Description

Bently Nevada 330105‑02‑12‑10‑02‑CN

Technical Specifications: Probe tip diameter: 8 mm Built‑in cable length: 1.0 m Mechanical structure: reverse‑mount configuration Scale factor: 7.87 V/mm Linear measuring range: 0.25 mm‑2.3 mm Recommended working gap: 1.27 mm Frequency response: DC‑10 kHz Certification: CN hazardous‑area approval

Functional Features: Reverse‑mount installation mechanical structure External gap‑adjustment capability without opening machine casing Full interchangeability with all 3300 XL 8 mm‑series transducer‑system components Non‑contact measuring mode Low temperature‑drift performance Hazardous‑area certified for explosive‑gas‑risk environment Strong anti‑interference performance

Application Scenarios: Vibration and displacement monitoring for rotating‑machinery equipment fitted with matching reverse‑mount probe‑housing assemblies. Deployed at refinery, chemical‑plant and power‑plant hazardous‑area locations where external probe‑gap adjustment is required.

Performance Parameters: Probe tip operating temperature: −52 °C ~ +177 °C Standard‑temperature cable operating temperature: −52 °C ~ +177 °C Probe coil resistance: 7.59 Ω ±0.5 Ω Maximum relative humidity: 93 % non‑condensing Scale‑factor tolerance: ±5 % Complies with API 670 standard and hazardous‑area safety specifications

Material Composition: Probe tip: high‑temperature epoxy encapsulation Reverse‑mount probe housing: 316 stainless steel Internal sensing coil: high‑temperature enameled copper wire Cable outer jacket: fluoropolymer insulating material Connector assembly: nickel‑plated metal‑alloy connector qualified for hazardous‑area service

Structural Features: Reverse‑mount mechanical body designed for rear‑side installation into probe‑housing assembly Special‑shaped probe‑body geometry matching standard probe‑housing hardware Hermetically sealed probe‑tip assembly Tri‑axial fully‑shielded signal cable Locking‑type miniature circular connector Mechanical dimensions compatible with 21000‑series probe‑housing assemblies

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. Reverse‑mount geometry only changes installation method without altering transducer measuring characteristics.

Installation Requirements: Must pair with corresponding reverse‑mount probe‑housing assembly Ensure probe‑tip surface stays perpendicular to target metal surface after full assembly Adjust probe working gap externally through housing rear port Signal‑cable routing maintains physical separation from high‑voltage power cables Minimum static cable bending radius: 25 mm Fully lock connector after plug‑in completion Strictly follow CN‑certified‑equipment hazardous‑area installation regulations

Usage Notes: Do not cut or splice factory‑integrated probe‑cable assembly Prevent mechanical‑impact damage to probe tip during gap‑adjustment operation Confirm probe tip will not collide with rotating‑shaft surface under maximum equipment thermal‑expansion displacement Measured target surface must retain clean bare‑metal condition All maintenance‑related operations within hazardous‑area zones must comply with local safety codes Inspect connector anti‑loose state periodically during long‑term equipment running
