Key Features
- Reverse Mount Design: Installs from inside structure with probe tip facing outward
- Long 9.0m Cable: Often eliminates need for separate extension cable
- Multiple Agency Approvals: CSA, ATEX, and IECEx for hazardous locations
- Long Unthreaded Length: 2.0 inch (50.8mm) smooth section
- 11mm Diameter with 4mm Range: Large linear range
- TipLoc and CableLoc Technology: Strong mechanical bonds
- Miniature ClickLoc Connector: Compact connector for space-limited applications
Application Scenarios
- Oil and gas production: Monitors compressors, pumps, and turbines in hazardous area classifications
- Petrochemical processing: Measures shaft vibration in reactors and process equipment in explosive atmospheres
- Chemical plant rotating equipment: Monitors agitators and pumps handling flammable chemicals
- Offshore platform equipment: Certified for marine hazardous area installations
- Natural gas pipeline compressors: Monitors pipeline compressors in hazardous locations
- Refinery critical equipment: Measures vibration in catalytic crackers and reformers
- Internal mounting in hazardous areas: Reverse mount design for confined hazardous spaces
Performance Parameters Identical electrical performance to other 3300 XL 11mm probes. The 9.0 meter cable length provides more flexibility in probe placement. The hazardous location certifications ensure safe operation in specified explosive atmospheres.
Material Composition Identical to other 3300 XL 11mm probes with hazardous location certification requiring specific materials and construction methods.
Structural Characteristics Identical to 330705-02-18-10-02-00 but with 9.0 meter cable and miniature ClickLoc connector. The longer cable is significantly heavier. Certification labels are affixed to the probe.
Working Principle Identical to other 3300 XL 11mm probes.
Installation Requirements
- Install in accordance with all applicable hazardous location wiring codes
- Use certified cable glands or conduit seals for cable entry into hazardous area enclosures
- All other installation requirements identical to 330705-02-18-10-02-00
- Verify certification labels are intact and legible
Usage Precautions
- The hazardous location certifications are void if the probe is modified
- The 9.0m cable is heavy; provide adequate support
- All other precautions identical to 330705-02-18-10-02-00
