Description
Bently 21504‑000‑076‑05‑02
- Key Features: Hermetically sealed sensing coil unit; threaded installation interface; 0.5 m integral coaxial cable; microdot connector termination; stable output under industrial electromagnetic interference environment.
- Technical Specifications & Performance Parameters
- Integral cable length: 0.5 m
- Operating temperature range: ‑40 ℃ ~ +85 ℃
- Storage temperature: ‑55 ℃ ~ +125 ℃
- Frequency response: 0‑10 kHz
- Weight: 0.24 kg
- Material Composition: Stainless‑steel probe housing and thread body; high‑stability copper sensing coil; PTFE‑insulated coaxial cable; metal shielding braid; epoxy sealing resin; microdot connector assembly.
- Structural Features: Cylindrical probe main‑body with external mounting thread; rear‑exit integral coaxial cable; microdot connector at cable terminal; fully sealed coil internal cavity for dust‑proof and moisture‑proof performance.
- Working Principle: Proximitor transmits high‑frequency excitation signal into probe coil. Eddy‑current effect takes place on metallic shaft surface. Gap‑distance variation changes coil impedance value. Proximitor converts impedance fluctuation into proportional DC gap‑voltage output signal.
- Application Scenarios: Petrochemical plant pump and blower shaft‑condition monitoring; retrofitting of legacy 7200 online‑protection systems; spare‑part replacement for field‑failed probes.
- Installation Requirements: Fasten probe into dedicated mounting bracket; tune initial gap position within linear measuring zone; fully lock microdot connector; sensor cables must run separately from power cables; implement single‑end shielding‑layer grounding.
- Usage Notes: Avoid mechanical impact on probe sensing tip; forbid sharp small‑radius bending on coaxial cable; maintain factory‑calibrated total cable length for probe‑extension‑proximitor assembly; keep microdot contacts clean and free from grease contamination.
