Bently Nevada 330909-00-60-50-02-05 NSv Probe

Bently Nevada 330909-00-60-50-02-05 3300 NSv Armored Proximity Probe

Product Introduction

The Bently Nevada 330909-00-60-50-02-05 belongs to the 3300 NSv series of proximity probes and includes stainless steel armor for enhanced cable protection. Engineers select this model when they need a longer case length for deep mounting holes or recessed targets. This probe offers a 5.0 meter total length with a 3/8-24 UNF thread and a 6.0 inch overall case length. Its miniature coaxial ClickLoc connector provides a secure signal connection, while the standard cable construction keeps the assembly flexible. The probe tip uses Polyphenylene sulfide (PPS), a material that resists chemicals and wear effectively. Additionally, the case is machined from AISI 304 stainless steel, and the armor adds extra mechanical durability. With multiple agency approvals, this probe meets global industrial safety standards. Its 75Ω coaxial FEP cable maintains signal quality over long distances. This sensor works exclusively with compatible NSv Proximitor sensors for optimal system performance.

Key Technical Specifications

The Bently Nevada 330909-00-60-50-02-05 delivers precise measurements with its robust design. Its probe tip material is PPS, which offers excellent dimensional stability and chemical resistance. The case material is AISI 304 SST, while the armor provides mechanical ruggedness for the cable. The probe cable is a 75Ω coaxial type with FEP insulation, available in total lengths of 0.5, 1, 5, or 7 meters. This particular model comes with a 5.0-meter cable. The DC resistance from the center conductor to the outer conductor measures 5.3 ± 0.7 ohms. Furthermore, the operating and storage temperature range spans from -52°C to +177°C. However, note that exposing the probe to temperatures below -34°C for extended periods may reduce the pressure seal's service life. The probe case thread is 3/8-24 UNF, with a maximum thread engagement length of 0.563 inches. The maximum rated torque for the case is 33.9 N•m, while the recommended torque is 11.3 N•m. For the first three threads, the maximum torque is 22.6 N•m and the recommended torque is 7.5 N•m. For connector-to-connector connections, finger-tight is recommended, with a maximum torque of 0.565 N•m.

Mechanical and Environmental Ratings

This armored NSv probe handles differential pressure sealing via a Viton O-ring between the tip and case. Bently Nevada does not pressure-test each unit before shipment, but the design effectively seals against process pressure. The probe's pressure rating applies to static and dynamic conditions typical in compressor and turbine applications. Its temperature rating of -52°C to +177°C covers most industrial environments, including extreme cold and high-heat areas. Moreover, the armor provides extra resistance against physical damage, making it suitable for retrofit projects or locations with cable exposure risks. The unthreaded length option is 0.0 inches, and the overall case length is 6.0 inches. The total length option is 5.0 meters, which must match the compatible NSv Proximitor sensor. Therefore, do not use this probe with sensors designed for other cable lengths. The probe cable's FEP insulation resists high temperatures and chemicals, ensuring long-term reliability. Its coaxial design maintains signal integrity with appropriate shielding. The connector type is a miniature coaxial ClickLoc, which locks positively to prevent accidental disconnection.

Installation Guidelines

Proper installation of the Bently Nevada 330909-00-60-50-02-05 ensures accurate readings and long service life. First, clean the mounting surface and threads thoroughly before installation. Apply a suitable anti-seize compound to the 3/8-24 UNF threads to prevent galling. Next, thread the probe into the mounting hole by hand until finger-tight. Then, use a torque wrench to tighten it to the recommended 11.3 N•m. For the first three threads, limit torque to 7.5 N•m. Do not exceed the maximum torque of 33.9 N•m, as this could damage the case or threads. For the connector, tighten it finger-tight only, with a maximum of 0.565 N•m. Ensure the cable bend radius stays above 25.4 mm to avoid damaging the internal conductors. Additionally, route the cable away from high-voltage wires and heat sources. Secure the cable using appropriate clamps or ties, but do not overtighten. When installing multiple probes, maintain adequate spacing to avoid cross-talk. Finally, connect the probe to its compatible NSv Proximitor sensor. Verify the air gap using a calibration fixture before startup. After installation, perform a system check to confirm output voltage matches the target gap.

Frequently Asked Questions (FAQ)

1. What makes the 330909-00-60-50-02-05 different from standard 3300 XL probes?
The Bently Nevada 330909-00-60-50-02-05 belongs to the 3300 NSv series, which features a 6.0 inch overall case length and 3/8-24 UNF threads. It also uses a coaxial cable instead of triaxial and has different DC resistance specifications.

2. Can I use this probe with a 7-meter Proximitor sensor?
No. This 5.0-meter probe works exclusively with the compatible NSv Proximitor sensor designed for 5.0-meter cables. Using it with other lengths will cause calibration errors.

3. What is the recommended torque for the 3/8-24 UNF threads?
The recommended installation torque is 11.3 N•m (100 in•lb) for full thread engagement. For the first three threads, use 7.5 N•m (66 in•lb). The maximum allowable torque is 33.9 N•m (300 in•lb).

4. Why does this probe have a longer 6.0 inch case length?
The 6.0 inch overall case length allows installation in deep mounting holes or applications where the target is recessed. This extended reach ensures proper gap positioning.

5. How should I store this probe if not used immediately?
Store the probe in its original anti-static bag in a clean, dry area within the -52°C to +177°C temperature range. Avoid areas with extreme humidity or corrosive fumes to preserve the O-ring and cable insulation.
