Description

330881-28-04-090-03-02: This configuration of the PROXPAC XL metric integrated transducer combines a 3300 XL 8 mm proximity probe and an integrated Proximitor sensor inside a self-contained, glass-reinforced Polyphenylene Sulfide (PPS) housing. This specific variant is pre-configured with a 3300 XL 8 mm probe that features certified hazardous area multiple approvals (Option 28), a 40 mm standoff adapter (Option 04), a 90 mm probe penetration sleeve (Option 090), an M20 cable fitting with two sealing plugs (Option 03), and a 3/4-14 NPT mounting thread (Option 02).

By housing the Proximitor sensor directly in the casing lid, this integrated assembly eliminates the need for an external extension cable and separate Proximitor junction boxes. This simplifies installation, minimizes potential connector point failures, and facilitates fast external probe adjustment on rotating machinery. The conductive fiber construction of the PPS housing effectively dissipates electrostatic charges, while the overall design achieves a robust Type 4X and IP66 rating for reliability in harsh industrial environments.

Features

• Hazardous Area Certified (Option 28): Equipped with a 3300 XL 8 mm probe carrying Multiple Approvals for Zone and Division classified applications.
• Adjustable Mounting Offset (Option 04): Features a 40 mm metric standoff adapter to accommodate specific machinery case dimensions.
• Precise Probe Penetration (Option 090): Built with a 90 mm probe penetration depth to ensure accurate proximity measurements on the target shaft.
• Cable Entry Fitting (Option 03): Supplied with a protective fitting kit containing one M20 conduit adapter and two blanking plugs.
• Secure Mounting Threads (Option 02): Integrates a 3/4-14 NPT outer sleeve thread structure for mounting alignment.
• Self-Contained Architecture: Integrates the probe and Proximitor sensor into a single unit, allowing direct connection to field wiring.
• Corrosion-Resistant Housing: Advanced polyphenylene sulfide (PPS) thermoplastic housing with conductive fibers prevents static buildup and withstands severe industrial environments.

Applications

The integrated transducer is designed for several critical industrial applications:

• Shaft dynamic vibration and axial position measurements on rotating machinery such as pumps, fans, and small compressors.
• Harsh environmental monitoring locations requiring Type 4X and IP66 moisture and particulate protection.
• Hazardous industrial environments requiring intrinsically safe (Ex ia) or non-sparking (Ex nA/Ex ec) installations.

Installation Guidelines

• Electrostatic Protection: Verify that the grounding liner and retaining plate are properly aligned and grounded during mounting to prevent static electricity discharge.
• Environmental Sealing: Use the provided M20 cable fitting and seal all unused conduit entry holes with the supplied plastic blanking plugs to maintain the housing IP66 rating.
• Physical Offset Adjustment: The threaded outer sleeve allows an adjustment range of plus or minus 12.7 mm (0.5 in) from the nominal mounting position to achieve precise probe-to-target gapping.
• Torque Specifications: Tighten the probe sleeve locknut to 39.3 N-m (350 in-lb) and the outer casing retaining screws to 29.5 N-m (260 in-lb) for mechanical security.
