Bently Nevada 330881-28-10-148-03-02 PROXPAC XL Proximity Transducer

Description

Option 28 (3300 XL 8 mm probe with Multiple Approvals), Option 10 (100 mm standoff adapter), and Option 148 (148 mm probe penetration) specify this PROXPAC XL Proximity Transducer configuration — 330881-28-10-148-03-02. This integrated system combines a proximity probe and a Proximitor sensor into a single, self-contained metric assembly, completely eliminating the requirement for an external extension cable and separate Proximitor sensor housing. By routing the field wiring directly from the monitor to the terminal block inside the housing cover, installation footprint and connection complexity are substantially reduced.

This metric variant features an advanced molded polyphenylene sulfide (PPS) thermoplastic housing. The glass and conductive fiber reinforcement within the PPS material provides high mechanical strength and dissipates electrostatic charges. Rated for Type 4X and IP66 severe environments, the assembly includes one M20 conduit fitting with two plugs (Option 03) and a 3/4-14 NPT mounting thread (Option 02) to maintain housing integrity and protect the internal sensor from moisture and environmental contaminants.

Features

• Pre-installed 3300 XL 8 mm proximity probe and integrated Proximitor sensor in a single enclosure
• Option 28 integration provides built-in multiple hazardous area certifications
• Option 10 standoff adapter yields a fixed 100 mm metric spacing dimension
• Option 148 penetration depth specifies a 148 mm metric probe sleeve
• Option 03 conduit fitting kit provides one M20 fitting and two plugs
• Option 02 mounting interface utilizes a 3/4-14 NPT thread connection
• Conductive-fiber reinforced PPS thermoplastic housing rated for IP66 and Type 4X protection
• Elimination of extension cables reduces signal attenuation and connection failure points

Applications

• Radial vibration and axial position measurements on high-speed rotating shafts
• Metric machinery casings requiring external probe depth adjustments
• Severe-duty applications where separate probe, cable, and housing installations are impractical
• Petrochemical plants, gas pipelines, refineries, and power generation steam turbines

Installation Guidelines

• Housing Grounding: Ensure the housing is properly grounded via the pre-installed internal grounding liner and plate to prevent electrostatic discharge build-up.
• Environmental Sealing: Check that the neoprene sleeve O-ring is fully seated during installation. Seal any unused conduit ports with the supplied plugs.
• Torque Limits: Apply exactly 29.5 N-m (260 in-lb) to the retaining nut and 39.3 N-m (350 in-lb) to the probe sleeve locknut to secure the assembly without overstressing components.
• Moisture Prevention: Install conduit drains or loops to prevent moisture and condensation from tracking through the conduit line into the housing.
