        Applications for the 24.4 in penetration
        • Deep machine cases: positions the probe through thick bearing housings, covers or external mounting structures
        • Radial monitoring: supports shaft vibration and radial-position measurement on turbines, compressors, pumps, motors and generators
        • Remote adjustment: the threaded sleeve permits probe position adjustment from outside the machine case
        • Protected routing: the dome housing and conduit ports protect the probe connector and cable transition
        • Long reach: useful where the measurement target is significantly below the external housing mounting surface
        • Sleeve stability: the 24.4 in penetration requires support near the probe to control resonance

        Confirm target location, machine-wall thickness, required probe gap and available support points from the installation drawing before ordering.

        Probe, sleeve and mounting compatibility
        • Probe family: supplied for a 3300 XL 8 mm reverse-mount probe with a 1.0 m lead
        • Electrical system: match the probe approval and electrical-length configuration to the extension cable and Proximitor Sensor
        • Machine interface: verify a 3/4-14 NPT mounting point and sufficient external clearance for the housing dome
        • Sleeve dimension: confirm that 24.4 in reaches the target while allowing the required adjustment and probe gap
        • Support requirement: add a sleeve support or oil seal near the probe because the penetration exceeds 12 in
        • Fitting scope: option 04 supplies only an NPT plug; conduit fittings and cable seals must be selected separately

        Provide the existing housing, probe, extension cable and Proximitor part numbers for a complete compatibility review.

        Hazardous-area and installation checks
        • Housing material: aluminum body with 304 stainless steel sleeve
        • Probe approvals: option 28 provides selectable hazardous-area approvals for the 3300 XL 8 mm probe
        • Enclosure distinction: the standard 21000 housing is not the CSA explosion-proof CA21000 enclosure
        • Conduit entry: option 04 includes one 3/4-14 NPT plug but no explosion-proof fitting
        • Installation drawing: verify the probe approval, wiring method, end-user country and required certificate set
        • Mechanical support: secure the long sleeve near the probe and check resonance, oil sealing and cable clearance
        • Replacement review: Bently Nevada recommends newer 31000/32000 housings where explosion-proof construction is not required

        Do not infer housing certification from the probe option. Confirm the complete assembly nameplate and jurisdictional requirements before installation.

        Description

        The Bently Nevada 21000-28-10-00-244-04-02 is an externally mounted aluminum proximity probe housing assembly with a 304 stainless steel sleeve. It includes a 3300 XL 8 mm reverse-mount probe with selectable hazardous-area approvals and a 1.0 m (39 in) probe cable.

        This configuration has no standoff adapter, a 24.4 in probe-penetration dimension, one 3/4-14 NPT plug and a 3/4-14 NPT machine-mounting thread. Because the combined penetration exceeds 12 in, the official datasheet requires sleeve support near the probe to prevent resonance. The standard 21000 housing is not automatically CSA explosion-proof; that rating applies to the separately ordered CA21000 configuration.

        Technical notes
        The Bently Nevada 21000-28-10-00-244-04-02 combines a 1.0 m approved 3300 XL 8 mm probe with a 24.4 in long sleeve arrangement and 3/4-14 NPT mounting. Provide sleeve support for the long penetration and do not treat the standard 21000 housing as a CA21000 explosion-proof enclosure.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What is the Bently Nevada 21000-28-10-00-244-04-02?
        It is an externally mounted aluminum proximity probe housing assembly with a 304 stainless steel sleeve, a 1.0 m 3300 XL 8 mm probe and a 24.4 in penetration dimension.
        Which probe is supplied with this housing configuration?
        Option 28 supplies a 3300 XL 8 mm reverse-mount probe with selectable hazardous-area approvals and a 1.0 m cable.
        Does this model include a standoff adapter?
        No. Option 00 specifies no standoff adapter; the 24.4 in value is the probe-penetration dimension.
        Is sleeve support required for the 24.4 in penetration?
        Yes. Bently Nevada requires support near the probe when the combined standoff and penetration exceed 12 in to prevent sleeve resonance.
        Which fitting is included with option 04?
        Option 04 includes one 3/4-14 NPT plug only. It does not include an explosion-proof conduit fitting.
        What mounting thread does option 02 specify?
        Option 02 specifies a 3/4-14 NPT machine-mounting thread.
        Is the standard 21000 housing CSA explosion-proof?
        No. The approved probe option does not make the standard 21000 enclosure explosion-proof. CSA explosion-proof certification applies to the separately ordered CA21000 configuration with permitted options.
        What information should be provided for a quotation?
        Provide the complete part number, quantity, machine-case dimensions, required probe approvals, end-user country, sleeve-support arrangement, certificates and delivery destination.
