Description
Bently 21505‑000‑040‑10‑02
- Key Features: Epoxy‑sealed internal coil assembly; standard threaded mounting structure; 1.0 m factory‑integrated coaxial cable; microdot connector termination; good stability under continuous long‑time operation.
- Technical Specifications & Performance Parameters
- Integral cable length: 1.0 m
- Operating temperature range: ‑40 ℃ ~ +85 ℃
- Storage temperature: ‑55 ℃ ~ +125 ℃
- Frequency response: 0‑10 kHz
- Weight: 0.27 kg
- Material Composition: Stainless‑steel housing and threaded mounting body; precision‑wound copper sensing coil; PTFE‑insulated coaxial cable; metal shielding braid; epoxy sealing compound; microdot metal connector.
- Structural Features: Cylindrical probe main‑body with external installation thread; rear‑side outgoing 1.0 m integral coaxial cable; microdot termination connector; hermetically sealed coil chamber.
- Working Principle: High‑frequency excitation signal is delivered from proximitor to probe coil. Eddy‑current generates on conductive shaft‑target surface. Gap‑distance change causes coil‑impedance variation. Proximitor converts impedance variation into linear gap‑voltage analog output.
- Application Scenarios: Centrifugal compressor shaft‑vibration and axial‑displacement monitoring; field measuring‑points requiring longer probe integral‑cable; spare‑part replacement for original 7200‑system sensors.
- Installation Requirements: Install probe in dedicated mounting bracket; adjust initial gap inside linear working‑range; lock microdot connector completely; separate sensor cables and power cables; shielding layer implements single‑end grounding.
- Usage Notes: No collision or scratch on probe sensing tip; follow minimum‑bending‑radius requirement for coaxial cable; keep full‑set transducer total cable‑length consistent with factory calibration; clean microdot contacts during equipment maintenance work.
