Bently Nevada 330881-28-00-150-03-02 PROXPAC XL Proximity Transducer

Description

330881-28-00-150-03-02: PROXPAC XL Proximity Transducer, Metric assembly featuring an integrated 3300 XL 8 mm probe with Multiple Approvals (Option 28), no standoff adapter (Option 00), 150 mm sleeve penetration depth (Option 150), one M20 conduit fitting with two plugs (Option 03), and a 3/4-14 NPT mounting thread (Option 02).

This integrated design simplifies machinery installation by mounting the 3300 XL Proximitor sensor directly into the housing cover, eliminating the need for separate extension cables or remote Proximitor enclosures. The housing is molded from glass-reinforced polyphenylene sulfide (PPS) with conductive fibers to dissipate electrostatic charges and withstand severe, corrosive environments. Signal transmission goes directly from the field wiring to the rack monitor, reducing the number of connections and enhancing signal integrity.

Features

• Option 28 integrates a 3300 XL 8 mm proximity probe with multiple international hazardous area certifications.
• Option 00 configures the assembly without a standoff adapter, enabling a direct mount on the machinery casing.
• Option 150 provides a 150 mm stainless steel probe sleeve for medium-depth penetration into machine cases.
• Option 03 supplies one M20 cable entry fitting and two blanking plugs for standard metric field wiring connection.
• Option 02 designates a 3/4-14 NPT mounting thread for securing the outer sleeve assembly.
• Polyphenylene sulfide (PPS) thermoplastic housing is rated IP66 and NEMA Type 4X for high resistance to steam and hot water.
• Eliminates intermediate extension cables between the probe tip and Proximitor sensor to minimize signal attenuation.

Applications

• Shaft vibration and axial position monitoring in heavy industrial rotating machinery.
• Monitoring installations with severe space or cabling constraints where remote Proximitor enclosures are impractical.
• Petrochemical, oil and gas, and power generation machinery protection programs.
• Deployment in hazardous areas requiring certified intrinsically safe (ia) or non-sparking (nA/ec) transducer designs.

Installation Guidelines

To ensure proper mechanical and electrical sealing, mount the outer sleeve with the E: Mounting Thread (Option 02) which designates a 3/4-14 NPT thread. Keep the following installation practices in mind:

• Tighten the retaining nut to the recommended torque of 29.5 N-m (260 in-lb).
• Ensure the probe sleeve locknut is tightened to 39.3 N-m (350 in-lb) to prevent rotational slip or fluid leaks.
• Avoid installing the unit in areas of continuous fluid submersion; while IP66-rated, the housing is not designed for underwater deployment.
• Verify that the field wiring enters through the supplied M20 fitting (Option 03) and use proper conduit seals to prevent moisture ingress into the thermoplastic housing.
