The Expert Vibro is equipped with 4, 8, 12 or 16 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.

Modular analysis

Versatile software channels enable the Expert Vibro to perform complex analysis and monitoring tasks. All relevant characteristic values are obtained from spectra and time signals. Spectra are calculated online (FFT) and saved with time signals and characteristic values. Users can modularly determine the analysis functions required for specific channels. Functions include high, low and band pass filters, integrators, FFT algorithms and many more.

Harmonic vibration monitoring is a typical requirement. Phase measurement delivers the necessary characteristic values. Odd harmonics can also be calculated, such as the blade passing frequency. To monitor frequency bands, speed-adaptive narrow-band characteristics are evaluated. Such characteristics are main frequency and a band's RMS (root mean square) or maximum amplitude.

Expert Vibro is suitable for many different types of application. It has universal sensor inputs which can be switched, via software, to the sensor type required. IEPE accelerometer, speed or vibration sensors are easy to connect.

Any type of voltage or current output sensor may be used – for example, fast pressure sensors for noise measurement/humming in combustion processes. Each input is individually configurable. Velocity and shaft vibration measurement can be performed simultaneously.

Expert Vibro can be connected to a network via a LAN interface or to a PC via a USB connection. For field bus connections, the device has two PROFIBUS DP Slave interfaces, a Modbus TCP and a Modbus RTU, and a user-configurable CAN interface.

The interfaces can alternatively be used to connect any other measurement equipment and sensors via RS232/485 ports. Expert Vibro is integrated into PROFIBUS via a GSD file. An option is available to switch operating mode to redundant (according to PNO 2.212 V1.2) PROFIBUS. The LAN and RS485 interface can also exchange data via the Modbus TCP/RTU protocol.

Expert Vibro is fully compatible with the ProfiSignal software and is available with the "Vibro" option. ProfiSignal is a complete software package for use in data acquisition analysis, visualization and automation.

The software is very user-friendly with specialist functions that are simple to operate. ProfiSignal is modular, scalable and available in the three versions: Go, Basic and Klicks.

• ProfiSignal Go: Software for measurement data acquisition
• ProfiSignal Basic: Software for process visualization and monitoring
• ProfiSignal Klicks: Software for process automation and measurement procedures
  
  

The ProfiSignal Vibro option extends ProfiSignal with the following diagrams:

• Spectrum (FFT)
• Spectrogram
• Cascade diagram
• Envelope spectrum
• Order analysis
