Bently Nevada 330881-28-00-070-03-02 PROXPAC XL Proximity Transducer

Description

Option 28 specifies a 3300 XL 8 mm probe with multiple approvals, while Option 070 sets a 70 mm probe penetration length for this metric 330881-28-00-070-03-02 configuration of the Bently Nevada PROXPAC XL Proximity Transducer.

The PROXPAC XL assembly integrates a 3300 XL 8 mm proximity probe and a 3300 XL Proximitor sensor into a single, self-contained glass-reinforced polyphenylene sulfide (PPS) housing. This configuration eliminates the need for an extension cable between the probe and Proximitor sensor, as well as the requirement for a separate Proximitor housing. Field wiring connects directly from the monitoring system to the assembly. A Type 4X and IP66 rating provides protection in wet or harsh environments.

Features

• Option 28 integrated probe and Proximitor configuration includes international multiple approvals.
• Option 070 establishes a 70 mm probe penetration length inside the protective sleeve.
• Option 03 provides one metric M20 conduit fitting and two blanking plugs.
• Option 02 specifies a 3/4-14 NPT mounting thread.
• Glass-reinforced polyphenylene sulfide (PPS) thermoplastic housing incorporates conductive fibers for electrostatic charge dissipation.
• Direct connection from field wiring to the internal Proximitor sensor eliminates separate extension cabling.
• IP66 and Type 4X environmental ratings shield internal components from hose-directed water and dust.

Applications

• Shaft vibration monitoring on industrial rotating machinery.
• Axial position and radial displacement tracking.
• Fluid-film bearing machine cases.
• Steam turbines, gas turbines, compressors, and gearboxes.
• Severe industrial environments requiring physical protection of transducer components.

Installation Guidelines

Correct installation is essential for proper sensor function and protection:

• Ensure the housing is properly sealed with the provided plugs and fittings to prevent moisture ingress.
• Use the internal grounding liner and plate to ensure correct electrical grounding.
• When routing field wiring, prevent moisture from traveling through the conduit into the housing.
• Adhere to specified torque values: 29.5 N-m for the retaining nut and 39.3 N-m for the probe sleeve locknut.
