Function and Working Principle
The housing does not measure vibration directly. Instead, it serves as a protective and mechanical interface for proximity probes.
Working Principle
- A proximity probe is installed inside the housing.
- The probe is positioned close to a rotating shaft.
- It measures shaft displacement and vibration without physical contact.
- The housing ensures:
- Stable probe positioning
- Environmental protection
- Safe cable routing
- External access for maintenance
This setup is essential for accurate radial vibration and axial position monitoring in critical rotating machinery.
Role in Condition Monitoring Systems
- Provides protected mounting for proximity probes
- Enables measurement of shaft vibration and position
- Supports turbine supervisory instrumentation (TSI) systems
- Allows safe maintenance without machine shutdown
- Improves reliability of vibration measurement systems
- Supports hazardous area industrial installations
Industrial Applications
- Steam, gas, and hydro turbines
- Centrifugal and axial compressors
- Large industrial pumps
- Gearboxes and drive trains
- Power generation equipment
- Oil & gas rotating machinery
- Petrochemical process equipment
Installation Guidelines
- Mount externally on machine casing or bearing housing
- Ensure rigid and vibration-stable installation
- Use proper conduit sealing for hazardous environments
- Maintain correct probe gap alignment to shaft surface
- Verify probe sleeve length and clearance before installation
- Ensure compliance with plant safety and explosion-proof requirements
Proper installation is critical for accurate proximity measurement performance.
