LEGACY 330801 IDENTITY · 3300 XL 8 MM SYSTEM · METRIC HOUSING
Bently Nevada 330801-28-20-050-03-02 Legacy PROXPAC XL Metric Proximity Transducer Assembly
A legacy metric PROXPAC configuration whose full six-field order string controls the installed probe, sleeve and housing fit.
Overview
330801-28-20-050-03-02 identifies a legacy metric PROXPAC XL assembly. The product combines a 3300 XL 8 mm probe and Proximitor Sensor inside one externally accessible housing, so a separate extension cable and remote Proximitor enclosure are not required.
The submitted order string retains the multiple-approval probe option, a 200 mm standoff entry, 50 mm probe penetration, the armored-cable fitting arrangement and 3/4-14 NPT mounting thread. These fields belong together as one mechanical and electrical identity.
Specifications
Features
Self-contained measurement chain
The probe and Proximitor Sensor share one housing, reducing remote interconnect hardware.
External service access
Probe gap adjustment and replacement can be performed from outside the machine case.
Severe-environment housing
Glass-reinforced conductive PPS and stainless-steel hardware provide corrosion resistance and IP66 protection.
Complete mechanical coding
Standoff, penetration, fittings and mounting thread are carried in the same catalog string.
About IndustryParts
https://www.industryparts.com/Exact identity before quotation
IndustryParts prepares 330801-28-20-050-03-02 enquiries around the complete manufacturer label, requested quantity and destination. For controlled replacements, include the host-system record, field photographs and configuration evidence that apply to this exact execution.
Applications
Radial shaft vibration
Mounting an 8 mm eddy-current probe through a machine case for relative vibration measurement.
Position monitoring
Using the published 2 mm linear range where target geometry and calibration are suitable.
Legacy PROXPAC service
Replacing an installed 330801 assembly only after its sleeve dimensions and approval record are preserved.
Lifecycle
Capture
Photograph the full label and measure the standoff, penetration and machine-case thread before removal.
Match
Compare every suffix field with the proposed replacement and retain the original barrier or non-barrier circuit record.
Gap and prove
Set the approved probe gap, verify static voltage and dynamic response, then complete the machinery-monitoring acceptance test.
FAQ
What must accompany a 330801-28-20-050-03-02 enquiry?
Provide the complete label, machine location, target material, gap voltage, barrier details and measured housing dimensions.
Can a 330881 assembly replace 330801-28-20-050-03-02 by family name alone?
No. The current metric family must be configured to reproduce the legacy standoff, penetration, fittings, thread and approval boundary.
Why is the 20 field important on 330801-28-20-050-03-02?
It carries the legacy metric standoff dimension, which changes sleeve geometry and machine-case fit.
How should moisture risk be handled around 330801-28-20-050-03-02?
Seal conduit entries and prevent moisture from travelling through conduit; the housing is non-submersible even though it is Type 4X/IP66.
What closes a 330801-28-20-050-03-02 replacement record?
Record the exact delivered code, final gap voltage, waveform response, alarm behavior and the approved installation inspection.
