Functional Features
- Advanced eddy-current non-contact measurement
- Extended 70 mm case length for deep mounting applications
- TipLoc molding for robust probe tip attachment
- CableLoc design providing 330 N (75 lbf) pull strength
- ClickLoc connector with positive locking feedback
- Full interchangeability within 3300 XL 8 mm systems
Application Scenarios
- Radial vibration monitoring on large turbines
- Shaft position measurement on generators
- Machinery protection in power generation facilities
- Condition monitoring on heavy industrial equipment
- Applications requiring deep probe mount engagement
Performance Parameters The probe provides a linear voltage output proportional to the gap distance. The 70 mm case length offers enhanced mounting stability in applications where the probe must pass through thick machine housings or bearing caps.
Material Composition
- Probe Tip: Polyphenylene Sulfide (PPS)
- Probe Case: AISI 303 or 304 stainless steel
- Cable: FEP insulated triaxial cable
- Connector: Gold-plated miniature coaxial ClickLoc
Structural Characteristics The probe features a 70 mm overall case length with zero unthreaded segment. The M10 × 1 metric thread ensures compatibility with standard metric mounting hardware. The 1.0 meter integral cable terminates in a miniature coaxial ClickLoc connector.
Working Principle The probe generates a high-frequency electromagnetic field at its tip. When a conductive target is present within the sensing range, eddy currents are induced in the target material. The Proximitor sensor detects the resulting impedance change and outputs a DC voltage proportional to the physical gap.
Installation Requirements
- Mount perpendicular to the shaft axis
- The 70 mm case length requires adequate clearance for full thread engagement
- Use M10 × 1 thread for secure mounting
- Set initial gap to produce -9 Vdc to -10 Vdc output
- Maintain proper shield grounding throughout the system
- Verify locking nuts are tightened to prevent vibration-induced loosening
Usage Precautions
- The extended case length requires verification of available mounting depth
- Must be used with compatible 3300 XL system components
- The CN suffix indicates regional compliance without altering technical performance
- Avoid over-tightening mounting nuts which could distort the probe body
- Regular inspection of probe alignment is recommended in high-vibration environments
- Connector protectors are recommended for all installations
