Bently Nevada 32000-28-05-06-020-07-02 Probe Housing

32000 Metric Proximity Probe Housing with Standoff by Bently Nevada

Product Introduction

The Bently Nevada 32000-28-05-06-020-07-02 provides a complete mounting solution for proximity probes requiring a standoff adapter. This configuration supports the 3300 XL 8 mm probe and includes a 60 mm standoff, making it suitable for applications where the probe needs to be positioned further from the mounting surface. Manufactured in the U.S.A., this housing ensures dependable sensor protection in critical machinery monitoring.

This housing features a glass-reinforced PPS thermoplastic body with conductive fibers. The material choice delivers excellent mechanical strength and electrostatic dissipation properties. Meanwhile, the sleeve and retaining chain use AISI 304 stainless steel, while the outer sleeve and exterior screws are crafted from AISI 303 stainless steel. This combination offers superior corrosion resistance and long-term durability.

The model comes with a 0.5 m (20 in) probe cable, which is shorter than other variants for installations with limited space. It also includes one PG21 x M20 fitting and two plugs. Therefore, you receive flexible connection options for different cable entry requirements.

Technical Specifications

This configuration, 32000-28-05-06-020-07-02, includes several distinct options. The probe penetration measures 20 mm, which is shallower compared to other variants. The 60 mm standoff adapter (option 06) positions the probe further from the housing base. The mounting thread is 3/4-14 NPT, which is mandatory when ordering the standoff adapter option.

The protection ratings remain industry-leading. It holds Type 4X certification from CSA, ensuring resistance to corrosion and moisture. Additionally, the IP66 rating has been verified through testing, guaranteeing protection against dust ingress and powerful water jets. The housing also complies with CENELEC standard EN50014 for electrostatic dissipation of plastic materials in hazardous areas.

Impact strength testing confirms its ruggedness. BASEEFA certified it to withstand two separate 4 Joule impacts at extreme temperatures of -39°C and 115°C. Furthermore, CSA verified its ability to withstand a 7 Joule impact at room temperature. This makes it exceptionally robust for demanding industrial environments.

Mechanical & Environmental Ratings

The operating temperature range spans from -51°C to +105°C. This broad range allows deployment in both freezing outdoor conditions and high-heat processing areas. The Neoprene® O-ring provides reliable sealing, maintaining the housing's environmental integrity over its service life.

This housing suits applications in oil and gas, power generation, and heavy manufacturing. For instance, it works effectively on steam turbines, centrifugal compressors, and large pumps. The standoff adapter allows the sensor to reach optimal measurement positions, particularly useful when mounting surfaces are uneven or when thermal isolation is needed.

Installation Guidelines

Installing this housing requires careful attention to the standoff adapter. First, thread the 60 mm standoff securely into the mounting surface. Next, attach the housing body to the standoff using the 3/4-14 NPT thread. Apply appropriate thread sealant to prevent leakage and ensure a secure fit.

Then, insert the 3300 XL 8 mm probe into the housing until the penetration depth reaches 20 mm. Verify the probe positioning using appropriate measurement tools. After that, route the probe cable through the PG21 x M20 fitting. Finally, use the provided plugs to seal any unused openings. This ensures the IP66 rating is maintained after installation.
