Product Overview

The Bently Nevada 330980-51-05 belongs to the 3300 XL NSv Proximitor Sensor family. This model shares many features with the 3300 XL 8 mm Proximitor Sensor. A thin design distinguishes the NSv version from older models. You can mount this sensor in high-density DIN-rail installations. Traditional panel mount configurations also work perfectly with this unit. Total system length reaches 5.0 meters (16.4 feet) as specified by option 51. The 330980-51-05 includes a DIN mount option for simplified installation. Agency approval option 05 provides multiple certifications for hazardous areas. Improved RFI/EMI immunity allows this sensor to achieve European CE mark approvals without special mounting considerations. This RFI immunity also prevents nearby high frequency radio signals from adversely affecting the transducer system.

Thin Design & Mounting Flexibility

The 330980-51-05 features a thin profile for space-constrained cabinets. High-density DIN-rail installations benefit from this slim design considerably. Alternatively, traditional panel mount configurations remain available for legacy systems. The DIN mount option (suffix 51) simplifies installation without additional hardware. Panel mounting uses the same footprint as other 3300 XL sensors when needed. For this reason, retrofits and upgrades proceed without cabinet rework. The Bently Nevada 330980-51-05 adapts to your preferred mounting method easily. SpringLoc terminal strips on the Proximitor Sensor require no special installation tools and facilitate faster, highly robust field wiring connections.

RFI/EMI Immunity

Improved RFI/EMI immunity protects the 330980-51-05 from electrical noise. Nearby high frequency radio signals do not affect transducer operation at all. European CE mark approvals are achieved without special mounting considerations. Special shielded conduit becomes completely unnecessary for this sensor. Metallic housings are also not required for CE compliance. Therefore, installation costs remain significantly lower than with older sensors. The Bently Nevada 330980-51-05 performs reliably even in electrically noisy environments. Radio frequency interference will not corrupt your measurements or affect system accuracy.

Agency Approvals (Option 05)

The 05 approval option provides multiple certifications for the 330980-51-05. These approvals typically include CSA, ATEX, and IECEx certifications for hazardous areas. CSA certification covers North American hazardous locations completely. ATEX approval permits European Union installation without additional testing. IECEx certification satisfies international requirements for explosive atmospheres worldwide. For global machine builders and export projects, these approvals prove absolutely essential. One sensor model serves many geographic markets simultaneously. Procurement and inventory management simplify as a result. The Bently Nevada 330980-51-05 meets rigorous safety standards for global use.

System Accuracy Conditions

The following specifications apply under specific conditions for the 330980-51-05. Temperature must stay between 0°C and +45°C (+32°F to +113°F) during calibration. Maximum altitude cannot exceed 2000 meters for rated accuracy. A -24 Vdc power supply is required for proper operation. A 10 kΩ load must be present at the output. The target must be Bently Nevada supplied AISI 4140 steel material. Target diameter must measure 31 mm (1.2 in) or larger for consistency. Probe gap must be set to 1.0 mm (40 mils) during calibration. System accuracy does not apply with other target materials at all. Interchangeability specifications also require the AISI 4140 steel target exclusively. For this reason, always use the specified target for rated accuracy with the 330980-51-05.

Probe Compatibility

The 330980-51-05 accepts specific probe types for proper operation. A 3300 RAM Proximity Probe connects directly to this sensor. A 3300 NSv Proximity Probe also works with this Proximitor. An extension cable joins the probe to the Proximitor for remote mounting. Always use genuine Bently Nevada components for best performance results. Mixed manufacturer components may reduce accuracy significantly. The Bently Nevada 330980-51-05 expects a complete Bently Nevada transducer system for rated specifications.

Installation Guidelines

Follow these steps for proper installation of the 330980-51-05.

1. Mount the sensor on DIN rail using the integrated clip for the 51 option.

2. Connect the 3300 RAM or NSv probe using the appropriate extension cable.

3. Wire the power supply observing correct polarity for -24 Vdc nominal.

4. Verify supply voltage stays within -17.5 Vdc to -26 Vdc without barriers.

5. Set probe gap to 1.0 mm (40 mils) for standard AISI 4140 steel targets.

6. Secure field wiring using SpringLoc terminal strips. No special tools needed.

7. Power up the system and check output voltage at the 10 kΩ load.

8. Verify proper operation by moving the target through the linear range.

Note: The 330980-51-05 requires a Bently Nevada AISI 4140 steel target for specified accuracy. Operation at voltages more positive than -23.5 Vdc may reduce linear range. Protect connectors from submersion to maintain humidity rating.

Common FAQs

1. What is the difference between the 330980-51-05 and the standard 3300 XL 8 mm Proximitor?

The 330980-51-05 uses a thinner design specifically for high-density mounting. It accepts 3300 RAM or NSv probes rather than 8 mm probes. Many other features remain similar, including RFI immunity and SpringLoc terminals. For NSv probe systems, this model is the correct choice without question.

2. What total length does the 51 option provide on the 330980-51-05?

The 51 suffix indicates 5.0 meters (16.4 feet) system length. This length includes the probe, extension cable, and Proximitor sensor completely. For medium-distance installations between probe and monitoring equipment, this length works well. Shorter or longer options are available with other suffix codes.

3. What approvals does the 05 option provide on the 330980-51-05?

The 05 option includes multiple approvals such as CSA, ATEX, and IECEx. CSA covers North American hazardous locations thoroughly. ATEX permits European Union installation without additional testing. IECEx satisfies international explosive atmosphere requirements globally. For worldwide applications, the 330980-51-05 with 05 approval meets multiple regulatory standards.

4. What is the operating temperature range for the 330980-51-05?

Operating temperature spans -52°C to +100°C (-62°F to +212°F). Storage temperature reaches -52°C to +105°C (-62°F to +221°F). Relative humidity tolerance reaches 100% condensing without damage. Connectors must remain protected from submersion for full humidity rating. Tested to IEC 68-2-3 damp heat standards. For this reason, the 330980-51-05 suits harsh industrial environments reliably.

5. Does the 330980-51-05 require a specific target material for accurate measurement?

Yes, Bently Nevada specifies an AISI 4140 steel target for rated accuracy. Target diameter must measure 31 mm or larger for proper calibration. System accuracy and interchangeability specifications only apply with this target material. For other target materials, recalibration becomes absolutely necessary. The 330980-51-05 achieves maximum accuracy only with the specified target.
