Description
Bently 21505‑022‑055‑10‑02
- Key Features: Compact special‑size probe structure; epoxy hermetic sealing; 1.0 m built‑in coaxial cable; microdot connector termination; adapt narrow‑space mounting‑bracket installation condition.
- 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: 0.25 kg
- Material Composition: Stainless‑steel probe housing and threaded body; high‑stability sensing copper coil; PTFE‑insulated coaxial cable; metal shielding braid; epoxy sealing resin; microdot connector assembly.
- Structural Features: Special compact cylindrical probe body; customized‑spec external mounting thread; rear‑exit 1.0 m integral coaxial cable; microdot termination connector; fully sealed internal coil cavity.
- Working Principle: Proximitor outputs high‑frequency excitation signal to probe coil. Eddy‑current effect produces on metallic shaft‑target surface. Gap‑distance variation changes coil impedance value. Proximitor converts impedance fluctuation into proportional DC gap‑voltage output signal.
- Application Scenarios: Turbine casing narrow‑installation‑position measuring‑points; limited‑space shaft‑vibration monitoring; special‑retrofit projects of 7200 monitoring systems.
- Installation Requirements: Mount probe inside matched customized‑bracket; tune initial gap within linear‑measurement interval; fasten microdot connector reliably; separate sensor wiring and high‑power‑cable routes; shielding braid adopts single‑end grounding mode.
- Usage Notes: Strictly use matched customized mounting‑bracket; avoid mechanical impact to probe front sensing face; satisfy minimum‑bending‑radius requirement of coaxial cable; keep full‑set probe‑extension‑proximitor total calibrated cable‑length unchanged.
