Bently Nevad 3300 NSv Armored Probe 330909-00-13-05-01-05

Bently Nevada 330909-00-13-05-01-05 3300 NSv Proximity Probe

Product Introduction

The Bently Nevada 330909-00-13-05-01-05 is a ruggedized member of the 3300 NSv probe family, distinguished by its stainless steel armor. This armor provides superior mechanical protection against abrasion and impact, making it particularly suitable for harsh installation environments. Additionally, this model carries multiple agency approvals (option 05), simplifying compliance for global installations. The probe features a 0.0-inch unthreaded length and a 1.3-inch overall case length, with a 0.5-meter cable terminated by a ClickLoc connector with a protective cover.

Technical Specifications

The 330909-00-13-05-01-05 sensor employs a probe case manufactured from AISI 304 stainless steel and a tip constructed from Polyphenylene sulfide (PPS). Its unthreaded length option -00 indicates no unthreaded section, while the -13 overall case length provides a compact 1.3-inch housing. The total length option -05 specifies a 0.5-meter (20-inch) cable. Furthermore, the connector option -01 includes a miniature coaxial ClickLoc connector with a connector protector. The cable uses 75 Ω coaxial construction with FEP insulation, ensuring excellent signal fidelity. The agency approval option -05 confirms multiple certifications, including those for hazardous area installations.

Electrical Performance Parameters

For the 3300 NSv probe with a 0.5-meter length, the DC resistance from the center conductor to the outer conductor (RPROBE) is 4.0 ± 0.5 ohms. This low resistance ensures minimal signal loss during operation. The probe delivers reliable performance across its specified linear range, providing accurate vibration and position measurements for critical rotating machinery. The incremental scale factor and frequency response characteristics remain consistent with the 3300 NSv series standards.

Mechanical and Environmental Ratings

The 330909-00-13-05-01-05 probe operates and stores within a temperature range of -52°C to +177°C (-62°F to +351°F) . However, sustained exposure below -34°C (-30°F) may compromise the Viton O-ring pressure seal. For the probe case torque on 3/8-24 threads, the maximum rated value is 33.9 N•m (300 in•lb) , while the recommended torque is 11.3 N•m (100 in•lb) . For the first three threads, the maximum rated torque is 22.6 N•m (200 in•lb) with a recommended setting of 7.5 N•m (66 in•lb) . The maximum thread engagement length is 0.563 inches. The armored construction adds mechanical robustness without significantly increasing the probe's weight, which ranges from 14 to 150 grams.

Armor Features and Benefits

The stainless steel armor on this 3300 NSv probe offers exceptional protection against physical damage during installation and operation. Specifically, it shields the cable from abrasion, crush forces, and cutting hazards commonly encountered in process compressor environments. The armor also enhances the probe's durability in high-vibration applications where unprotected cables might suffer fatigue failure. Despite this added protection, the probe maintains excellent flexibility with a minimum bend radius of 25.4 mm (1.0 inch), allowing for practical routing in tight spaces.

Installation Guidance

When installing the 330909-00-13-05-01-05 probe, first verify that the target surface meets the minimum diameter requirement of 13 mm (0.5 inches). Next, carefully thread the 3/8-24 UNF probe into the mounting fixture, ensuring proper alignment to avoid cross-threading. Then, tighten the probe to the recommended torque of 11.3 N•m using a calibrated torque wrench. For the connector-to-connector interface, apply 7.5 N•m of torque to achieve a secure connection. Additionally, ensure the thread engagement does not exceed 0.563 inches. The armored cable should be routed with adequate support to prevent excessive bending or strain.

Frequently Asked Questions (FAQ)

1. What does the multiple approvals option (05) mean for the Bently Nevada 330909 probe?
The agency approval option -05 indicates that this 330909-00-13-05-01-05 probe carries certifications for use in hazardous areas, including ATEX, CSA, and IECEx approvals. This simplifies global compliance and allows installation in classified locations without additional certification requirements.

2. How does the armor on this 3300 NSv probe affect installation?
The armor provides excellent mechanical protection but requires careful routing to maintain the minimum bend radius of 25.4 mm (1.0 inch). Additionally, the armored cable is slightly stiffer than non-armored versions, so plan your cable path accordingly to avoid sharp bends.

3. Is the Bently Nevada 330909-00-13-05-01-05 compatible with existing 3300 RAM systems?
Yes, this 3300 NSv probe is fully interchangeable with previous 3300 RAM probes and extension cables. The mechanical and electrical compatibility ensures seamless upgrades without modifying your existing monitoring system.

4. Why does the unthreaded length option show 0.0 inches for this model?
The -00 unthreaded length option means this probe has no unthreaded section between the threads and the probe tip. This configuration is suitable for applications where the probe needs to be fully threaded into the mounting fixture for optimal positioning.

5. Can this armored 3300 NSv probe be used in temperatures below -34°C?
While the probe's operating range extends down to -52°C, we do not recommend sustained exposure below -34°C. The Viton O-ring seal may experience premature failure at these lower temperatures, potentially compromising the differential pressure sealing capability.
