Bently Nevada 330910-00-07-05-02-05 / 330910-00-07-05-02-CN 3300 NSv Proximity Probes
Armored M10x1 probes with identical mechanical selections and 05 / CN approval configurations
Product Description
330910-00-07-05-02-05 and 330910-00-07-05-02-CN are armored, standard-mount Bently Nevada 3300 NSv proximity probes with an M10x1 case thread. Both use a 0 mm unthreaded section, a 70 mm overall case, a 0.5 m lead and the miniature coaxial ClickLoc connector with standard cable.
The narrow-side-view geometry supports measurements where side clearance is limited. In a complete 3300 XL NSv chain, the probe passes its signal through a matched NSv extension cable to a 330980 Proximitor Sensor. The assembled system can then provide static position and dynamic vibration information to the connected monitoring channel, using an approved 5 m or 7 m system length.
The final suffix is the controlled distinction: 330910-00-07-05-02-05 uses 05 for Multiple Approvals, while 330910-00-07-05-02-CN uses the CN country-specific approval selection. Mechanical fit and cable configuration remain alike, but destination labeling and certification requirements determine the correct suffix.

Monitoring & Control
When either probe is combined with the correct NSv extension cable and Proximitor Sensor, the complete transducer system supports radial vibration, axial or thrust position, tachometer and zero-speed measurements, and phase-reference or Keyphasor signals. The connected monitor determines the final channel function.
These performance values apply to the assembled transducer system under its specified target, gap, load and temperature conditions. They are not standalone electrical outputs from the probe alone.
Mechanical Design & Installation
M10x1 installation sequence
Both configurations use a 0 mm unthreaded length, 70 mm case length, 0.5 m total probe length and M10x1 case thread. Complete the installation in this order:
- Confirm the M10x1 mounting hole and verify that the selected 0 mm unthreaded length is at least 20 mm shorter than the 70 mm case.
- Thread the probe into the mounting hole while keeping thread engagement at or below 15 mm.
- Tighten the probe case to the recommended 11.3 N·m (100 in·lb); do not exceed 33.9 N·m (300 in·lb).
- Route the armored lead without tensile loading or sharp bends, maintaining a minimum 25.4 mm (1.0 in) bend radius.
- Mate the ClickLoc connector to the matching NSv extension cable and protect the connection against liquid ingress.
- Connect the matched extension cable to a 330980 Proximitor Sensor so the complete electrical length is 5 m or 7 m.
- Position the probe at the conductive target within the system's usable linear region, then confirm a stable reading at the connected monitoring channel.
Technical Questions
How should the approval suffix be selected between 330910-00-07-05-02-05 / 330910-00-07-05-02-CN?
Use the suffix required by the installation jurisdiction and certification package. The -05 configuration carries Multiple Approvals. The -CN configuration is the China country-specific option for applicable NEPSI/CCC and ATEX/IECEx marking requirements. The two suffixes identify different approval configurations and should not be treated as interchangeable.
Can 330910-00-07-05-02-05 / 330910-00-07-05-02-CN replace one another mechanically?
Their mechanical and cable selections are the same: 0 mm unthreaded length, 70 mm case length, 0.5 m total probe length, M10x1 case thread, armor and the standard-cable ClickLoc connector. The approval marking is the controlled difference, so replacement still requires confirmation against the site's certification and labeling requirements.
What additional components are needed to use 330910-00-07-05-02-05 / 330910-00-07-05-02-CN for a measurement channel?
Either probe must operate as part of a complete 3300 XL NSv transducer chain. Select the matching NSv extension cable and 330980 Proximitor Sensor so the assembled system has an approved 5 m or 7 m electrical length, then connect that system to the intended monitor or transmitter input.
Which mounting limits matter most when installing 330910-00-07-05-02-05 / 330910-00-07-05-02-CN?
For the M10x1 case, keep thread engagement at or below 15 mm. Unthreaded length must be at least 20 mm shorter than case length, which the 0 mm and 70 mm selections satisfy. Maintain a minimum 25.4 mm cable bend radius and avoid loading the armored cable at the probe body.
Does connector option 02 on 330910-00-07-05-02-05 / 330910-00-07-05-02-CN include a connector protector?
No. Option 02 specifies the miniature coaxial ClickLoc connector with standard cable and does not include the connector protector supplied with option 01. Protect probe-to-extension and extension-to-Proximitor connections against liquid ingress with the compatible connector protector or silicone self-fusing tape suitable for the installation environment.
Why Maintenance Teams Work with Moore
Procurement service
Confidence from enquiry to delivery
Maintenance purchasing often begins with a precise model and a limited time window. Moore Automation reviews the requested brand and complete model before quotation, then searches across current, discontinued and hard-to-find PLC, DCS, TSI, HMI, drive, sensor and control-system inventories.
The service is structured around clear identification, responsive communication and practical commercial terms rather than a generic company introduction.
