Bently Nevada 330104‑00‑14‑10‑02‑CN
Technical Specifications: Probe tip diameter: 8 mm Built‑in integrated cable length: 1.0 m Mounting thread: M10×1 metric thread Scale factor: 7.87 V/mm (200 mV/mil) Linear measurement range: 0.25 mm‑2.3 mm Recommended working gap: 1.27 mm (−9 Vdc output) Frequency response: DC‑10 kHz Certification: CN hazardous‑area approval
Functional Features: Non‑contact measuring mode eliminates mechanical wear between probe and target shaft Full component interchangeability among probe, extension cable and proximitor without recalibration Excellent long‑term temperature stability High‑level EMI and RFI noise suppression for heavy‑industrial field environment Supports simultaneous static position and dynamic vibration signal output Certified for installation inside classified explosive‑gas hazardous areas
Application Scenarios: Radial shaft vibration monitoring, axial thrust displacement measurement, Keyphasor phase reference and zero‑speed detection. Deployed on steam turbines, centrifugal compressors, large fans, generators, process pumps and gearboxes within power generation, petrochemical, oil‑gas processing and metallurgical hazardous‑area sites.
Performance Parameters: Probe tip operating temperature: −52 °C ~ +177 °C Storage temperature: −52 °C ~ +218 °C Probe coil resistance: 7.59 Ω ±0.5 Ω Maximum relative humidity: 93 % non‑condensing Measurement accuracy: ±5 % across full linear range
Material Composition: Probe tip: high‑temperature resistant epoxy composite encapsulation Probe housing: 316 stainless steel Internal sensing coil: high‑temperature enameled copper wire Outer cable jacket: fluoropolymer insulating material Metal connector assembly: nickel‑plated alloy
Structural Features: Integrated one‑piece probe‑cable construction M10×1 male mounting thread Hermetically sealed probe‑tip assembly Tri‑axial fully‑shielded signal cable Miniature circular locking connector for extension‑cable connection Compact tip profile for limited installation bore space
Working Principle: Operation follows eddy‑current effect. High‑frequency alternating current from proximitor sensor excites the internal coil inside probe tip. Alternating magnetic field penetrates air gap and induces eddy currents on conductive metal‑target surface. Eddy‑current activity changes the impedance value of probe coil. Impedance variation transmits back to proximitor and converts into stable DC‑voltage output directly proportional to clearance distance between probe tip and target surface.
Installation Requirements: Mount probe axis strictly perpendicular to measured metal‑target surface Ensure target surface area exceeds probe‑tip diameter Set initial working gap inside defined linear measuring range Reserve proper cable slack for equipment thermal expansion and mechanical vibration Minimum static cable bending radius: 25 mm Route signal cable separately from high‑voltage power cables Fully lock connector after mating to avoid loose contact Comply with local hazardous‑area installation regulations for CN‑certified hardware
Usage Notes: Reference target material is AISI 4140 steel; sensitivity offset occurs when measuring other metal alloys Do not cut, splice or modify factory‑integrated probe cable assembly Avoid sharp extrusion, sharp bending and mechanical impact upon probe tip and cable Prevent corrosive process fluid from contacting probe tip and connector Operational temperature shall never exceed rated temperature limits Inspect connector locking status before system power‑on
