Section 3: Product Introduction
The BENTLY 330901-00-70-10-02-CN is an 8 mm eddy current proximity probe from the specialized 3300 XL NSv series. It is specifically engineered for applications with limited installation space, such as small shafts, side-view configurations, and restricted areas in centrifugal compressors, pumps, and fans.
Unlike standard 8 mm probes, the NSv series features enhanced side-view performance and small-target measurement capabilities. This 7.0 m system length probe complies strictly with API 670 standards and offers full interchangeability within the 3300 XL NSv ecosystem, eliminating the need for individual system matching.

Section 5: Quality Control Process (Engineer’s Perspective)
- Incoming Verification: We check source traceability and verify serial numbers against anti-counterfeit databases. Visual inspection confirms no physical damage or connector corrosion.
- Live Functional Test: Power-on self-checks validate basic operation. We run continuous load tests exceeding 24 hours with temperature logging to ensure stability.
- Electrical Parameter Test: Insulation resistance is verified using a 500 V Megger, requiring >10 MΩ. Ground continuity is also strictly checked.
- Linearity Calibration: NSv probes are verified using a TK-3E eddy current probe calibrator to ensure linearity deviation (DSL) remains within ±0.06 mm.
- Final QC & Packaging: The unit is sealed in an anti-static bag. A QC Passed label with the inspection date is applied before shipping.

Section 6: Replacement Pitfall Guide
❗ NSv vs. Standard 8mm Confusion: The 330901 is an NSv (Non-Standard View) probe. Do not substitute it with a standard 330104 series probe, as the NSv has a shorter linear range (1.5 mm vs 2.0 mm) and different side-view characteristics.
❗ System Length Mismatch: The electrical length of the probe must exactly match the proximitors’ rating. A 7.0 m NSv probe requires a proximitors rated for exactly 7.0 m.
❗ Small Target Limitations: If measuring axial position on a shaft smaller than 13 mm (0.5 in), the sensitivity factor may vary. Reduce the probe-to-target gap to minimize scale factor changes.
❗ Cable Termination Issues: Always verify shield grounding at the third terminal block. Improper grounding here is the #1 cause of 60 Hz hum in vibration data.
❗ ESD Damage: Use an anti-static mat during installation. Dry environments significantly increase electrostatic discharge risks to sensitive electronics.
Keep these in mind and you’ll cut 90% of rework time.
Section 7: Compatibility Matrix & Benchmarks
- 330901-00-70-10-02-CN → 330901-00-40-10-02-05 : Needs Adaptation — different system length (7.0 m vs 4.0 m)
- 330901-00-70-10-02-CN → 330901-00-70-10-02-00 : Direct — same probe, standard agency approvals vs. CN
- 330901-00-70-10-02-CN → 330104-00-70-10-02-00 : Incompatible — Standard 8mm vs. NSv series
- Paired Proximitor: 330980-70-00-CN or 990-05-70-01-CN
- Output Linearity: DSL < ±0.06 mm over 60 mil range
