Applications And Installation Checks
Confirmed Compatibility Conditions
Treat 330800 as a legacy English PROXPAC configuration. Match the complete code, 4.5 in standoff, 2.0 in penetration, reducer fitting kit, 3/4-14 NPT thread, installed probe, Proximitor sensor, field wiring and monitor input. Do not substitute the current 330880 base number without an engineering review.
Approval And Documentation Check
Option 28 identifies an 8 mm probe with Multiple Approvals in the manufacturer ordering structure. Confirm the exact legacy assembly certificate and installed-area method before reuse or replacement.
Lifecycle And Replacement Guidance
The reviewed manufacturer material does not provide an exact discontinuation date or confirm a universal drop-in replacement for 330800-28-45-020-03-02. Keep the complete ordering code and verify all mechanical, electrical, system-length, approval and installation conditions before substitution.
Frequently Asked Questions
What does the complete 330800-28-45-020-03-02 code specify?
It identifies the legacy English PROXPAC assembly, approved 8 mm probe option 28, 4.5 in standoff, 2.0 in penetration, reducer-equipped fittings and a 3/4-14 NPT mounting thread.
Does 330800-28-45-020-03-02 use a separate extension cable?
The PROXPAC design places the Proximitor sensor in the housing cover and eliminates the probe-to-Proximitor extension cable.
Can current model 330880 directly replace 330800-28-45-020-03-02?
The current datasheet uses 330880 for English PROXPAC XL assemblies, but the reviewed documents do not state that every 330800 code is a direct drop-in replacement. Confirm dimensions, electronics, lid, field wiring and approvals.
Which fittings are supplied with 330800-28-45-020-03-02?
Option 03 specifies one 3/4-14 NPT fitting, one 3/4-14 to 1/2-14 NPT stainless-steel reducer and two plugs.
Is a discontinuation date published for 330800-28-45-020-03-02?
The reviewed manufacturer documents show the legacy and current ordering structures but do not state an exact discontinuation date for this complete 330800 configuration.
Model Identification
Use the complete number 330800-28-45-020-03-02. Hyphen placement and zero padding are significant in Bently Nevada ordering codes. Similar-looking suffixes identify different dimensions, cable constructions, approvals or fittings, so quotations and replacements must be checked against the full label.
