set with voltmeter to Proximitor bias |
You might notice that these probes show up in most API 670 environments. Typical uses include:
Steam and gas turbines – Shaft vibration/position monitoring for trip and trending.
Compressors and expanders – Radial vibration and axial position measurements.
Pumps and motors – Bearing condition and shaft movement diagnostics in process lines.
Gearboxes and generators – Detecting rubs, misalignment, and early imbalance issues.
330180 Proximitor (3300 XL) – Required driver for the 8 mm system; provides power and scaling.
330130 Extension Cable – Extends probe cable length while maintaining system matching.
Mounting hardware (e.g., brackets and jam nuts) – For rigid, repeatable probe positioning.
3500/3701/1900-series monitors – Typically used for protection and condition monitoring.
Reliability under harsh conditions – Typically resists oil splash, temperature swings, and electrical noise found in real plants.
System compatibility – Works with standard Bently Nevada proximitor/monitor ecosystems many sites already deploy.
Lifecycle savings – Stable scaling and fewer nuisance trips reduce unplanned downtime and maintenance callouts.
Expert support – We help verify option codes, cable lengths, and threads so the new probe lands as a drop-in replacement.
Mounting and cabinet standards – Install the Proximitor in a ventilated control cabinet; maintain separation from high-voltage lines.
Probe positioning – Use a rigid bracket, maintain perpendicularity to the shaft, and set the gap using the Proximitor bias voltage (typically around -10 Vdc mid-range).
Wiring and grounding – Route sensor cables away from VFD power lines, observe minimum bend radius, and ground as per Bently Nevada guidelines.
Routine checks – Verify bias voltage during turnarounds, clean the probe tip if fouled, and re-check tightness of jam nuts.
Calibration practice – For best results, keep probe, extension cable, and Proximitor as a matched set; avoid mixing unless you re-calibrate.
Firmware/monitor updates – Keep rack or monitor firmware current to ensure stable trending and diagnostics.
Certifications: CE compliance; RoHS alignment is typical for current production. Manufactured under ISO 9001 quality systems.
Warranty: 365-day warranty coverage from delivery date.
One thing I appreciate is how predictable the 330103 behaves once gapped correctly—less chasing drift, more time focusing on actual machine faults. If you’d like, I can help decode the “-05-10-10-02-05” option set to confirm thread type, cable length, and armor so it matches your existing probes.
