ExpertVibro-4 4 ch Vibration Analyzer

Expert Vibro - 4 Online Vibration Analyzer
 




Expert Vibro-4 Vibration Analyzer

The Expert Vibro is equipped with 4 synchronous analog inputs with sampling rates of up
to 50kHz per channel. It uses a 24-Bit A/D converter to guarantee a high-precision
measurement. Channels are all galvanically isolated from each other. This prevents the occurrence of any transverse interference between channels. Integrated comparators and digital inputs allow flexible triggering. Measurement data is monitored "on the fly" with up to 8 digital outputs that can be switched within msecs in the event of limit value violations.

 

Software channels are available to systematically group limit value violations into batch alarms. Instead of using digital outputs, alarms can also be processed via fieldbus interfaces. Characteristic values or raw time signals from analog inputs can be output to two analog outputs.
