Expert
Vibro is a device for acquiring transient signals and vibrations. The
latest processor technology, based on powerful FPGAs, enables 16
synchronous channels to be processed at high sampling rates while
requiring minimal space. 24-Bit A/D converters ensure high precision.
Users are able to switch between voltage measurement, IEPE or shaft
vibration sensors. Integrated comparators and digital inputs allow
flexible triggering. Measurement data is monitored "on the fly" with
digital outputs being switched within msecs in the event of limit value
violations.
Vibration measurement is made easy with Expert Vibro. Expert Vibro
provides users with analysis and monitoring functions, intelligent
signal processing, an independent data storage capability and versatile
fieldbus connections – all in a single device.
Users can select filters such as high, low, or bandpass with
rectifiers, integrators, differentiators or decimators to make up a
preprocessing sequence. Multiple preprocessing sequences are able to run
in parallel in order to evaluate an input signal for maximum
versatility. A touch display shows users important configuration and
measurement data onsite.
Expert Vibro data loggers measure, monitor and record fully
independently. Non-periodic signals (for ex. fault diagnostics) can be
precisely analyzed with the Expert Vibro. Using its continuous sampling
mode, even the smallest of irregularities are recorded. The Expert Vibro
system is equipped with its own internal data storage capability (32 GB
data logger memory), making it especially reliable and secure. The
system also performs fast limit value monitoring of time signals.
