5. Product Description
This model is built for high-reliability vibration and displacement monitoring in rotating machinery. The non-contact measurement principle ensures that there is no mechanical wear between the probe and the target surface, significantly improving service life.
The 5-meter system configuration provides flexibility for installations where the monitoring system is located far from the measurement point. The probe maintains signal integrity across this distance, ensuring accurate data transmission.
Its rugged housing and industrial-grade materials allow it to perform reliably in environments with oil, dust, moisture, and continuous vibration.
6. Applications
This probe is commonly used in the following applications:
- Steam turbines and gas turbines
- Compressors (centrifugal and axial)
- Industrial pumps
- Electric motors
- Gearboxes
- Oil & gas processing equipment
Typical monitoring functions include:
- Radial shaft vibration
- Axial position measurement
- Rotor displacement monitoring
- Speed and phase reference detection
7. Product Advantages
- Non-contact sensing eliminates mechanical wear
- High measurement accuracy and repeatability
- Stable signal over extended cable lengths
- Strong resistance to electromagnetic interference
- Durable construction for harsh industrial environments
- Suitable for hazardous and high-risk areas
- Easy installation and system integration
- Long service life with minimal maintenance
