Bently Nevada 330907-05-30-10-12-05 NSv Probe

Bently Nevada 330907-05-30-10-12-05 3300 NSv Reverse Mount Probe

Product Introduction

The Bently Nevada 330907-05-30-10-12-05 belongs to the 3300 NSv series of reverse mount proximity probes. You can use this probe in process compressors and other harsh machinery applications. This model comes with M10x1 threads and a total length of 1.0 meter (39 inches). Additionally, it features a miniature coaxial ClickLoc connector with FluidLoc cable for superior environmental protection. The agency approval option 05 means this probe carries multiple global certifications.

Improved Design and Chemical Resistance

This NSv probe offers increased chemical resistance compared to the older 3300 RAM probe. Therefore, it performs reliably in many process compressor environments where chemical exposure is a concern. The side-view characteristics also surpass those of the 3000-series 190 probe when you set the gap at the same distance from the target.

The Bently Nevada 330907-05-30-10-12-05 uses gold-plated brass ClickLoc connectors throughout the transducer system. These connectors lock firmly into place and resist loosening from machine vibration. The patented TipLoc molding method creates a durable bond between the probe tip and the probe body. This bond ensures long-term mechanical integrity.

Electrical and Linear Range Specifications

Probe DC resistance measures 4.2 ± 0.5 ohms from the center conductor to the outer conductor.
For field wiring, you can use 0.2 to 1.5 mm² (16 to 24 AWG) cable.
We recommend using three-conductor shielded triad cable for optimal signal quality.
The maximum cable length between the 3300 XL NSv Proximitor Sensor and the monitor reaches 305 meters (1,000 feet).

Linear range extends to 1.5 mm (60 mils).
This range begins at approximately 0.25 mm (10 mils) from the target.
The full linear operating zone runs from 0.25 to 1.75 mm (10 to 70 mils), corresponding to approximately -1 to -13 Vdc.
Recommended gap setting is 1.0 mm (40 mils).

FluidLoc Cable Advantage

The connector option 12 provides FluidLoc cable on this model. This cable type offers enhanced resistance to oil, coolant, and other industrial fluids. Therefore, you can install the 330907-05-30-10-12-05 in wet environments with confidence. The FluidLoc construction prevents fluid migration along the cable into the connector or probe body.

Mechanical Specifications

Probe tip material uses Polyphenylene sulfide (PPS) for excellent chemical resistance.
Probe case material is AISI 304 stainless steel (SST).

For reverse mount probes like this one, the maximum rated torque is 22.6 N•m (200 in•lb).
However, the recommended torque is only 7.5 N•m (66 in•lb) to prevent damage.
Maximum length of thread engagement for M10x1 threads is 15 mm.

System weight varies by configuration. The probe itself weighs approximately 14 to 150 grams (0.5 to 5.3 oz).

Temperature and Pressure Limits

Operating temperature ranges from -52°C to +177°C (-62°F to +351°F).
Storage temperature matches the same range: -52°C to +177°C.

Important warning: Exposing the probe to temperatures below -34°C (-30°F) for a sustained period may cause premature failure of the pressure seal.

The Bently Nevada 330907-05-30-10-12-05 is designed to seal differential pressure between the probe tip and the case. The sealing material consists of a Viton O-ring for reliable pressure containment.

Agency Approval Option 05

This probe carries multiple agency approvals for global installation. You can use it in hazardous areas and regulated industries worldwide. The exact certification package includes ATEX, IECEx, CSA, and other regional approvals. Always check the product label or documentation for the complete list of certified markings.

Installation Guidelines

First, clean the mounting surface and threads thoroughly before installation.
Next, apply the recommended torque of 7.5 N•m (66 in•lb) only. Do not exceed 22.6 N•m.
Then, set the gap to 1.0 mm (40 mils) for optimal linear performance.
Use the ClickLoc connector to lock the FluidLoc cable securely. You will hear a click when it locks properly.
Finally, verify the DC resistance reading falls within 4.2 ± 0.5 ohms before commissioning.

Frequently Asked Questions (FAQ)

1. What makes FluidLoc cable different from standard cable on this probe?
FluidLoc cable provides enhanced resistance to oil, coolant, and industrial fluids. It prevents fluid migration along the cable into the connector, making it ideal for wet or lubricated environments.

2. Can I use the 330907-05-30-10-12-05 with existing 3300 XL NSv Proximitor Sensors?
Yes. This probe works with all 3300 XL NSv Proximitor Sensors that accept M10x1 threaded probes and ClickLoc connectors.

3. What multiple approvals does agency option 05 include?
Option 05 typically includes ATEX, IECEx, CSA, and other regional hazardous area approvals. Check the product label for the exact certification list for your unit.

4. Why is the recommended torque only 7.5 N•m when the maximum is 22.6 N•m?
The lower recommended torque prevents thread damage and case deformation while still providing a secure mechanical connection. Exceeding 7.5 N•m may risk stripping the threads.

5. How does the TipLoc molding method improve reliability?
TipLoc creates a robust, permanent bond between the probe tip and the probe body. This prevents separation or movement under vibration and thermal cycling, extending the probe's service life.
