Bently Nevada 330881-28-06-105-00-02 PROXPAC XL Proximity Transducer

Description

Option 28 (3300 XL 8 mm probe with Multiple Approvals) and Option 06 (60 mm standoff adapter length) specify this metric PROXPAC XL Proximity Transducer configuration — 330881-28-06-105-00-02. The system integrates a 3300 XL 8 mm proximity probe and a 3300 XL Proximitor sensor into a single Polyphenylene Sulfide (PPS) housing. This integrated design eliminates the need for an extension cable between the probe and Proximitor, significantly simplifying field installation on rotating machinery.

Unlike standard configurations that utilize separate components, the 330881-28-06-105-00-02 features a 105 mm probe penetration depth (Option 105) and a 3/4-14 NPT mounting thread (Option 02). The robust glass-reinforced thermoplastic housing offers a Type 4X and IP66 environmental rating, which is highly effective at resisting harsh environments and dispersing electrostatic charges. Field wiring connects directly inside the terminal junction of the assembly, removing the need for a separate Proximitor junction box.

Features

• Option 28 integrated design: Pairs a 3300 XL 8 mm proximity probe with a built-in Proximitor sensor inside a single enclosure.
• Polyphenylene Sulfide (PPS) housing: Constructed with glass-reinforced thermoplastic and conductive fibers to dissipate electrostatic charges and resist chemical corrosion.
• Option 06 standoff adapter: Incorporates a 60 mm standoff adapter to accommodate specific machinery mounting requirements.
• Option 105 penetration length: Standardizes on a 105 mm probe penetration depth for accurate shaft vibration and position monitoring.
• Option 02 mounting thread: Utilizes a standard 3/4-14 NPT thread, required for secure standoff mounting.
• Option 00 fittings: Standard package includes two plugs and two washers with no external conduit fittings.
• Type 4X and IP66 rating: Certified housing provides robust protection against ingress of dust and water.

Applications

Typical applications include rotating machinery vibration and axial position measurements where separate Proximitor mounting is impractical. The chemically resistant PPS housing enclosure makes this assembly suitable for severe industrial environments, such as steam turbines, gas turbines, compressors, and high-speed pumps.

Installation Guidelines

• Ensure the probe sleeve locknut is torqued to 39.3 N-m (350 in-lb).
• Ensure the housing retaining nut is torqued to 29.5 N-m (260 in-lb).
• Take precautions to prevent moisture from traveling through the conduit into the housing.
• Exposing the probe to temperatures below -34 degC (-29 degF) may cause premature failure of the pressure seal.
• Ground the system properly using the integrated stainless steel grounding liner.

Compliance and Certifications

• CE Mark: Yes
• Ingress Protection: IP66 / Type 4X
• Hazardous Area Approvals: Multiple Approvals (Option 28 integrates certified probe and Proximitor sensor; certified by BASEEFA, CSA)
