Description
Bently 21504‑000‑012‑05‑02
- Key Features: 12 mm large‑diameter probe tip; broader linear measuring range; standard threaded mounting; 0.5 m built‑in coaxial cable; epoxy sealed coil assembly; adapt for large‑shaft target surface.
- Technical Specifications & Performance Parameters
- Probe tip diameter: 12 mm
- Integral cable length: 0.5 m
- Linear measuring range: 0‑3.0 mm
- Nominal sensitivity: 3.94 V/mm
- Operating temperature range: ‑40 ℃ ~ +85 ℃
- Storage temperature: ‑55 ℃ ~ +125 ℃
- Frequency response: 0‑8 kHz
- Weight: 0.28 kg
- Thread specification: 1‑14 UNF‑2A
- Material Composition: Stainless steel probe housing and threaded body; large‑aperture copper sensing coil; PTFE insulated coaxial cable; metal shielding braid; epoxy sealing material; microdot connector assembly.
- Structural Features: Larger cylindrical probe body; external 1‑14 UNF mounting thread; rear‑side 0.5 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 generates on shaft target surface. Coil impedance changes with gap variation. Proximitor converts impedance fluctuation into linear DC gap‑voltage output signal.
- Application Scenarios: Large‑scale steam turbine axial displacement measurement; heavy‑duty fan and large pump shaft‑vibration monitoring; equipment requiring larger working gap margin; retrofitting for legacy 7200 monitoring systems.
- Installation Requirements: Mount probe into dedicated heavy‑duty bracket; adjust initial gap within linear measurement zone; fasten microdot connector reliably; separate sensor cables from power cables; implement single‑end shielding ground connection.
- Usage Notes: Target shaft surface area must satisfy requirement matching 12 mm probe tip; prohibit mechanical impact on probe front face; follow total calibrated cable‑length requirement of transducer system; keep connector contacts clean without oil and dirt pollution.
