Industrial Applications
Turbomachinery Monitoring
Monitor journal bearing clearance, thrust position, and rotor vibration in steam turbines, gas turbines, and centrifugal compressors.
Large Motors & Generators
Track rotor position and vibration in electric motors above 1,000 HP. Prevent bearing failures and rotor-to-stator contact.
Process Pumps & Compressors
Measure shaft displacement and vibration in oil & gas applications. API 670 compliance required for machinery protection systems.
Predictive Maintenance
Enable condition-based maintenance strategies that reduce emergency repairs by 40-60% and extend equipment life.
Installation Guidelines
Best Practices
- Gap Setting – Install with 1.0-1.5mm (40-60 mils) gap to shaft surface
- Perpendicular Alignment – Probe tip must be perpendicular to shaft (±5° tolerance)
- Target Surface – Ensure smooth, clean shaft surface free of keyways or scratches
- Cable Routing – Avoid sharp bends, keep away from power lines (300mm minimum)
- Grounding – Ground cable shield at proximitor end only

FAQ
Q: What is the difference between proximity sensors and accelerometers?
A: Proximity sensors measure shaft displacement (absolute position), while accelerometers measure vibration. Both are complementary.
Q: Can I use this sensor with non-steel shafts?
A: Sensor requires conductive target material (steel, stainless steel, Inconel). Not compatible with ceramic or composite shafts.
Q: How often should I recalibrate?
A: API 670 recommends recalibration every 5 years or after cable replacement. Annual field verification recommended.
