Parameter Analysis

Configuration of the 21000-34-05-30-028-04-02 is carried entirely in its part number, which makes the full string the reference point for spare parts planning and system design. The probe Option specifies with Connector: 34 =3300 XL 8 mm probe with connector protector, selectable hazardous area approvals. The mounting thread Option specifies -02 – 3/4-14 NPT (Must be ordered if Standoff Adapter Length Option is not -00). The l a probe sleeve of Option specifies al length.

The housing assembly seals the probe penetration against wash-down and dust while allowing standard probe maintenance, combining mechanical protection with the electrical performance of the enclosed probe.

Application Scenarios

Installations on rotating machinery that demand sealed probe penetrations rely on this housing to guard against dust, hose-directed water, and mechanical contact while keeping the probe serviceable.

Installation Guide

Confirm every option digit against the machine drawing, mount the housing through its threaded connection, tighten the retaining nut to the documented torque, and keep the sleeve O-rings seated to preserve the environmental seal. Set the probe gap after assembly and verify before start-up.

Compatibility

This component belongs to the 3300 XL 8 mm proximity system and is engineered to work with the associated probes, extension cables, Proximitors, and monitoring hardware of the same system. Bently Nevada components sharing the same part number are fully interchangeable, so a stocked spare can be fitted without re-engineering the measurement loop. TenBN can supply the complete chain under consistent part numbers.

Maintenance Advice

Inspect the housing cover, screws, and O-rings at each maintenance opportunity, and confirm the retaining nut torque has not relaxed in service.

Procurement Advice

This unit is supplied new & original in factory packing with 12 months factory warranty. Confirm the complete part number against your machine’s bill of materials before ordering, since each option digit changes the mechanical or electrical fit. TenBN stocks genuine Bently Nevada components and provides the official service documentation for this model.

Frequently Asked Questions

Can this spare be interchanged with existing components?

Bently Nevada components sharing the same part number are fully interchangeable, so this spare can replace an existing unit without recalibrating the loop when the complete part number matches.

How do I confirm the right part number?

Check every option digit against the machine bill of materials, then contact [email protected] with the full string; the TenBN team will confirm fit, stock, and documentation.
