Product Series Information
990 Series Proximity Transducer System
The 990 Series is a compact shaft monitoring product family designed for direct measurement of rotating shaft movement.
The series uses non-contact eddy current technology to measure the relative distance between the sensor probe and the machine shaft.
Compared with traditional vibration measurement methods, direct shaft measurement provides more accurate information about rotor behavior and mechanical operating conditions.
The 990 Series is suitable for machines where stable operation and early fault detection are essential.
Main Features of 990 Series
- Direct shaft displacement measurement
- Non-contact measurement technology
- Compact probe design
- High sensitivity
- Stable signal output
- Excellent repeatability
- Fast response capability
- Long service life
- Low maintenance requirement
- Suitable for continuous monitoring
Product Description
The 990-05-XX-01-05 147202-01 is a proximity transducer system designed to measure the movement of rotating shafts with high accuracy.
The system consists of several main components:
- Proximity sensing probe
- Extension cable
- Signal conditioning electronics
During operation, the probe creates an electromagnetic sensing field near the shaft surface.
When the shaft position changes, the electromagnetic characteristics change due to variations in eddy current generation.
The electronic system converts these changes into electrical signals proportional to shaft movement.
The measured information can be used for:
- Machinery protection
- Vibration monitoring
- Rotor condition evaluation
- Predictive maintenance
- Equipment performance analysis
Because there is no physical contact between the probe and shaft, the system provides long-term stable operation with minimal maintenance.
Operating Principle
The 990-05-XX-01-05 147202-01 works based on eddy current displacement measurement technology.
Measurement Process
- The probe generates a high-frequency electromagnetic field.
- The rotating shaft interacts with the electromagnetic field.
- Eddy currents are produced on the conductive shaft surface.
- Shaft movement changes the electromagnetic characteristics.
- The electronic circuit detects the variation.
- The system outputs a proportional signal representing shaft displacement.
This technology provides:
- Accurate shaft measurement
- High response speed
- Reliable signal stability
- Continuous monitoring capability
- Long operating durability
