Function and Working Principle
The 190501-19-00-04 continuously measures vibration velocity generated by rotating machinery and converts it into an electrical signal for monitoring and analysis.
Main Functions
- Continuous vibration monitoring
- Machinery condition assessment
- Early detection of mechanical faults (imbalance, misalignment, bearing wear)
- Predictive maintenance support
- Equipment protection and reliability improvement
Working Principle
The sensor uses a piezoelectric element that generates an electrical signal proportional to vibration velocity. When mounted on a machine casing or bearing housing, it captures mechanical vibration and transmits the signal to monitoring systems for analysis.
Its low-frequency optimization makes it particularly effective for slow-speed rotating equipment, where accurate vibration measurement is critical.
