Function and Working Principle
The 190501-12-00-05 continuously measures vibration velocity generated by rotating equipment and converts it into an electrical output signal for monitoring and analysis.
Main Functions
- Continuous vibration monitoring
- Machinery condition assessment
- Early fault detection
- Predictive maintenance support
- Equipment protection and reliability enhancement
- Operational performance monitoring
Working Principle
The sensor utilizes a precision piezoelectric sensing element that responds to machine vibration. Mechanical vibration causes the element to generate an electrical signal proportional to vibration velocity. This signal is transmitted to monitoring systems where vibration levels, alarm conditions, and machinery health trends can be evaluated.
The Velomitor CT design is optimized for low-frequency measurements, making it highly effective on slow-speed rotating machinery.
