Bently Nevada 330880-00-00-000-03-02 PROXPAC XL English Proximity Transducer Assembly
English housing configuration with Proximitor Sensor and no probe
Product Description
330880-00-00-000-03-02 is an English-dimension PROXPAC XL proximity-transducer assembly configured without a probe. The housing contains the 3300 XL Proximitor Sensor, allowing field wiring to run directly from the protected assembly to the monitor.
Its code records no standoff adapter and no probe sleeve. Fitting option 03 supplies one 3/4-14 NPT fitting, one 3/4-14 to 1/2-14 NPT stainless-steel reducer and two plugs; mounting option 02 is the 3/4-14 NPT outer-sleeve thread selection.
Because 330880-00-00-000-03-02 does not include the probe, the receiving installation must supply the correct 3300 XL 8 mm sensing arrangement before the channel is commissioned.

Integrated Sensor Connectivity
The Proximitor Sensor is mounted inside the PROXPAC XL cover, so no extension cable is used between the probe and the sensor in a complete assembly. Field wiring leaves the housing and runs to the monitor through the selected conduit fitting arrangement.
This configured unit supplies the protected sensor housing and fittings but no probe, standoff or probe sleeve. Add only a mechanically compatible 3300 XL 8 mm probe arrangement, then keep the probe cable, sensor input and monitor wiring separated from adjacent transducer channels.
Enclosure Protection & Moisture Control
Enclosure Protection & Moisture Control in practice
The glass-reinforced conductive PPS enclosure is rated Type 4X and IP66 when its cover, conduit entries and sealing parts are assembled correctly. Its plastic construction resists industrial weather exposure while the conductive fibers support the electrical design.
Seal unused openings with the supplied plugs, tighten the selected fitting arrangement and prevent moisture from entering through field wiring or an incomplete probe interface. After closing the housing, inspect the gasket and verify the channel output from the monitor side.
Frequently Asked Questions
Why does 330880-00-00-000-03-02 produce no measurement after the housing is wired to the monitor?
This configuration contains the enclosed Proximitor Sensor but selects no probe, standoff or probe sleeve. Install a mechanically compatible 3300 XL 8 mm probe arrangement, connect it to the internal sensor and then verify the monitor field wiring.
What should be checked if the signal from 330880-00-00-000-03-02 weakens or becomes noisy over a long field-wiring run?
Use three-conductor shielded wiring and keep the run within 305 m while separating it from power conductors and adjacent channels. Confirm shield termination, the 50 ohm output path and the monitor input before changing the probe gap.
How can water or dust entry into 330880-00-00-000-03-02 be prevented in an exposed installation?
Seat the cover gasket correctly, tighten the selected conduit fitting and close unused entries with the supplied plugs. Type 4X and IP66 protection depends on the completed enclosure, so an open probe interface or loose entry defeats the rating.
Should an external extension cable be added between the probe and 330880-00-00-000-03-02?
The Proximitor Sensor is already mounted inside the PROXPAC XL housing, so the probe connects directly to that internal sensor. Field wiring then runs from the housing to the monitor; adding an unplanned extension changes the intended signal chain.
What should a buyer verify when the existing conduit hardware does not match 330880-00-00-000-03-02?
Option 03 provides one 3/4-14 NPT fitting, a stainless reducer to 1/2-14 NPT and two plugs. Compare those interfaces with the site conduit before installation and use the correct sealed arrangement rather than leaving an entry partially adapted.
Our Advantages
Supply strengths
Four capabilities that support industrial spare-parts buyers
A large stock base supports faster availability checks, while global sourcing routes help locate products that are not immediately available. Competitive pricing and efficient logistics give buyers practical choices for both planned maintenance and urgent shutdown work.
Product condition, delivery timing and warranty terms are communicated before shipment so the order can be evaluated as a complete purchase.
