        Overview Manuals Probe Geometry 7200 System Chain Signal Setup Application
        • The standard-mount 7200 Series 8 mm probe supports non-contact shaft-relative measurement
        • The 3/8-24 UNF body and 4.0 inch case suit the documented legacy mounting arrangement
        • The 1.0 m unarmored lead uses a miniature coaxial connector and requires protected routing

        21504-000-040-10-02 is a Bently Nevada 7200 Series 8 mm standard-mount proximity probe for shaft-relative measurement.

        Its 3/8-24 UNF body, 4.0 inch case, 1.0 m unarmored lead, and miniature coaxial connector must match the installed mechanical and electrical chain.

        Confirm target clearance, bracket position, matched 7200 extension cable and Proximitor, static gap, and monitor scaling before return to service.

        • The 3/8-24 UNF body adjusts through the existing machine bracket.
        • The 4.0 inch case provides the insertion reach specified by this configuration.
        • The 1.0 m unarmored lead requires protection from abrasion and strain.
        • The 1.0 m unarmored probe lead forms the first section of the calibrated electrical path.
        • Use the compatible 7200 extension cable to complete the required system length.
        • Keep the miniature coaxial connector clean, dry and fully seated to prevent intermittent output.
        • Adjust the probe depth until the conditioned static output lies within the linear measurement region.
        • Verify the target material, total electrical length and electronics type before recalibrating the channel.
        • During low-speed testing, distinguish target runout from actual shaft motion.
        • Measure radial shaft movement relative to the bearing housing.
        • Monitor axial thrust displacement using a suitable collar or shaft target.
        • Provide proximity measurement data for condition trending, alarms and machinery diagnostics.
        Description
        The 21504-000-040-10-02 is a standard-mount 7200 Series 8 mm proximity probe for non-contact shaft-relative measurement. With the matching 7200 extension cable and Proximitor electronics, target movement becomes a static position or dynamic vibration signal for the monitoring channel.

        This 21504-000-040-10-02 configuration is intended for legacy brackets that require a 3/8-24 body and a 4.0 inch insertion case. Its 1.0 m unarmored lead and miniature coaxial termination make cable protection and connector condition part of the measurement installation, not merely mechanical accessories.

        The 21504-000-040-10-02 supports radial-vibration and axial-position points on turbines, compressors, pumps and generators that retain a 7200 architecture. Keeping the original probe geometry, total electrical length and target material aligned allows the installed electronics to preserve the expected scale and usable gap region.

        Technical notes
        Bently Nevada 21504-000-040-10-02 is an unarmored 8 mm 7200 probe with a 3/8-24 thread, 4.0 in case, 1 m lead, and coaxial connector. Match the extension cable and Proximitor as a documented 7200 system rather than substituting 3300 XL components.

        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
        Can Bently Nevada 21504-000-040-10-02 operate as a complete measurement channel by itself?
        No. It is the probe portion of a 7200 system and must be used with the correct extension cable, Proximitor, power supply, monitor input, and total electrical length.
        Will Bently Nevada 21504-000-040-10-02 fit a location previously using an armored 21505 probe?
        Do not assume so. The 21504 has no stainless-steel lead armor, while the 21505 family is armored; mechanical protection, cable routing, and the approved probe identity must be reviewed before substitution.
        How does the 4.0 in case of Bently Nevada 21504-000-040-10-02 affect installation?
        The full case must reach the target while leaving wrench, jam-nut, cable, and connector clearance. Compare the 0.0 in unthreaded length and 4.0 in overall case with the machine drawing before ordering.
        Can Bently Nevada 21504-000-040-10-02 be mixed with 3300 XL probe-system components?
        The archived catalog states that 7200 systems work with 3300 and 9000 monitors, but that does not make the probe, extension cable, and Proximitor interchangeable with 3300 XL components. Keep the matched 7200 transducer chain.
        What should be checked if Bently Nevada 21504-000-040-10-02 produces an incorrect gap voltage after installation?
        Check the 1 m lead, coaxial connector, extension-cable and Proximitor match, target material, mounting rigidity, and actual probe-to-target gap before changing monitor settings.
        Is Bently Nevada 21504-000-040-10-02 suitable for a non-steel or differently alloyed target?
        Published performance was established with an AISI 4140 steel target. A different conductive target can change scale factor and linearity and requires application review or calibration.
        Can hazardous-area approval be inferred for Bently Nevada 21504-000-040-10-02 from the 7200 catalog?
        No exact approval suffix is encoded in this probe order number. Confirm the Proximitor approval, barrier arrangement, installation drawing, and site classification as a complete system before use.
