Technical notes

If a probe penetration length (C plus D) greater than 300 mm (12 in) is selected for the 21000-34-05-00-030-03-02, sleeve support must be added near the probe to prevent resonance from occurring. Bently Nevada offers a probe support and oil seal (part number 37948-01) for long sleeves that must go through an inner bearing housing on the 21000-34-05-00-030-03-02. Custom sleeve lengths are also available for the 21000-34-05-00-030-03-02 upon request.

Thread Engagement: Screw the lower housing sleeve into the machine casing port, ensuring a minimum of 5 full threads of NPT engagement for a secure mechanical seal.
Penetration Depth: Verify the 3.0-inch (-030) exposure aligns properly inside the machine cavity so the tip avoids undesired side-view or rear-view boundary interferences.
Gap Adjustment: Position the reverse-mount proximity probe internally to allow external access for gap voltage tuning without tearing down the primary machine bearing housing.
