21000-28-05-00-056-04-02 ordering code
  • 21000: aluminum proximity probe housing assembly
  • 28: 3300 XL 8 mm probe with selectable hazardous-area approvals
  • 05: 0.5 m (20 in) probe cable
  • 00: no standoff adapter
  • 056: 5.6 in probe penetration
  • 04: one 3/4-14 NPT plug only
  • 02: 3/4-14 NPT mounting thread
Typical measurement applications
  • Radial vibration and shaft-position measurement on fluid-film bearing machines
  • Keyphasor, phase-reference and speed measurements with a compatible 3300 XL 8 mm system
  • External probe mounting on turbines, compressors, pumps, motors and generators
  • Machine-casing installations requiring a protected reverse-mount proximity probe
  • Industrial or classified-area installations after approval and nameplate verification

The housing supports the probe mechanically; the complete transducer loop must still use electrically compatible probe, extension cable and Proximitor Sensor components.

Installation and setup checks
  • Confirm that the machine-casing mounting point is prepared for a 3/4-14 NPT thread
  • Verify that the specified 5.6 in penetration provides the required probe position and adjustment range
  • Install the housing directly because option 00 does not include a standoff adapter
  • Route the 0.5 m probe cable through the conduit port without exceeding bend or pull limits
  • Use the supplied NPT plug and approved sealing method required by the installation
  • Set the probe gap and verify the complete 3300 XL 8 mm transducer loop before service

Follow the official Bently Nevada installation documentation and local hazardous-area wiring requirements.

Environmental and approval data
  • Housing body: aluminum
  • Probe sleeve: 304 stainless steel
  • 3300 XL 8 mm probe operating and storage range: -51°C to +177°C (-60°F to +351°F)
  • Compliance: RoHS Directive 2011/65/EU
  • Probe option 28: selectable hazardous-area approvals
  • Approval check: verify end-user country, delivered nameplate, certificate and approved wiring method

Explosion-proof and hazardous-area acceptance is configuration- and region-specific. Do not rely on the model family alone when approving an installation.

Description

The Bently Nevada 21000-28-05-00-056-04-02 is an aluminum external-mount proximity probe housing assembly configured with a 3300 XL 8 mm probe that supports selectable hazardous-area approvals. Its 0.5 m probe cable, no-standoff arrangement and 5.6 in penetration suit fixed machine-casing installations.

The assembly uses one 3/4-14 NPT plug and a 3/4-14 NPT mounting thread. The housing protects the reverse-mount probe and supports cable routing through threaded conduit ports for machinery vibration, radial-position and phase-reference measurements.
