Technical Specifications: Probe tip diameter: 8 mm Built‑in cable length: 1.0 m Mounting thread: M10×1 metric thread Scale factor: 7.87 V/mm Linear measuring range: 0.25 mm‑2.3 mm Recommended installation gap: 1.27 mm Frequency response: DC‑10 kHz Cable rating: extended‑temperature resistant
Functional Features: Extended‑temperature‑resistant cable withstands continuous higher ambient operating temperature Full interchangeability with all 3300 XL 8 mm‑series transducer‑system components Non‑contact measurement without mechanical wear Low temperature‑drift performance Strong anti‑electromagnetic‑interference capability Output stable static‑position and dynamic‑vibration measuring signals
Application Scenarios: Vibration and displacement monitoring for rotating equipment located adjacent to high‑temperature casings and hot pipelines. Applied for turbine and compressor monitoring within thermal‑power‑plant and petrochemical‑complex facilities.
Performance Parameters: Probe tip operating temperature: −52 °C ~ +177 °C Extended‑temperature cable operating temperature: −52 °C ~ +260 °C Probe coil resistance: 7.59 Ω ±0.5 Ω Maximum relative humidity: 93 % non‑condensing Scale‑factor tolerance: ±5 % over full linear measuring range
Material Composition: Probe tip: high‑temperature epoxy encapsulation Probe housing: 316 stainless steel Internal sensing coil: high‑temperature‑resistant enameled copper wire Cable outer jacket: special fluoropolymer high‑temperature insulating material Connector assembly: nickel‑plated alloy circular connector
Structural Features: Integrated probe‑cable one‑piece assembly M10×1 male mounting thread Hermetically sealed probe‑tip assembly Tri‑axial fully‑shielded high‑temperature signal cable Standard locking‑type miniature circular connector Anti‑vibration mechanical construction for long‑duration continuous‑running equipment
Working Principle: Eddy‑current sensing principle applies. High‑frequency magnetic field generated by probe coil induces eddy currents on metal‑target surface. Gap‑distance variation changes probe‑coil impedance value. Proximitor sensor converts impedance fluctuation into analog DC‑voltage signal proportional to clearance between probe tip and target surface. High‑temperature‑grade cable maintains signal integrity under elevated thermal surroundings.
Installation Requirements: Probe‑installation axis keeps strictly perpendicular orientation to target metal surface Prevent direct high‑temperature radiation from acting upon cable outer sheath Minimum static cable bending radius: 25 mm Separate signal‑cable routing from high‑voltage power‑cable routes Fully lock connector after plug‑in completion Reserve proper cable slack for equipment thermal‑expansion displacement
Usage Notes: Factory‑integrated probe‑cable assembly must not be cut or spliced Avoid mechanical‑collision impact to probe tip during installation and maintenance Measured target surface maintains clean bare‑metal condition Confirm cable temperature rating matches actual site thermal‑environment condition Inspect connector anti‑loose state periodically during long‑term equipment operation
