Piezoelectric sensors
Specialized in high frequency (over 1,000 Hz) vibration detection. Suitable to acceleration monitoring.
Multi-channel
Maximum 12 channel per 1 system is available. Range and function can be set individually per every channel.
Application Example
Cables are laid out between sensors located on a large sized motor of home power generator and a monitoring system housed in a control panel. Monitoring systems can monitor vibration values and output the alarm in an emergency.
