Bently Nevada 31000-28-05-70-066-00-02 Housing

Bently Nevada 31000-28-05-70-066-00-02 31000 Proximity Probe Housing

Product Introduction

The Bently Nevada 31000-28-05-70-066-00-02 is a fully assembled 31000 series probe housing. This complete package includes the probe, cable, standoff, and housing in one unit. For instance, many customers choose this all-in-one 31000 housing for turbine monitoring, compressor protection, and pump vibration systems.

This model 31000-28-05-70-066-00-02 comes with a 3300 XL 8 mm probe that carries multiple agency approvals. The probe cable length is 0.5 meters, which suits short-run installations. Additionally, the 7.0-inch standoff adapter positions the probe correctly for optimal gap settings. The 6.6-inch probe penetration ensures the tip reaches the target surface accurately.

Since this version uses a 3/4-14 NPT mounting thread, it fits standard pipe fittings seamlessly. The housing does not include fittings (option 00), so you can source your own connectors. This flexibility allows customization for your specific piping configuration.

Technical Specifications

The Bently Nevada 31000-28-05-70-066-00-02 features a glass-reinforced PPS thermoplastic body with conductive fibers. This material provides excellent electrostatic dissipation for hazardous areas. Meanwhile, the sleeve and retaining chain are constructed from AISI 304 stainless steel. The outer sleeve and exterior screws use AISI 303 stainless steel for enhanced corrosion protection.

A Neoprene® O-ring seals the sleeve-to-housing interface. Furthermore, the internal probe seal uses a Viton® O-ring for reliable differential pressure sealing. The recommended retaining nut torque is 29.4 N·m (260 in·lb) . Proper torque application ensures a dependable seal against moisture and dust ingress.

For protection, this housing achieves CSA Type 4X certification and IP66 verification. It also meets CENELEC EN50014 for electrostatic dissipation. Consequently, it performs reliably in outdoor, wash-down, and hazardous area installations.

Mechanical and Environmental Ratings

This housing demonstrates exceptional impact resistance. BASEEFA certified it to withstand two separate 4 Joule impacts at -39°C and at 115°C. Moreover, CSA verified its ability to endure a 7 Joule impact at ambient temperature. Such durability guarantees stable operation in harsh industrial conditions.

The temperature rating spans from -51°C to +105°C (-60°F to +221°F). Therefore, it supports most industrial applications across diverse climates. The housing also showed mechanical strength by supporting 912 N (205 lb) in a cantilever test configuration.

Nevertheless, this housing is not designed for pressurized environments. It seals effectively against hose-directed water per NEMA 4X and IP66. However, it cannot resist internal or external pressure. For pressure seal testing, please contact our custom design department.

Installation Guidelines

Follow these steps to install the Bently Nevada 31000-28-05-70-066-00-02 correctly:

• Mounting preparation : Clean the 3/4-14 NPT mounting hole thoroughly. Then apply a suitable thread sealant to prevent leakage.

• Housing positioning : Insert the housing into the mounting hole. Next, adjust the standoff adapter to achieve the desired probe tip gap.

• Cable management : Route the 0.5-meter probe cable carefully. Avoid sharp bends near the connector area.

• Retaining nut torque : Apply 29.4 N·m (260 in·lb) to the retaining nut. Use a calibrated torque wrench for accurate results.

• Gap verification : Measure the air gap between the probe tip and target surface. A typical gap ranges from 1.5 mm to 2.5 mm.

After installation, perform a full system calibration. Then verify the output voltage matches your monitoring system requirements. Finally, secure all cable connections before starting your machinery.

Frequently Asked Questions

1. Does the 31000-28-05-70-066-00-02 include the probe and cable?
Yes, this Bently Nevada 31000-28-05-70-066-00-02 is a complete assembly. It includes the 3300 XL probe (option 28) and a 0.5-meter cable (option 05).

2. What agency approvals does the included probe carry?
The probe option 28 indicates multiple approvals. These typically include CSA, ATEX, and IECEx for hazardous area use.

3. Why does this housing have no fittings (option 00)?
The fittings option 00 means the housing ships without connectors. Therefore, you can purchase your own fittings to match your existing piping system.

4. Can I use this housing with a different probe length?
The housing accepts standard 3300 XL 8 mm probes. However, the 6.6-inch penetration is fixed for this model. For other depths, consider a different configuration.

5. Is this housing suitable for submersible applications?
No, this 31000 housing is not rated for submerged use. It seals against hose-directed water per IP66 but cannot resist continuous immersion or internal pressure.
