Description
Bently 21504‑000‑040‑05‑02
- Key Features: Precision eddy‑current sensing assembly; epoxy hermetic sealing; threaded mounting structure; 0.5 m factory integrated coaxial cable; microdot connector termination; good electromagnetic interference resistance.
- 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: 0.22 kg
- Material Composition: Stainless steel mounting housing; wound copper sensing coil; PTFE insulated coaxial cable; metal shielding braid; epoxy sealing compound; microdot metal connector.
- Structural Features: Compact cylindrical probe structure; external mounting thread; rear‑exit integral coaxial cable; microdot connector for extension‑cable connection; moisture‑proof sealed internal coil chamber.
- Working Principle: High‑frequency alternating current excites probe internal coil. Eddy‑current occurs on conductive shaft surface. Gap variation brings coil‑impedance change. Proximitor converts impedance change into linear gap‑voltage analog output signal.
- Application Scenarios: Industrial compressor shaft‑vibration online monitoring; general‑purpose rotating‑machinery protection; spare‑part replacement for existing 7200 series monitoring cabinets.
- Installation Requirements: Secure probe inside dedicated mounting bracket; adjust initial working gap inside linear range; lock microdot connector completely; separate sensor wiring from high‑power cables; single‑end ground for shielding braid.
- Usage Notes: Prevent collision and scratch to probe sensing face; maintain minimum cable bending radius; do not alter total calibrated cable length of full transducer system; keep microdot contacts clean during overhaul.
