With VIBRONET Signalmaster, up to 162 measuring points can be installed and entire production areas can be included in the monitoring. The distance between the basic unit and the sensor does not play a decisive role, because the wiring concept used reduces installation costs to a minimum. VIBRONET Signalmaster is therefore one of the most efficient and cost-effective monitoring systems for large machinery and extensive plants with production-critical units.


Vibration, temperature, RPM and other process parameters can be integrated into a monitoring network that covers whole plant sections.The robust cabling installation guarantees reliable machine monitoring even in harsh environments such as cement plants, open-pit and underground mining or refineries. VIBRONET Signalmaster is easily expandable.


The data recorded can be analyzed in OMNITREND CENTER, the universal software platform for PRUFTECHNIK's Condition Monitoring systems.


Integration into intrinsically safe areas is most simple and cost-effective. With a maximum of three barrier devices, more than 100 vibration sensors can be implemented into ATEX zones.
