Bently Nevada 330881-28-07-155-06-02 PROXPAC XL Proximity Transducer

Description

330881-28-07-155-06-02: This metric PROXPAC XL proximity transducer configuration features a 3300 XL 8 mm probe with multiple approvals (Option 28), a 70 mm standoff adapter (Option 07), 155 mm of probe penetration depth (Option 155), a specialized fittings kit (Option 06), and a 3/4-14 NPT mounting thread (Option 02).

In contrast to non-approved configurations or variants lacking a standoff adapter, this assembly integrates a robust, certified monitoring chain inside a durable Polyphenylene Sulfide (PPS) housing. The PROXPAC XL combines the probe and Proximitor sensor into a single integrated system, reducing external field wiring requirements by connecting directly to Bently Nevada monitors.

Features

• Option 28 integrates a 3300 XL 8 mm probe certified with Multiple Approvals for hazardous locations.
• Option 07 specifies a 70 mm metric standoff adapter to position the assembly clear of obstruction.
• Option 155 provides 155 mm of probe penetration length into the machine case.
• Option 06 supplies a fittings kit containing one 3/4-14 NPT fitting, one 3/4-14 NPT to 1 1/2-14 NPT stainless steel reducer, and two plugs.
• Option 02 establishes a 3/4-14 NPT mounting thread for the outer sleeve assembly.
• Glass and conductive fiber-reinforced Polyphenylene Sulfide (PPS) thermoplastic housing construction provides IP66 ingress protection and static charge dissipation.
• Direct-connect design integrates the Proximitor sensor directly into the housing cover, eliminating the need for an intermediate extension cable.

Applications

Typical applications include shaft vibration and axial position measurement on industrial rotating machinery, steam and gas turbines, centrifugal compressors, and large pumps where reduction of external wiring and junction boxes is required.

Installation Guidelines

Install the outer sleeve assembly into the machine case using thread sealant on the mounting thread (3/4-14 NPT). Adjust the probe gap within the housing using the probe sleeve locknut (torque to 39.3 N-m / 350 in-lb). Fasten the lid cover retaining nuts to 29.5 N-m (260 in-lb). Take standard industrial precautions to prevent external moisture from travelling through the conduit directly into the housing.

Compliance and Certifications

CE compliant. BASEEFA IP66 housing rating. Multiple Approvals package option includes certifications for hazardous locations (CSA, ATEX, IECEx where applicable).
