- Material Composition: AISI 304 stainless‑steel probe housing and threaded mounting body; Keyphasor‑optimized precision‑wound copper sensing coil; PPS polymer probe‑tip; FEP triaxial insulated non‑armored cable; gold‑plated brass Mini‑Dot connector; high‑temperature epoxy hermetic sealing compound.
- Structural Features: Cylindrical probe main‑body with standard external mounting thread; TipLoc molded sealed Keyphasor‑optimized sensing tip; rear‑exit flexible non‑armored integral triaxial cable; Mini‑Dot termination connector; CableLoc reinforced cable‑housing transition; fully sealed internal coil cavity resisting oil mist and moisture ingress.
- Working Principle: Proximitor sends high‑frequency excitation signal through triaxial cable to Keyphasor probe coil. When shaft notch or projection passes probe tip, rapid gap‑distance change produces sharp impedance variation. Proximitor converts this rapid impedance change into clear Keyphasor trigger pulse. System calculates shaft rotating speed and absolute phase‑angle from pulse time‑interval data for rotor dynamics analysis and machine protection logic.
- Application Scenarios: Rotational speed and Keyphasor phase reference measurement for steam turbines; centrifugal compressors rotor phase monitoring; rotor orbit and dynamic‑vibration diagnostic analysis; 3500 rack Keyphasor‑module supporting measuring‑points; spare‑part replacement for legacy 3300‑XL Keyphasor probe installations.
- Installation Requirements: Mount probe into dedicated Keyphasor mounting bracket; align probe tip toward shaft notch or projection target; adjust trigger gap within effective trigger‑gap range; fasten Mini‑Dot connector locking ring completely; separate Keyphasor sensor‑cable routing from high‑power‑cable trays; implement single‑end grounding for cable shielding layers; validate trigger‑pulse output during machine barring‑rotation test.
- Usage Notes: Shaft notch geometry must satisfy factory‑defined Keyphasor target specification; mechanical collision to probe tip assembly is forbidden; maintain minimum bending‑radius for non‑armored triaxial cable; field cutting or splicing of integral probe cable must not be performed; keep Mini‑Dot connector gold contacts clean and dry; verify Keyphasor pulse integrity during every unit overhaul cycle.
