The 32000-00-00-04-470-01-02 is a configuration variant from Bently Nevada within the 31000 series. This model is supplied without a probe or cable, offering maximum flexibility for users who already have preferred sensing elements. It includes a 40mm standoff adapter and a 470mm probe penetration depth, which suits machinery with substantial casing thickness.
This housing complies with the American Petroleum Institute (API) 670 Standard for externally mounted probe housings. Therefore, it provides reliable performance in critical turbomachinery monitoring applications. The external adjustment capability allows technicians to set the probe gap without opening the machine casing.
The product number 32000-00-00-04-470-01-02 reveals its specific options. The "00" probe option indicates that the probe is not required. Similarly, the "00" cable length option means the cable is also excluded. This configuration allows customers to supply their own compatible probes and cables.
The standoff adapter option "04" provides a 40mm extension, positioning the probe tip optimally within the measurement zone. Furthermore, the penetration option "470" delivers a 470mm depth, accommodating very thick walls or insulated casings. The fittings option "01" includes one M25 fitting and two plugs, which conform to metric conduit standards. Finally, the mounting thread option "02" is a 3/4-14 NPT thread, required when ordering the standoff adapter.
This housing carries the same robust certifications as other models in the 31000 series. It holds a Type 4X rating certified by the Canadian Standards Association (CSA), ensuring corrosion resistance and weatherproofing. Additionally, the IP66 rating verified by SC115582-1 (e) 106 guarantees protection against powerful water jets and dust ingress.
The CENELEC standard EN50014 rating confirms safe electrostatic dissipation for plastic materials in hazardous locations. Consequently, the 32000-00-00-04-470-01-02 is suitable for use in potentially explosive atmospheres such as refineries and chemical plants.
The housing body consists of glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers. This material offers excellent chemical resistance and maintains dimensional stability across a wide temperature range. The sleeve and retaining chain are fabricated from AISI 304 stainless steel, providing good corrosion resistance.
For the outer sleeve and exterior screws, Bently Nevada uses AISI 303 stainless steel. This grade delivers improved machinability and a smooth surface finish. The Neoprene O-ring creates a dependable seal against moisture and airborne contaminants. Together, these materials ensure long-term durability in harsh industrial settings.
This housing operates reliably between -51°C and +105°C (-60°F to +221°F). Such thermal capability makes it suitable for both cold climate installations and high-temperature processes.
Impact strength is another key feature. BASEEFA certified this housing to withstand two separate 4 Joule (3.0 ft·lb) impacts at -39°C and at 115°C. CSA also verified that samples withstand a 7 Joule (5.2 ft·lb) impact at ambient room temperature. This ruggedness protects the internal components from accidental blows during operation or maintenance.
The outer sleeve demonstrates substantial load-bearing ability. In standard testing, the sleeve was mounted horizontally on a test stand with the housing attached through an end hole. The assembly supported 912 N (205 lb) placed approximately 38 mm from the unsupported end. This strength ensures the 32000-00-00-04-470-01-02 remains stable under heavy vibration or external forces.
Installing the Bently Nevada 32000-00-00-04-470-01-02 requires proper preparation. Begin by cleaning the mounting hole on the machine casing thoroughly. Remove any burrs or sharp edges that might damage the O-ring. Apply a suitable thread sealant to the 3/4-14 NPT threads.
Next, thread the housing assembly into the casing opening. Ensure the 40mm standoff adapter is correctly positioned to achieve the desired probe tip location. Tighten the retaining nut to the recommended torque of 29.4 N·m (260 in·lb). Avoid over-torquing, which could cause thread damage or O-ring extrusion.
After securing the housing, install your own compatible 3300 XL 8 mm probe and cable assembly. Route the cable through the M25 fitting and connect it to the monitoring system. Finally, perform a gap adjustment using the external adjustment mechanism. Set the probe to the specified air gap based on the machine's operational requirements.
This housing is ideal for large turbines, compressors, and pumps with exceptionally thick casings. The 470mm penetration depth accommodates machines with thermal insulation blankets, double-walled construction, or extended bearing housings. It is also well-suited for thrust position monitoring and Keyphasor speed measurements.
Because of its IP66 and Type 4X ratings, the 32000-00-00-04-470-01-02 performs reliably in outdoor installations exposed to rain, snow, or dust storms. The M25 metric fitting makes it convenient for installations in regions following metric conduit standards. Therefore, this housing reduces maintenance frequency and extends probe life.

1. Why does this model come without a probe or cable?
The "00" options indicate that the probe and cable are not included. This allows users to supply their own compatible 3300 XL 8 mm probes or to replace only the housing in an existing installation.
2. What is the purpose of the 40mm standoff adapter?
The standoff adapter extends the probe tip beyond the housing face. This positions the probe correctly when the machine casing is thick or when internal obstructions exist.
3. Can I use this housing with a non-Bently Nevada probe?
Bently Nevada recommends using only genuine 3300 XL 8 mm probes for optimal performance and safety. Third-party probes may not achieve the same measurement accuracy or certification compliance.
4. What does the M25 fitting option mean?
The M25 fitting conforms to metric conduit standards. This is common in European and Asian installations. The housing includes one M25 fitting and two plugs for unused ports.
5. How do I adjust the probe gap after installation?
External adjustment is possible using the housing's built-in mechanism. You can adjust the gap without removing the housing or opening the machine casing, which minimizes downtime.
