5. Product Description
The 330103-07-14-05-01-00 is engineered for continuous and accurate monitoring of rotating shafts in industrial environments.
It uses eddy current technology to detect changes in distance between the probe tip and a conductive target. These changes are converted into electrical signals for monitoring systems.
The 07-14 mechanical configuration provides extended installation depth, while the 0.5 m system length allows deployment in tight spaces where cable routing is restricted.
The probe’s rugged design ensures long-term stability under harsh conditions such as vibration, oil exposure, and temperature variation.
6. Applications
Typical applications include:
- Steam turbines
- Gas turbines
- Compressors
- Pumps
- Electric motors
- Gearboxes
Measurement capabilities:
- Radial shaft vibration
- Axial displacement
- Shaft position monitoring
- Speed reference (Keyphasor function)
7. Product Advantages
High Precision Measurement
Provides consistent and accurate displacement readings.
Non-contact Operation
No mechanical wear, improving reliability and lifespan.
Compact Cable Configuration
0.5 m system length is ideal for confined installation environments.
Extended Housing Design
Supports deeper mounting positions where standard probes cannot fit.
Strong Environmental Resistance
Reliable in oil, dust, and high vibration conditions.
