Industry Applications
Turbomachinery Vibration Monitoring
In steam turbines, gas turbines, and compressors, the system measures shaft relative vibration and axial position. Its DC-to-20 kHz bandwidth captures both slow drift and high-frequency vibrations, enabling early fault detection.
API 670 Machinery Protection
For API 670-compliant installations, this proximity system integrates seamlessly with VM600Mk2/VM600 and VibroSmart® monitoring systems. The temperature-compensated design ensures accuracy across varying thermal conditions, reducing false trips.
Installation & Setup Guidance
Mounting and Cable Routing
- Ensure the transducer tip is perpendicular to the target shaft surface within ±1°.
- Use the M10 × 1 thread for secure mounting in standard probe holders.
- Route the integral cable (1.0 m) and extension cable (total 10 m) away from high-voltage sources to avoid interference.
- Hand-tighten the self-locking miniature coaxial connectors until locked — do not use tools.
Environmental Considerations
- For Ex Zone installations, the transducer and cable can operate up to +195°C.
- The flexible stainless steel hose provides mechanical protection but is not leak-tight; use the FEP sheath option for chemical resistance.
Maintenance & Reliability
Inspection Intervals
- Periodically inspect the cable and connectors for damage, especially in high-vibration areas.
- Verify the transducer tip is free from debris or buildup that could affect measurement accuracy.
- Check the optional protection hose for kinks or abrasion.
Reliability Features
- The stainless steel body (AISI 316L) and Torlon tip resist corrosion and wear.
- Short-circuit protection on voltage or current output ensures safe operation during faults.
- The system is designed for long-term continuous use in machinery protection applications.
Compatibility & Integration
This proximity measuring system works with the IQS900 signal conditioner, which provides the high-frequency power source required for eddy-current operation. It is ideal for use with:
- VM600Mk2 and VM600 machinery monitoring systems
- VibroSmart® distributed monitoring systems
- Any API 670-compliant protection rack
Selection Guide & Purchasing Advice
Before ordering the 111-412-000-013-A1-B1-E010-F1-G010-H10, verify:
- System length: The total length is 10 m (1.0 m integral + 9.0 m extension).
- Optional protection: Choose flexible hose (F1) or FEP sheath based on environmental exposure.
- Ex certification: If required for hazardous areas, confirm the specific Ex version.
