Providing robust physical shielding for critical rotating machinery sensors, the Bently Nevada 330801-16-10-110-06-02 is a specialized PROXPAC XL proximity transducer housing assembly. This component protects and positions a 3300 XL 8 mm proximity probe directly through the casing of high-speed industrial machinery, enabling continuous, high-accuracy eddy current displacement and vibration measurements. Built to withstand extreme environmental stresses, this assembly isolates delicate sensor connections from chemical exposure, high moisture, and mechanical impacts in hazardous operating zones.
| Option Code | Configuration Parameter | Selected Specification |
|---|---|---|
| 16 | Probe and Approvals Option | 3300 XL 8 mm Probe |
| 10 | Standoff Adapter Option | 100 mm |
| 110 | Probe Penetration Option | 110 mm |
| 06 | Fittings Option (Supplied as Kit) | One 3/4-14 NPT fitting, one 3/4-14 NPT to 1/2-14 NPT SST reducer, 2 plugs |
| 02 | Mounting Thread Option | 3/4-14 NPT (Required for standoff adapter) |
| Manufacturer | Bently Nevada |
| Model Series | PROXPAC XL Proximity Transducer Assembly |
| Probe System Compatibility | 3300 XL Series (8 mm) |
| Standoff Length | 100 mm |
| Penetration Depth | 110 mm |
| Mounting Thread Connection | 3/4-14 NPT |
| Housing Material | Corrosion-resistant metal alloy with protective seals |
| Country of Origin | United States (U.S.A.) |
| Shipping Weight | 2.5 kg |
| Package Dimensions (Calculated) | 320 mm x 180 mm x 140 mm |
This vintage PROXPAC model has been formally succeeded by the updated 330881-16-10-110-06-02 assembly. The replacement model maintains identical critical dimensional and mechanical interface footprints, allowing seamless field swaps. However, the legacy 330801 internal physical mounting tolerances should be verified if reusing custom field bushings or non-standard probe configurations.
Ensure thread compounds applied to the 3/4-14 NPT mounting adapter are chemically compatible with machine casing fluids. Under high-temperature operations, local heating can cause mechanical binding inside the standoff adapter. Additionally, verify that the total insertion length (standoff + penetration) matches the design gap clearance to avoid mechanical contact with the rotating shaft during startup.
When routing coaxial cable from the internal 3300 XL probe through the conduit fittings, maintain a minimum bend radius of 25.4 mm (1.0 inch). Kinking or crushing the coaxial transmission line during tight packaging inside the PROXPAC housing will cause local impedance variations, directly degrading transducer measurement linearity and causing diagnostic errors in the connected proximitor monitor.
Carefully thread the 3/4-14 NPT standoff adapter into the machine casing port, utilizing an appropriate anti-seize or thread sealant compatible with the operating medium.
Adjust the penetration depth of the internal 3300 XL 8 mm probe assembly using the calibration locknut, ensuring exact clearance distance from the target surface as verified by a digital voltmeter.
Route the coaxial cable smoothly through the NPT conduit fittings and reducers, securing all fluid-tight plugs to guarantee an IP-rated environmental seal.
