The 31000-16-10-15-163-01-02 is a specialized housing from Bently Nevada for securing 3300 XL 8 mm proximity probes. This model includes a standoff adapter with a minimum length of 1.5 inches (38 mm). Additionally, it offers a probe penetration depth of 16.3 inches, which accommodates very thick machine casings.
This housing meets the American Petroleum Institute (API) 670 Standard for externally mounted probe housings. Therefore, it is an excellent choice for critical turbomachinery monitoring systems. The external adjustability feature allows technicians to set the probe gap without opening the machine.
The product number 31000-16-10-15-163-01-02 clearly defines each option selected. The "16" probe option specifies the 3300 XL 8 mm probe with a connector. The cable length option "10" provides a 1.0-metre (39-inch) cable, offering greater reach for remote junction boxes.
The standoff adapter option "15" is a critical feature for this model. It provides a minimum length of 1.5 inches, which elevates the probe tip to an optimal position. Moreover, the penetration option "163" delivers a 16.3-inch depth, suitable for casings with thick insulation or double walls. The fittings option "01" includes one 3/4-14 NPT fitting and two plugs. Finally, the mounting thread option "02" is a 3/4-14 NPT thread, required when using the standoff adapter.
The Bently Nevada 31000 housing carries robust protection certifications. It holds a Type 4X rating certified by the Canadian Standards Association (CSA). Furthermore, it has an IP66 rating verified by SC115582-1 (e) 106, ensuring protection against powerful water jets and dust ingress.
In addition, the CENELEC standard EN50014 rating confirms safe electrostatic dissipation for plastic materials in hazardous areas. This makes the 31000-16-10-15-163-01-02 suitable for use in potentially explosive atmospheres. Consequently, it meets the safety requirements of oil refineries, chemical plants, and gas processing facilities.
The housing body is made from glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic containing conductive fibers. This material provides excellent chemical resistance and dimensional stability. The sleeve and retaining chain are manufactured from AISI 304 stainless steel, offering good corrosion resistance.
For the outer sleeve and exterior screws, Bently Nevada uses AISI 303 stainless steel. This grade provides enhanced machinability and surface finish. The Neoprene O-ring ensures a reliable seal against moisture and contaminants. Together, these materials guarantee long service life even in harsh offshore or desert environments.
This housing operates reliably across a wide temperature range from -51°C to +105°C (-60°F to +221°F). Such thermal stability makes it suitable for both cryogenic and high-temperature processes.
Impact strength is another notable attribute. BASEEFA certified this housing to withstand two separate 4 Joule (3.0 ft·lb) impacts at -39°C and at 115°C. Samples of the housing and cover also passed a 7 Joule (5.2 ft·lb) impact test at ambient room temperature, verified by CSA. This ruggedness protects the internal probe from accidental blows during maintenance or operation.
The outer sleeve demonstrates significant load-bearing capability. In a typical test, 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 31000-16-10-15-163-01-02 remains stable even under heavy vibration or external forces.
Installing the Bently Nevada 31000-16-10-15-163-01-02 requires careful attention to detail. First, clean the mounting hole on the machine casing thoroughly. Remove any burrs or sharp edges that could damage the O-ring. Apply a suitable thread sealant to the 3/4-14 NPT fitting.
Next, thread the housing assembly into the casing opening. Ensure the 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). Over-torquing may cause thread damage or O-ring extrusion.
After securing the housing, connect the 1.0-metre probe cable to the monitoring system. The extra cable length simplifies routing to junction boxes or conduits. Finally, perform a gap adjustment using an external adjustment mechanism. Set the probe to the specified air gap based on the machine's operational requirements.
This housing excels in monitoring large turbines, compressors, and pumps with thick casings. The 16.3-inch penetration makes it particularly useful for machines with thermal insulation blankets or double-walled construction. It is also suitable for thrust position monitoring and Keyphasor speed measurements.
Because of its IP66 and Type 4X ratings, the 31000-16-10-15-163-01-02 performs well in outdoor installations exposed to rain, snow, or dust storms. The stainless steel components resist corrosion in coastal or chemical environments. Therefore, this housing reduces maintenance frequency and extends probe life.

1. Which probes work with this housing model?
This housing is specifically designed for Bently Nevada 3300 XL 8 mm proximity probes with connector options. It does not support other probe diameters.
2. What is the purpose of the standoff adapter?
The standoff adapter extends the probe tip beyond the housing face. This allows proper positioning when the machine casing is thick or has an internal obstruction.
3. Can this housing be used in hazardous areas?
Yes, it carries CENELEC EN50014 certification for electrostatic dissipation. It is suitable for installation in hazardous classified locations.
4. 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.
5. Is the 1.0-metre cable long enough for my application?
The 1.0-metre cable provides flexibility for connecting to nearby junction boxes. For longer distances, extension cables or intermediate junction boxes may be required.
