Description
Bently 21000‑16‑10‑00‑086‑03‑02
- Technical Specifications
- Compatible Probe: 3300 XL 8 mm reverse‑mount proximity probe
- Housing Body Material: Aluminium alloy
- Sleeve Material: 304 stainless‑steel probe sleeve
- Standoff Adapter: Zero stand‑off (code 00)
- Probe Penetration Depth: 8.6‑inch penetration (code 086)
- Fitting Kit (code 03): NPT plug, reducer, multi‑size cable‑seal gland and grommet accessories
- Mounting Thread: 3/4‑14 NPT thread (code 02)
- Enclosure Rating: CSA Type 4 enclosure, explosion‑proof, compliant with API‑670 standard
- Functional Features: Zero‑stand‑off direct‑mount profile fits flush against equipment outer casing. Extra‑long penetration sleeve adapts for very thick‑wall bearing‑housing construction. Explosion‑proof all‑metal housing protects internal probe against mechanical impact and plant‑site contamination. Complete O‑ring sealing set blocks ingress of oil mist, dust and moisture. Side conduit ports provide protected routing for probe extension cables. All installation‑related fittings supplied as complete kit. Retains stable probe‑shaft positional relation under sustained machine vibration.
- Application Scenarios: Large steam turbines and heavy centrifugal compressors fitted with thick‑wall bearing housings. Direct‑external‑mount installation where mounting surface has no surrounding spatial obstructions. Petrochemical and power‑plant hazardous‑area monitoring complying with API‑670 requirements.
- Performance Parameters: Maintains stable probe‑target position through continuous operational vibration. Sealing performance remains reliable under hot oily industrial environment. Enclosure meets explosion‑proof requirements for gas‑classified hazardous zones.
- Material Composition: Aluminium alloy housing main‑body; 304 stainless‑steel long probe sleeve; corrosion‑resistant elastomer O‑ring seals; metal dome cover and NPT pipe fittings.
- Structural Characteristics: Pre‑assembled assembly consists of dome cover, housing main‑body, long‑length probe sleeve, sealing O‑ring set and conduit accessory kit. Threaded dome‑cover connection structure. Side threaded ports for field‑site metal conduit connection.
- Working Principle: Mechanical protective fixture for reverse‑mount eddy‑current proximity probe. Probe secured inside sleeve assembly; housing unit threads directly onto bearing‑housing outer surface. Assembly fixes probe relative to rotating‑shaft target and delivers mechanical protection plus environmental sealing. Probe completes non‑contact displacement and vibration measurement on eddy‑current sensing principle.
- Installation Requirements: Apply suitable thread‑seal compound onto mounting threads. Confirm all O‑ring components correctly seated in grooves before closing dome cover. Adjust probe penetration depth so static gap falls within probe linear working range. Connect field conduit to housing threaded port. Fully tighten dome‑cover thread to guarantee explosion‑proof enclosure integrity.
- Usage Notes: Avoid impact damage to long probe sleeve during handling. Do not run equipment with damaged or missing sealing components. Regularly check dome‑cover tightening condition on high‑vibration machinery. Any mechanical modification of housing assembly is strictly prohibited. Maintenance operations in hazardous zones must comply with local safety rules.
