Bently 31000‑16‑10‑00

Product Brief Introduction: The 31000‑16‑10‑00 belongs to Bently Nevada 31000 modernized proximity probe housing series, designed for external mounting of 3300 XL 8 mm reverse‑mount eddy‑current proximity probes. This housing uses advanced high‑performance PPS thermoplastic composite as main housing material, combined with stainless‑steel probe sleeve components, delivering superior corrosion resistance against chemical vapour, salt mist and humid industrial atmosphere compared with traditional 21000 aluminum housing. Zero‑standoff structural design supports direct flush mounting on bearing housing outer surface.

  • Functional Features: High‑performance PPS composite housing provides excellent chemical corrosion resistance against acid, alkali vapour and salt spray environment. Zero‑standoff flush‑mount design saves installation space on bearing housing outer surface. Stainless‑steel probe sleeve guarantees mechanical rigidity for probe installation. Multi‑O‑ring sealing system achieves IP66 water‑proof and dust‑proof performance. Adjustable probe penetration depth supports precise static gap calibration for eddy‑current transducer system. Side threaded ports support conduit connection for probe cable mechanical protection. External‑access design allows gap tuning and probe replacement without machine casing disassembly. Light‑weight composite housing reduces total assembly weight while retaining sufficient mechanical strength. This housing is not explosion‑proof and must not be deployed in explosive gas classified hazardous zones.
  • Application Scenarios: Non‑hazardous‑zone external mounting of 3300 XL 8 mm reverse‑mount proximity probes. Auxiliary rotating equipment such as large pumps, blowers and non‑classified compressors in power plants and chemical facilities. Machinery monitoring projects requiring high corrosion‑resistant housing without explosion‑proof certification requirement. Installation sites exposed to salt mist, high humidity and chemical vapour.
  • Performance Parameters: Composite housing maintains stable dimensional performance under wide temperature fluctuation. Multi‑O‑ring sealing assembly provides reliable IP66‑level dust‑proof and water‑proof protection. Mechanical structure retains fixed probe‑to‑target offset under continuous machinery vibration. Housing material will not interfere with electromagnetic field of matched eddy‑current proximity probe. Not suitable for gas‑classified hazardous‑area installation without explosion‑proof rating.
  • Material Composition: Main housing body adopts PPS polyphenylene sulfide high‑performance thermoplastic composite material. Probe sleeve is precision‑machined from 304 stainless steel. Sealing components are anti‑aging elastomer O‑rings. Internal metal reinforcing inserts are embedded in composite housing for threaded connection strength.
  • Structural Characteristics: Pre‑assembled unit consists of threaded composite dome cover, PPS main housing body, stainless‑steel probe sleeve, zero‑standoff mounting base and complete O‑ring sealing set. Dome cover connects with main housing body via threaded interface. Side threaded ports are reserved for field conduit connection. Internal cavity accommodates reverse‑mount proximity probe assembly. All sealing grooves are precisely machined for proper O‑ring positioning.
  • Working Principle: This assembly functions as mechanical fixture and corrosion‑resistant environmental protective enclosure for reverse‑mount eddy‑current proximity probe. Proximity probe is fixed inside stainless‑steel probe sleeve. Whole housing unit mounts flush externally onto bearing housing outer surface. Mechanical structure holds probe tip at stable spatial offset relative to rotating shaft target. Multi‑O‑ring seals isolate internal probe assembly from external dust, moisture and chemical vapour. Installed proximity probe completes non‑contact displacement and dynamic vibration measurement using eddy‑current inductive principle.
  • Installation Requirements: Apply suitable thread sealant onto mounting threads during field installation. Ensure all O‑ring components are fully seated inside corresponding grooves before screwing down dome cover. Adjust probe penetration depth to make static working gap stay within linear measurement range of matched 3300 XL 8 mm proximity probe. Connect field conduit to housing side threaded port for cable mechanical protection. Fully tighten dome‑cover thread to guarantee IP66 enclosure integrity. Confirm installation location belongs to non‑hazardous general industrial zone, never use inside explosive gas classified area. Follow API‑670 mechanical mounting guidance for proximity probe external installation.
  • Usage Notes: This housing assembly does not carry explosion‑proof certification, strictly forbidden for installation in hazardous classified zones. Avoid heavy mechanical impact to composite housing body during transportation and installation. Periodically inspect O‑ring aging condition under chemical vapour and high‑humidity environment. Do not apply excessive torque to composite dome cover to prevent thread cracking damage. Any field mechanical modification to housing assembly is prohibited.
