- Material Composition: AISI 304 stainless‑steel long‑length probe housing and threaded body; precision‑wound high‑stability copper sensing coil; PPS polymer probe tip; FEP triaxial insulated inner cable; gold‑plated brass Mini‑Dot connector; high‑temperature epoxy hermetic sealing compound.
- Structural Features: Extended cylindrical probe main‑body with external 3/8‑24 UNF mounting thread; TipLoc molded sealed probe‑tip assembly; rear‑exit flexible non‑armored integral triaxial cable; Mini‑Dot termination connector; CableLoc reinforced junction between probe housing and cable; fully sealed internal coil cavity against oil mist, dust and moisture ingress.
- Working Principle: Matched proximitor module generates high‑frequency radio‑frequency excitation signal. Signal transmits through triaxial cable to internal sensing coil inside probe tip. Alternating electromagnetic field induces eddy‑current on conductive metallic shaft surface. Coil impedance value changes proportionally to physical gap distance between probe tip and shaft target. Proximitor converts impedance variation into DC gap‑voltage plus AC vibration signal for machinery monitoring racks.
- Application Scenarios: Deep‑recess measuring‑points inside turbine and compressor bearing housings; steam turbine shaft‑vibration and thrust‑displacement monitoring; petrochemical TSI system spare‑part replacement; retrofitting of legacy 3300‑XL monitoring installations; rotating‑machinery requiring long‑body probe mounting.
- Installation Requirements: Screw probe into dedicated deep‑recess machined mounting bracket with controlled torque value; keep probe tip perpendicular to shaft target surface; adjust initial operating gap to sit within linear measuring zone; fasten Mini‑Dot connector locking ring completely; route sensor cables separately from high‑power motor and inverter power cables; implement single‑end shielding grounding for triaxial cable shielding layers; confirm total calibrated system cable length matches proximitor configuration.
- Usage Notes: Prohibit mechanical impact or scratch to PPS probe‑tip surface; avoid sharp small‑radius bending for non‑armored triaxial cable assembly; maintain minimum cable bending radius as defined in factory datasheet; never cut or splice integral probe cable section; keep Mini‑Dot connector gold contacts clean from oil, dust and water contamination; inspect connector tightness during each unit overhaul cycle.
