Description
Bently 21000‑16‑10‑00‑040‑03‑02
- Technical Specifications
- Compatible Probe: 3300 XL 8 mm reverse‑mount proximity probe
- Housing Main‑body Material: Aluminium alloy
- Sleeve Material: 304 stainless‑steel probe sleeve
- Standoff Adapter: Zero stand‑off (code 00)
- Probe Penetration Depth: 4.0‑inch penetration (code 040)
- Fitting Kit (code 03): NPT plug, reducer fitting, multi‑size cable‑seal gland and grommet accessories
- Mounting Thread: 3/4‑14 NPT thread (code 02)
- Enclosure Certification: CSA Type 4, explosion‑proof, fully compliant with API‑670 standard
- Functional Features: Zero‑stand‑off flush‑mount design suits compact installation conditions. Medium‑length penetration sleeve matches medium‑thickness bearing‑housing walls. Explosion‑proof all‑metal housing shields probe hardware from mechanical damage and plant‑site contaminants. Full O‑ring sealing system prevents oil mist, dust and moisture entry. Side conduit ports deliver protected routing for probe cables. All required installation fittings included in delivery. Maintains stable probe‑shaft spatial offset under long‑term equipment vibration.
- Application Scenarios: Centrifugal compressors, medium‑size steam turbines and large process pumps inside petrochemical and power‑generation facilities. External probe installation on medium‑thickness bearing housings with unobstructed mounting face. Hazardous‑area monitoring projects conforming to API‑670 specification.
- Performance Parameters: Stable spatial relationship preserved between probe and rotating‑shaft target under continuous machinery vibration. Sealing assembly works reliably under hot oily plant atmosphere. Enclosure satisfies explosion‑proof requirements for classified hazardous locations.
- Material Composition: Aluminium alloy housing main‑body; 304 stainless‑steel probe sleeve; corrosion‑resistant elastomer O‑ring sealing parts; metal dome cover and NPT conduit fittings.
- Structural Characteristics: Pre‑assembled assembly including dome cover, housing body, probe sleeve, sealing O‑ring set and conduit accessory kit. Dome cover connected via threaded interface. Side threaded ports for field‑site metal conduit connection.
- Working Principle: Mechanical protective fixture for reverse‑mount eddy‑current proximity probe. Probe fixed inside sleeve assembly. Entire housing unit threads directly onto outer surface of bearing housing. Assembly holds probe at stable position relative to rotating‑shaft target and provides mechanical shielding and environmental sealing. Probe achieves non‑contact displacement and vibration measurement based on eddy‑current sensing effect.
- Installation Requirements: Apply suitable thread‑seal compound on mounting threads. Verify all O‑ring components sit correctly within grooves before closing dome cover. Adjust probe penetration depth so static gap is inside probe linear working range. Attach field‑site conduit to housing threaded port. Tighten dome‑cover thread completely to preserve explosion‑proof enclosure integrity.
- Usage Notes: Avoid mechanical impact toward probe sleeve during handling and installation. Do not place equipment into operation with damaged or missing sealing components. Perform regular inspection of dome‑cover tightness on high‑vibration machinery. Any mechanical modification to housing assembly is strictly forbidden. Maintenance activities inside hazardous zones must comply fully with local site safety regulations.
