The 330881-28-00-060-00-02 is a Bently Nevada PROXPAC XL self-contained proximity transducer system featuring an integrated 3300 XL Proximitor sensor and an 8mm probe with 60mm penetration. Fully compatible with industrial monitors, this type 4X and IP66 rated polyphenylene sulfide (PPS) unit works seamlessly without extension cables to deliver secure field wiring and stable non-contact machinery vibration monitoring in hazardous locations.
Features and Benefits
Integrated Design: Combines the probe and Proximitor in one housing, eliminating extension cables and separate enclosures.
Rugged Construction: Features a glass-reinforced PPS thermoplastic housing for high strength and electrostatic dissipation.
Environmental Protection: IP66 and Type 4X rated, offering superior protection in harsh, severe-duty environments.
Simplified Wiring: Allows direct field wiring from the monitor to the assembly, saving installation time and costs.
High Performance: Delivers a 7.87 V/mm (200 mV/mil) scale factor with ±5% interchangeability error over a 2 mm linear range.
Flexible Power: Operates on -17.5 to -26 Vdc supply, compatible with various monitoring system configurations.
Application
Self-Contained Machine Casing Installations: Eliminates external intermediate extension cables and separate housings by integrating the Proximitor sensor directly into the weather-proof probe junction enclosure.
Aggressive and Severe Industrial Environments: Deployed on multi-stage pumps, cooling tower fans, or gas turbines where high humidity, hose-directed washdowns, or chemical exposure demands IP66 or Type 4X physical isolation.
Hazardous Area Vibration Monitoring: Intended for Zone 0/Zone 2 or Division 1/Division 2 industrial environments where certified explosive atmosphere protection (ATEX/IECEx/cNRTLus) is mandatory.

- FAQ
Q1: What makes the PROXPAC XL a "self-contained" system?
A1: It integrates both the 8 mm probe and the 3300 XL Proximitor sensor into a single housing, eliminating the need for extension cables and separate sensor enclosures.
Q2: What material is the PROXPAC XL housing made of?
A2: The housing is constructed from Polyphenylene Sulfide (PPS), an advanced thermoplastic reinforced with glass and conductive fibers for strength and electrostatic dissipation.
Q3: What are the power requirements for this assembly?
A3: It requires a -17.5 Vdc to -26 Vdc power supply without barriers, with a maximum current consumption of 12 mA.
Q4: What is the Incremental Scale Factor (ISF) and its accuracy?
A4: The ISF is 7.87 V/mm (200 mV/mil) with an interchangeability error of ±5% over the full linear range.
Q5: What environmental ratings does the housing have?
A5: The PROXPAC XL housing is rated Type 4X and IP66, providing extra protection in severe environments.
