Description
330881-01-00-000-00-02: 3300 XL metric PROXPAC XL integrated proximity transducer assembly, configured without a probe (Option 01, Proximitor sensor with Multiple Approvals) and without a probe sleeve or standoff adapter. This specific configuration serves as a spare or base housing unit containing a built-in 3300 XL Proximitor sensor certified for multiple hazardous area approvals, but does not include the physical 8 mm probe, standoff adapter, or outer sleeve assembly. It features no conduit fittings (Option 00, supplied with two plugs and two washers) and is configured with a 3/4-14 NPT mounting thread (Option 02).
The PROXPAC XL series combines a proximity probe and a Proximitor sensor into a single, self-contained field housing. This integrated design eliminates the requirement for separate Proximitor housings and intermediate extension cables, allowing field wiring to connect directly from the monitoring system to the housing. The housing is constructed from glass-reinforced, conductive polyphenylene sulfide (PPS) thermoplastic to resist severe industrial environments, dissipate electrostatic charges, and provide Type 4X and IP66 protection.
Features
- Integrated Design: Combines a built-in 3300 XL Proximitor sensor inside a single housing, eliminating intermediate cables and separate mounting enclosures.
- Option 01 Sensor Configuration: Supplied with a metric Proximitor sensor rated for multiple global hazardous area approvals, without a pre-installed probe.
- Option 000 Sleeve: Configured without a physical probe sleeve, allowing custom installation or retrofitting into existing sleeve hardware.
- Conductive Thermoplastic Housing: Made of advanced polyphenylene sulfide (PPS) containing glass and conductive fibers to strengthen the body and dissipate static.
- Option 02 Mounting Thread: Standard 3/4-14 NPT mounting interface.
- Industrial-Grade Ingress Protection: Verified Type 4X and IP66 environmental rating for protection in severe outdoor or marine process conditions.
Applications
The PROXPAC XL integrated transducer assembly is used for non-contact shaft vibration, axial position, and speed measurements on rotating machinery such as steam turbines, gas turbines, compressors, pumps, and generators. This specific configuration is suited for applications where the housing or Proximitor sensor needs replacement, or where custom probe sleeves and probe elements are mounted separately in the field.

Installation Guidelines
-
Wiring and Conduit: Field wiring connects directly inside the PROXPAC XL housing cover to the integrated Proximitor sensor. Use twisted, shielded 3-conductor field wiring (such as 1.0 mm2 / 18 AWG).
-
Moisture Prevention: Ensure proper sealing of conduit entries. Take precautions to prevent moisture from traveling through conduit. Use the provided blanking plugs to seal unused housing openings.
-
Grounding: A grounding liner is included within the housing. Ensure the grounding system is connected per certified drawings (e.g., drawing 141092 for intrinsically safe or 140979 for non-incendive installations).
-
Thread Sealant: Apply appropriate thread sealant to the 3/4-14 NPT threads (Option 02) before installation to maintain housing ingress ratings.
