Bently Nevada 330907-05-30-50-12-00 Reverse Mount Probe

Bently Nevada 330907-05-30-50-12-00 3300 NSv Reverse Mount Probe

Product Introduction

The Bently Nevada 330907-05-30-50-12-00 belongs to the 3300 NSv series of reverse mount proximity probes. This particular model comes with M10X1 threads and a 5.0-meter total cable length. Additionally, it includes a miniature coaxial ClickLoc connector with FluidLoc cable for secure and reliable connections.

This probe offers significantly improved chemical resistance compared to the standard 3300 RAM probe. Therefore, it performs exceptionally well in process compressor environments where exposure to harsh media is common. Moreover, its side-view characteristics are superior to those of the 3000-series 190 probe at the same gap distance. Consequently, the 3300 NSv probe provides more accurate and stable measurements for critical turbomachinery protection.

Mechanical and Environmental Parameters

The 3300 NSv Reverse Mount Probe features a robust mechanical design for harsh industrial conditions. The probe tip uses Polyphenylene sulfide (PPS) material, while the probe case is constructed from AISI 304 stainless steel (SST). This combination ensures excellent durability and corrosion resistance.

Furthermore, the probe incorporates a Viton O-ring to seal differential pressure between the tip and the case. The operating and storage temperature range spans from -52°C to +177°C (-62°F to +351°F). However, exposing the probe to temperatures below -34°C (-30°F) for a sustained period may cause premature pressure seal failure. For installation, the recommended torque for reverse mount probes is 7.5 N•m (66 in•lb), with a maximum rated torque of 22.6 N•m (200 in•lb).

Key Features and Benefits

The Bently Nevada 3300 NSv probe offers several distinct advantages over conventional probes. First, the patented TipLoc molding method creates a robust bond between the probe tip and the probe body. This significantly enhances mechanical strength and reliability.

In addition, all components of the transducer system feature gold-plated brass ClickLoc connectors. These connectors lock firmly into place and effectively prevent the connection from loosening due to vibration. Meanwhile, the FluidLoc cable option provides additional protection against fluid ingress. For process compressor applications, the increased chemical resistance of the 3300 NSv probe is a critical benefit that ensures long-term stability.

Installation Guidelines

Proper installation is essential for achieving optimal performance from the 330907-05-30-50-12-00 probe.

First, verify that the mounting thread is M10X1 and that the maximum thread engagement is 15 mm. Next, ensure the target surface is clean and within the specified linear range of 0.25 to 1.75 mm. Then, set the gap to the recommended 1.0 mm (40 mils) for optimal linearity.

After that, route the 5.0-meter cable carefully to avoid sharp bends or mechanical stress. Connect the miniature coaxial ClickLoc connector by pushing it firmly until it clicks into place. Finally, use shielded triad cable for field wiring and keep the total extension length under 305 meters to avoid signal rolloff at high frequencies.
