      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • The 21000 assembly places a proximity probe through the machine case while housing its external cable junction.
      Assembly: 21000 aluminum housing with 8 mm protected probe option
      Installed geometry: 7.0 in penetration; no standoff adapter
      Fitting interface: 3/4-14 NPT mounting; single 3/4-14 NPT plug
      The 21000 base design uses an aluminum dome cover, threaded conduit ports and probe sleeve to externally mount a proximity probe. Group 33 selects the 3300 XL 8 mm probe with connector protector; group 10 selects a 1.0 m probe cable. Confirm the offered assembly contents against the order record.

      Group 00 omits a standoff adapter, while 070 specifies 7.0 in nominal probe penetration. The source calls for sleeve support when C plus D exceeds 12 in; for this configuration compare actual installed support, side-view clearance and the shaft target before setting the gap.

      Group 04 supplies a single 3/4-14 NPT plug and group 02 selects 3/4-14 NPT mounting thread. Do not infer a hazardous-area enclosure rating from a fitting name: the datasheet distinguishes the CA variants and actual approval configuration.
      Controller platform reference: Bently Nevada 21000 probe housing and 3300 XL 8 mm chain. Check probe, sleeve and sensor separately.
      For 21000-33-10-00-070-04-02, the official Bently Nevada family datasheet excerpt provides applicable reference specifications. The Apter Power engineering guide covers installation, commissioning, fault isolation and handover.
      Use the applicable Bently Nevada documentation and site-approved machinery procedure when installing 21000-33-10-00-070-04-02.
      Mechanical role: 21000-33-10-00-070-04-02 carries the protected 8 mm probe through an external housing and sleeve.

      Electrical role: The selected probe still requires a compatible extension cable and 8 mm Proximitor Sensor for a calibrated chain.
      Prepare Bently Nevada 21000-33-10-00-070-04-02 using the applicable installation instructions and site isolation procedure.
      Match six groups

      Compare every group of 21000-33-10-00-070-04-02 with the installed housing and source drawing.

      Support the sleeve

      Inspect the actual insertion and sleeve support to avoid probe movement or resonance.

      Protect the target

      Confirm case thread, target clearance and gap adjustment without tip contact.

      Seal the housing

      Inspect cover, O-rings, conduit port and specified plug against site requirements.

      Avoid rating inference

      Use actual CA/agency markings and the site drawing to assess hazardous-area suitability.

      Check the chain

      Record probe, extension cable, sensor and monitor channel before energization.

      Alternative Names

      Technical notes

      Code map: AA selects probe option, BB cable, CC standoff, DDD penetration, EE fittings and FF mounting thread.

      Mechanical boundary: The 7.0 in penetration must be checked against the machine case and target; the housing alone does not define final gap.

      FAQ View All FAQ

      • How should the installed probe assembly be compared with 21000-33-10-00-070-04-02?
        Compare all six groups, photos of the offered housing and probe, and the original drawing; nominal housing family alone is insufficient.
      • What can make 21000-33-10-00-070-04-02 unsuitable even when its mounting thread fits?
        Penetration, sleeve support, probe target and conduit route may differ. Check these mechanical interfaces before installation.
      • How is the probe chain completed for 21000-33-10-00-070-04-02?
        Identify the included 8 mm probe and 1.0 m lead, then select a matching extension cable and 8 mm Proximitor Sensor for the intended system length.
      • Why should sleeve support be reviewed for 21000-33-10-00-070-04-02?
        Long insertion can allow movement or resonance. Compare the actual C plus D dimension and installed support against the manufacturer guidance.
      • Does the fitting group of 21000-33-10-00-070-04-02 establish an explosion-proof rating?
        No. Assess the actual housing version, approval marking, fitted components and site drawing together; the source treats CA housing approvals separately.
      • What seals and closures should be inspected on 21000-33-10-00-070-04-02?
        Inspect the dome cover, O-rings, thread seal, plug and conduit interfaces before closing the assembly.
      • How should the probe gap be accepted after fitting 21000-33-10-00-070-04-02?
        Set the gap using the approved machine procedure and matched transducer chain, then record static output and controlled response.
      • What should be recorded when 21000-33-10-00-070-04-02 is handed over?
        Keep photos of the full marking, housing/fitting contents, mounted penetration, probe chain and monitored acceptance result.
