Function and Working Principle
The 190501-11-00-04 continuously measures vibration velocity generated by rotating machinery and converts the mechanical motion into an electrical signal suitable for analysis and monitoring.
Main Functions
- Continuous vibration monitoring
- Machinery health assessment
- Fault detection and diagnostics
- Predictive maintenance support
- Equipment protection monitoring
- Reliability improvement programs
Working Principle
The sensor contains a precision piezoelectric sensing element that reacts to machine vibration. When vibration occurs, the internal element generates an electrical signal proportional to vibration velocity. This signal is transmitted to monitoring systems where vibration levels, alarm conditions, and machinery trends can be evaluated.
Its low-frequency optimization enables accurate monitoring of slow-speed machinery that may not be effectively measured using conventional vibration sensors.
