        Overview Manuals Sensor Fit Signal Chain Installation Fit Applications

        Features:

        • Matched chain: The PR6424 probe connects to a CON021 converter, distinguishing this offering from a probe-only spare.
        • Ordered build: The 010-010 code identifies the probe mounting, armor, cable length and connector choices that affect physical fit.
        • Signal role: Non-contact shaft motion becomes a voltage signal for a correctly configured machinery-monitoring channel.
        Unlike a probe-only spare, this offered pair includes signal conditioning; the receiving channel and target material still govern how its output is interpreted.

        Emerson's PR6424 order matrix helps identify mechanical and cable choices without treating a nearby order code as the same configured item.

        The installed converter label and shaft target matter alongside the probe code because Emerson adjusts the complete measurement chain.

        Apter Power can help compare the installed PR6424/010-010-CN CON021 chain and provide an exact-part quotation with technical documentation.
        Emerson PR6424/010-010-CN CON021 Eddy Current Sensor and CON021 Converter Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Mounting thread: The M18 × 1.5 sleeve must match the installed probe bracket rather than a visually similar threaded opening.
        • Probe reach: Emerson defines Cx as 40 mm and overall length C as Cx plus 12.5 mm, so clearance depends on the full assembly.
        • Cable protection: The ordered armor helps protect the routed cable; the cable path and bend space remain part of the fit check.
        • Termination: The ordered 5 m cable ends in LEMO, so a different converter inlet or cable route changes the needed spare.
        • Target calibration: Emerson uses 42CrMo4 as its reference material; a different shaft alloy can change the chain response and may need adjustment.
        • Matched components: The probe and CON021 form an adjusted measuring chain, so exchanging one component is not automatically an equivalent calibration.
        • Receiver interface: The CON021 delivers a negative-voltage output, which must match the receiving monitoring channel rather than a current-loop input.
        • Output setting: The converter bridge selects the voltage range, and the matching supply limits depend on that setting.
        • Probe position: The non-contact measurement depends on a suitable working gap from the shaft target, not merely on a matching thread.
        • Nearby channels: Emerson documents mutual influence between adjacent probes and gives PR6424 spacing guidance for the installation layout.
        • Target geometry: The shaft and measuring surface must suit the PR6424 probe geometry for the published measurement behavior to apply.
        • Converter location: Its LEMO probe inlet and power/output terminals should be checked against the installed cabinet wiring and cable reach.
        • Radial vibration: In a configured turbine or compressor channel, the probe can follow shaft movement without touching the rotor.
        • Axial position: A suitable mounting position lets the measuring chain track shaft movement relevant to thrust monitoring.
        • Eccentricity: Low-speed shaft movement can be interpreted through an appropriately configured monitoring channel.
        • Speed reference: Emerson includes speed/key among PR6424 applications when the target feature and receiving equipment are selected for that task.
        Description
        In a turbine or compressor shaft-monitoring channel, PR6424/010-010-CN CON021 combines a PR6424 eddy-current probe with a CON021 converter. The measuring chain turns probe-to-shaft distance changes into a voltage signal for vibration, position and eccentricity monitoring in the configured machinery system.

        The probe ordered as part of PR6424/010-010-CN CON021 has an M18 × 1.5 sleeve, armored cable, adapter plug and a 5 m cable ending in LEMO. Emerson defines the 40 mm value in this code as Cx, not overall probe length; the stated C=Cx+12.5 mm relationship makes mount clearance and cable routing important when selecting a spare.

        For service replacement, Apter Power can compare PR6424/010-010-CN CON021 with the installed probe, converter label and shaft target before quotation. Emerson describes the sensor and converter as an adjusted measurement chain, so matching the physical configuration alone does not establish the channel calibration.

        Technical notes
        Emerson adjusts the PR6424 sensor and CON021 converter as a measurement chain against the target material. Replacing either item without checking the installed calibration can change the indicated gap or vibration value. Apter Power can review the existing labels, probe order code, cable termination and target details when sourcing a matching spare.

        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
        Will PR6424/010-010-CN CON021 fit my existing probe mounting and cable route?
        The ordered probe uses an M18 × 1.5 sleeve, armor, a 5 m cable and a LEMO end. The 40 mm order-code value is Cx rather than overall probe length, so Apter Power can compare your bracket clearance and route before quoting a replacement.
        Can I replace only the converter from PR6424/010-010-CN CON021?
        A converter-only replacement needs a measurement-chain check. Emerson adjusts the converter with the sensor and target material; Apter Power can help compare the installed converter label and calibration details before sourcing the spare.
        Will PR6424/010-010-CN CON021 give the same reading on a different shaft alloy?
        Not automatically. Emerson specifies 42CrMo4 as the reference target and allows adjustment for other conductive materials, which can change the measurement response. Share the actual shaft material so Apter Power can help assess the matching chain.
        Can PR6424/010-010-CN CON021 connect directly to a 4–20 mA input?
        The CON021 provides a negative-voltage output, not a 4–20 mA current loop. Apter Power can help compare the receiving monitor input and output-range setting before you select an interface or replacement channel.
        What matters when PR6424/010-010-CN CON021 is mounted near another probe?
        Adjacent eddy-current channels can influence one another. Emerson provides PR6424-specific spacing guidance and a converter detuning option; Apter Power can help review probe placement and the installed measurement-chain arrangement.
        What should I check when the output of PR6424/010-010-CN CON021 stays near a limit?
        A limit reading alone does not identify a failed probe. Emerson distinguishes converter output patterns during fault finding; checking the measured output, cable connection and probe gap helps narrow the issue before ordering a spare.
