Bently Nevada 32000-28-05-00-035-01-02 Probe Housing

32000-28-05-00-035-01-02 | Bently Nevada Metric Probe Housing

Product Introduction

The Bently Nevada 32000-28-05-00-035-01-02 is a compact metric proximity probe housing that includes a 3300 XL 8 mm probe with multiple agency approvals. This configuration is ideal for applications requiring certified instrumentation for use in regulated industries such as oil and gas, power generation, and chemical processing.

Notably, this housing is supplied without a standoff adapter, resulting in a shorter overall assembly. This makes it particularly suitable for installations with limited space or where the machine casing allows direct mounting. The 35 mm penetration depth provides sufficient insertion for most radial vibration and axial position measurements while maintaining a low profile.

Technical Specifications

The Bently Nevada 32000-28-05-00-035-01-02 delivers a well-defined configuration tailored for specific monitoring needs. The model number encodes each critical parameter:

• Probe Option (28): Includes 3300 XL 8 mm probe with multiple agency approvals (e.g., CSA, ATEX, IECEx).

• Probe Cable Length (05): 0.5 meters (20 inches).

• Standoff Adapter (00): No standoff adapter (direct mounting).

• Probe Penetration (035): 35 mm insertion depth through the housing.

• Fittings (01): One M25 fitting and two plugs for conduit connections.

• Mounting Thread (02): 3/4-14 NPT (required if ordering the standoff adapter, though not applicable here).

Furthermore, this housing provides outstanding environmental protection. It carries Type 4X certification from the Canadian Standards Association (CSA), ensuring corrosion resistance and weatherproof performance. The IP66 rating, verified by SC115582-1 (e) 106, guarantees complete protection against dust ingress and powerful water jets. Additionally, the housing meets CENELEC standard EN50014 for electrostatic dissipation of plastic materials used in hazardous locations.

Mechanical and Environmental Ratings

The 32000-28-05-00-035-01-02 is built from high-grade materials to withstand challenging industrial conditions. The housing body uses glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic containing conductive fibers, which delivers excellent strength and chemical resistance.

For mechanical durability, the sleeve and retaining chain are constructed from AISI 304 stainless steel, while the outer sleeve and exterior screws use AISI 303 stainless steel. The Neoprene® O-ring ensures a reliable seal against moisture and contaminants, protecting the internal probe and cable connections.

Impact resistance is a key feature of this housing. BASEEFA certified it to endure two separate 4 Joule (3.0 ft·lb) impacts at both -39°C (-38°F) and 115°C (239°F). Moreover, CSA verified that housing and cover samples withstand a 7 Joule (5.2 ft·lb) impact at ambient room temperature, ensuring robustness during installation and operation.

The operating temperature range spans from -51°C to +105°C (-60°F to +221°F) , accommodating a broad spectrum of applications from cold outdoor environments to high-temperature machinery compartments.

Installation Guidance

Installing the Bently Nevada 32000-28-05-00-035-01-02 is straightforward due to its compact design. Begin by verifying that the mounting surface has the correct 3/4-14 NPT thread. Since no standoff adapter is included, the housing mounts directly to the machine casing.

Next, route the probe cable through the housing and secure it using the M25 fitting, which accommodates standard conduit sizes. Adjust the probe to achieve the 35 mm penetration depth, then lock the assembly in place.

Finally, connect the system to a compatible Bently Nevada proximitor or monitoring system. Always check the gap voltage before final tightening to ensure the probe operates within its linear range for accurate measurements.

Frequently Asked Questions

Q1: What does "multiple approvals" mean for the probe option?
A1: Option code 28 indicates the 3300 XL 8mm probe carries certifications such as CSA, ATEX, and IECEx for use in hazardous areas.

Q2: Why is there no standoff adapter included?
A2: Option code 00 means no standoff adapter is required, making this housing suitable for direct mounting on machine casings with limited space.

Q3: What is the 35mm penetration depth suitable for?
A3: The 35mm depth is ideal for radial vibration measurements on smaller machinery or where casing thickness is minimal.

Q4: Can I add a standoff adapter later?
A4: Yes, you can add a standoff adapter, but the 3/4-14 NPT mounting thread must be used, and the penetration depth may change accordingly.

Q5: Is this housing compatible with non-Bently Nevada monitoring systems?
A5: While designed for Bently Nevada proximitors, the housing can be adapted to other systems with compatible interface requirements.
