Proven Application Environments
- Steam & Gas Turbines — radial shaft vibration and axial position monitoring per API 670
- Centrifugal Compressors — continuous rotor orbit and eccentricity measurement
- Boiler Feed Pumps — high-temperature bearing journal displacement
- Gearboxes & Expanders — gear mesh frequency and shaft runout detection
- Hydro Turbines — slow-speed shaft position and thrust monitoring
- Petrochemical Reactors — agitator shaft surveillance in hazardous areas
Engineering Advantages
- Non-contact measurement — zero mechanical wear, infinite service life on the sensing element
- Sub-micron resolution — detects shaft displacements as small as 0.25 µm under dynamic conditions
- Wide thermal stability — maintains calibration accuracy from cryogenic to high-temperature process environments
- Armored integral cable — resists oil, steam, and chemical ingress; rated IP67
- API 670 compliant — drop-in replacement for existing 3300 NSv installations without recalibration
- CN connector variant — optimized for Chinese domestic installations and local maintenance workflows
System Architecture & Signal Flow
The 330910-00-07-10-02-CN operates as part of the Bently Nevada 3300 NSv three-component measurement chain:
- Proximity Probe (330910-00-07-10-02-CN) — generates a high-frequency electromagnetic field; target eddy currents modulate the field proportional to gap distance.
- Extension Cable (3300 XL series) — transmits the modulated RF signal with minimal loss over the 2 m CN-terminated extension.
- Proximitor® Driver / Signal Conditioner — demodulates the RF signal and outputs a calibrated DC voltage (−10 VDC at nominal gap).
- 3300 Monitor Module — digitizes the conditioned signal, applies alarm setpoints, and transmits data to the plant DCS/historian via 4–20 mA or Modbus.
All three components must be purchased as a matched set calibrated to the same scale factor (7.87 V/mm) to maintain API 670 measurement chain accuracy.

Technical FAQ
Q: Can the 330910-00-07-10-02-CN replace a 330910-00-07-10-02-00 (standard connector)?
A: The CN suffix denotes the Chinese-standard 2-pin connector. The probe body and calibration are identical; only the connector differs. Verify your junction box accepts the CN connector before substituting.
Q: What is the maximum shaft speed this probe can monitor?
A: The 10,000 Hz frequency response supports shaft speeds up to 600,000 RPM for 1× vibration measurement, well beyond the range of any industrial rotating machine.
Q: Does this probe require field calibration after installation?
A: No. The 3300 NSv measurement chain is factory-calibrated as a matched set. Field calibration is only required if the probe, extension cable, or driver is replaced individually with a non-matched component.
Q: Is this probe suitable for use in ATEX Zone 1 hazardous areas?
A: Consult the Bently Nevada ATEX certificate for the specific zone classification. The 3300 NSv system has ATEX-certified configurations; confirm the complete installation meets the zone requirements of your facility.
Q: What is the minimum order quantity?
A: Single units are available. Contact us for volume discounts on orders of 5+ units.
