Product Overview
The Bently Nevada 330903-00-05-70-12-00 is an advanced eddy current proximity probe.
It belongs to the compact 3300 NSv Series transducer line.
Engineers design this probe for tight installation spaces and small shaft target diameters.
The probe tip features polyphenylene sulfide material for superior process chemical resistance.
The internal Viton O-ring creates a reliable differential pressure barrier between tip and case.
This unit features FluidLoc cable to block fluid leakage through the cable interior.

Model Selection Comparison & Technical Advice
| Feature / Option | 330903-00-05-70-12-00 | 330903-00-04-70-11-05 |
| Case Length | 50 mm overall case length (-05-) | 40 mm overall case length (-04-) |
| Cable Technology | FluidLoc cable preventing oil migration (-12-) | Standard coaxial ClickLoc cable (-11-) |
| Agency Approvals | Uncertified for non-hazardous locations (-00-) | ATEX, CSA, IECEx hazardous area approved (-05-) |

Engineering Advice: Choose the 330903-00-05-70-12-00 when installing probes inside oil-flooded compressor casings.
The FluidLoc cable stops oil migration along internal wire strands into external terminal boxes.
If your installation site requires hazardous area certifications, select model 330903-00-04-70-11-05 instead.
Installation & Torque Guidelines
- Mount the M8x1 threaded body with a maximum probe case torque of 7.3 N·m (65 in·lb).
- Apply recommended installation torque of 5.1 N·m (45 in·lb) for standard mounting.
- Tighten miniature coaxial ClickLoc connectors finger-tight, never exceeding 0.56 N·m (5 in·lb).
- Maintain a minimum cable bend radius of 25.4 mm (1.0 in) during wire routing.
- Set the initial mechanical gap to 1.0 mm (40 mils) or approximately -9.0 Vdc voltage output.
Commissioning & System Compatibility
The 330191 probe architecture matches Bently Nevada 3300 XL NSv Proximitor Sensors.
It maintains mechanical and electrical interchangeability with older legacy 3300 RAM proximity components.
Field technicians can run up to 305 meters of three-conductor shielded triad field wiring.

Global PLC Spare HUB's Insight
During field retrofits on centrifugal gas compressors, standard probe cables often leak oil into junction boxes.
The 330903-00-05-70-12-00 eliminates this failure mode through its specialized FluidLoc cable construction.
When target diameters are under 13 mm, scale factors shift slightly due to target curvature.
Our engineers recommend reducing initial gap settings slightly on small shafts to maintain optimal linear output.
Purchasing Guide & Frequently Asked Questions
Q: What is the main advantage of the FluidLoc cable option (-12-)?
A: It prevents process oil and liquids from traveling through the interior cable structure into external enclosures.
Q: Can I use this 7.0-meter probe without an additional extension cable?
A: Yes, this 7.0-meter probe connects directly to a matching 7.0-meter Proximitor Sensor system.
Q: What happens if the shaft target diameter is smaller than 13 mm?
A: Scale factor changes slightly, but setting a closer probe gap mitigates signal deviation effectively.
Q: How does the 3300 NSv probe compare to legacy 3300 RAM probes?
A: It offers identical form factors with improved chemical resistance and superior side-view gap characteristics.
Q: How do I choose between Option -00- and Option -05- agency approvals?
A: Choose Option -00- for safe general areas; select Option -05- for hazardous explosive atmospheres requiring ATEX or IECEx.
