Bently Nevada 330909-00-80-05-02-00 3300 NSv Proximity Probe

Product Introduction

The Bently Nevada 330909-00-80-05-02-00 is a 3300 NSv proximity probe designed for shaft vibration and position measurements on rotating machinery. It belongs to the 3300 NSv proximity transducer family (330901 / 330902 / 330908 / 330909) and features a 3/8-24 UNF thread with armor for mechanical protection of the probe cable. The probe case is machined from AISI 304 stainless steel (SST) and the tip is made of polyphenylene sulfide (PPS), a combination that stands up to the demands of continuous industrial service. Manufactured in the U.S.A., this probe is a genuine Bently Nevada component.

Parameter Analysis

The ordering string of the 330909-00-80-05-02-00 encodes every physical characteristic of the probe. The 00 unthreaded length option means the threaded section runs the full case length, while the 80 option gives an overall case length of 8.0 inches. The 05 total length option provides 0.5 metre (20 inches) from probe tip to connector, and the 02 option specifies the miniature coaxial ClickLoc connector with standard 75 Ω FEP-insulated cable. The final 00 option indicates that no additional agency approval is required for this variant.

Correct installation torque is important for long-term reliability. For standard 3/8-24 or M10X1 probe cases, the maximum rated torque is 33.9 N·m (300 in·lb) with a recommended value of 11.3 N·m (100 in·lb); when only the first three threads are engaged, the maximum is 22.6 N·m (200 in·lb) with 7.5 N·m (66 in·lb) recommended. The maximum length of thread engagement for a 3/8-24 case is 0.563 in. Note that sustained exposure of the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal.

Application Scenarios

3300 NSv proximity probes are used for radial and axial shaft position, vibration, and speed measurements on turbines, compressors, pumps, fans, and other critical rotating equipment. The compact 3300 NSv design suits installations where a conventional probe is too large, and the armored cable construction of the 330909-00-80-05-02-00 provides extra protection in areas where the cable is exposed to abrasion or mechanical contact. The ClickLoc connector allows the probe to be mated with a matching 3300 NSv extension cable to reach the Proximitor in a safe location.

Installation Guide

Before installation, confirm that every option digit of the probe matches your system design requirements. Thread the probe into the tapped hole using the 3/8-24 UNF thread, keeping thread engagement within the 0.563 in maximum, and tighten to the recommended torque rather than the maximum rated torque. Mate the miniature coaxial ClickLoc connector to the matching extension cable until it clicks, then set the probe gap according to the electrical requirements of the associated 3300 NSv Proximitor. Always verify the measured gap voltage against your system documentation before returning the machine to service.

Compatibility

The 330909-00-80-05-02-00 is engineered for the 3300 NSv proximity transducer system and connects through the miniature coaxial ClickLoc interface to 3300 NSv extension cables. Bently Nevada probes and cables of the same part number are fully interchangeable, so a replacement probe can be fitted without re-engineering the measurement loop. TenBN also supplies the matching extension cables and Proximitors for a complete, consistently sourced measurement chain.

Maintenance Advice

Inspect the probe tip, threads, and armor at each maintenance opportunity for wear, corrosion, or mechanical damage. Check that connector torque has not loosened in service and that the ClickLoc connection remains secure. Keep the probe within its -52°C to +177°C operating envelope, and avoid sustained exposure below -34°C, which can degrade the Viton pressure seal. When storing spare probes, keep them in their original packaging within the same temperature limits.

Procurement Advice

Because each option digit changes the physical fit of the probe, always verify the complete part number against your machine’s bill of materials before ordering. TenBN stocks genuine Bently Nevada 3300 NSv components and can supply the full datasheet and service documentation for this model.

Frequently Asked Questions

What does each option digit in 330909-00-80-05-02-00 mean?

The digits define the hardware: 00 = 0.0 in unthreaded length, 80 = 8.0 in overall case length, 05 = 0.5 metre total length, 02 = miniature coaxial ClickLoc connector with standard cable, and 00 = no agency approval required.

Is this probe armored?

Yes. This variant is supplied with armor, which protects the probe cable against abrasion and mechanical damage in exposed installations.

Which connector does the probe use?

It uses a miniature coaxial ClickLoc connector on a standard 75 Ω coaxial cable with FEP insulation, which mates with matching 3300 NSv extension cables.

What is the operating temperature range?

The probe operates and can be stored from -52°C to +177°C (-62°F to +351°F). Sustained exposure below -34°C (-30°F) should be avoided as it may cause premature failure of the pressure seal.

Do you supply the matching extension cable and Proximitor?

Yes. TenBN carries the 3300 NSv proximity family, including extension cables and Proximitors, so the complete measurement chain can be sourced from a single supplier.
