Bently Nevada 330881-BR-07-155-06-02 PROXPAC XL Proximity Transducer

Description

330881-BR-07-155-06-02: This metric PROXPAC XL Proximity Transducer features a 3300 XL 8 mm proximity probe with Brazil INMETRO hazardous area approvals (Option BR), an integrated 70 mm standoff adapter (Option 07), and a 155 mm probe penetration sleeve length (Option 155). This configuration is supplied with one 3/4-14 NPT fitting, one 3/4-14 NPT to 1 1/2-14 NPT stainless steel reducer, and two conduit plugs (Option 06) and utilizes a 3/4-14 NPT mounting thread (Option 02).

The integrated design combines both the 3300 XL 8 mm probe and its matching Proximitor sensor into a single, self-contained polyphenylene sulfide (PPS) housing. This approach eliminates the separate extension cable and external Proximitor enclosure, allowing field wiring to connect directly from the monitoring system to the terminal block inside the transducer cover. The glass- and conductive-fiber-reinforced PPS housing delivers IP66 and Type 4X environmental protection, securing the internal electronics against severe industrial conditions, moisture ingress, and electrostatic buildup.

Features

• Option BR includes a 3300 XL 8 mm probe certified with Brazil INMETRO approvals for intrinsic safety and non-sparking hazardous area protection.
• Option 07 provides a 70 mm standoff adapter length to elevate the enclosure above the machine casing.
• Option 155 designates a 155 mm probe penetration sleeve length to match target depth specifications.
• Option 06 includes a heavy-duty 3/4-14 NPT conduit fitting, a 1 1/2-14 NPT stainless steel reducer, and dual blanking plugs.
• Option 02 provides a 3/4-14 NPT mounting thread to ensure a robust mechanical connection.
• Self-contained design eliminates external extension cables and remote Proximitor enclosures to reduce wiring errors and simplify installation.
• Conductive PPS thermoplastic housing dissipates electrostatic charges and resists ultraviolet radiation and aggressive chemicals.

Applications

• Shaft vibration and axial position measurement on high-speed rotating machinery.
• Machinery protection monitoring where a simplified transducer footprint and direct terminal field wiring are preferred.
• Severe-duty applications requiring IP66 and Type 4X corrosion-resistant housing protection.
• Hazardous locations requiring INMETRO-certified intrinsic safety or non-sparking configurations.

Installation Guidelines

Mount the housing securely using the 3/4-14 NPT thread. Ensure the standoff adapter is aligned correctly with the machinery sleeve port. Tighten the probe sleeve locknut to a torque of 39.3 N-m (350 in-lb) and the retaining nut to 29.5 N-m (260 in-lb) to maintain a secure physical seal. Field cables must be routed through the conduit fittings provided by Option 06; tighten all compression fittings and plugs to maintain the IP66 and Type 4X rating of the PPS enclosure. Ensure local grounding guidelines are followed using the integrated internal ground liner assembly.
