Function and Working Principle
The 190501-12-99-00 continuously measures vibration velocity produced by rotating machinery and converts the mechanical motion into an electrical signal for analysis and monitoring.
Main Functions
- Continuous vibration monitoring
- Machinery condition assessment
- Early fault detection
- Predictive maintenance support
- Equipment reliability improvement
- Machinery protection system integration
Working Principle
The sensor contains an internal piezoelectric sensing element that responds to machine vibration. When vibration occurs, the sensing element generates an electrical signal proportional to vibration velocity. The signal is transmitted to a monitoring system where vibration levels, alarms, and condition trends can be evaluated.
Its design is optimized for low-frequency vibration measurements, enabling accurate monitoring of slow-speed machinery that may be difficult to assess using conventional accelerometers.
