Bently Nevada 330881-28-10-100-03-02 PROXPAC XL Proximity Transducer

Description

Option 28 (3300 XL 8 mm probe with Multiple Approvals) and Option 10 (100 mm standoff adapter) specify the configuration for this PROXPAC XL Proximity Transducer — 330881-28-10-100-03-02.

The 330881-28-10-100-03-02 integrates a 3300 XL 8 mm proximity probe and its matching Proximitor sensor directly into a single, compact polyphenylene sulfide (PPS) thermoplastic housing assembly. By combining the probe and Proximitor in one structure, this assembly removes the requirement for an external extension cable and separate Proximitor enclosure, which decreases cabling runs and simplifies field wiring connections directly to the monitoring system. This specific metric assembly features a 100 mm probe penetration length (Option 100), one M20 cable fitting with two plugs (Option 03), and 3/4-14 NPT mounting threads (Option 02) to accommodate the integrated standoff adapter. In contrast to unapproved variants, this system is certified with multiple hazardous area approvals, enabling deployment in Class I, Division 1 and 2 or Zone 0, 1, and 2 environments.

Features

• Option 28 integrates a built-in 3300 XL 8 mm proximity probe pre-configured with multiple international hazardous area certifications.
• Option 10 specifies a 100 mm metric standoff adapter to space the housing away from the machine case.
• Option 100 designates a 100 mm probe penetration sleeve length for casing access and depth positioning.
• Option 03 includes an installation kit with one metric M20 conduit fitting and two blanking plugs.
• Option 02 provides 3/4-14 NPT mounting threads to support secure physical attachment of the standoff adapter.
• Polyphenylene sulfide (PPS) thermoplastic housing with glass and conductive fibers offers Type 4X and IP66 environmental protection and static dissipation.
• Integrated Proximitor sensor design facilitates direct-to-monitor field wiring, eliminating intermediate extension cables.

Applications

This integrated transducer system is optimized for machinery protection environments where cabling space is limited or where traditional separate housings are difficult to install. Typical industrial applications include:

• Shaft radial vibration and axial position measurement on high-speed rotating machinery.
• Turbine, compressor, generator, and gearbox monitoring systems.
• Severe environmental applications requiring robust non-corrosive chemical protection and static dissipation.
• Hazardous areas requiring intrinsically safe or non-incendive field installations.

Installation Guidelines

To establish safe and accurate measurement parameters, adhere to the following setup practices:

• Mount the housing assembly through the machine case using the 3/4-14 NPT threads (Option 02) specified for standoff adapter configurations.
• Ensure the internal 3300 XL 8 mm probe is set to the nominal gap of 1.27 mm (50 mils) from the target surface during installation.
• Use 3-conductor shielded triaxial field wiring (0.2 to 1.5 mm2 or 16 to 24 AWG) with a tinned copper drain wire for signal connection back to the monitor.
• Protect against water ingress by verifying that all conduit fittings (such as the M20 fitting supplied under Option 03) and blanking plugs are tight and properly sealed.
