Description
Delphin Technology Expert Vibro is the device for acquiring transient signals and vibrations. The latest processor technology, based on powerful FPGAs, enables 4, 8, 12 or 16 synchronous channels to be processed at sampling rates to 50 kHz per channel while requiring minimal space. 24-Bit A/D converters ensure high precision.
Vibration Measurement – Compact, Intelligent and Fast
With its Expert Vibro device, Delphin have successfully combined the processing of complex functions with high levels of flexibility in a user-friendly system. Vibration measurement systems can now be used where they had previously been economically infeasible. The device is equipped with a high powered, dual core FPGA processor based on ARM technology giving users ample reserves of processing power.
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 .
Vibrations deliver information on the condition of bearings, shafts and machinery and generally have a major affect on levels of quality in production processes. They should therefore be continuously acquired, intelligently evaluated and condensed into meaningful data for monitoring. In critical situations, machinery needs to be shut down within milliseconds.
Expert Vibro combines the requirements and functioning of modern vibration measurement systems into a highly compact device. Other systems usually require multiple equipment. Vibration measurement is made easy with Expert Vibro. System installation and familiarization are short so that users can quickly start processing their data.
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. Right from the outset, users save costs and avoid troublesome interface problems.
Of special benefit is the modular system for signal processing with a range of preprocessing functions. Filters, such as high, low, or bandpass with rectifiers, integrators, differentiators or decimators can be selected to make up a preprocessing sequence. Multiple preprocessing sequences are able to run in parallel in order to evaluate an input signal. This gives users an especially high level of flexibility.
Non-periodic signals, such as in fault diagnostics, can be analysed precisely using Expert Vibro. In continuous sampling mode, even the smallest of irregularities are recorded. Expert Vibro measures, monitors and records fully independently. Expert Vibro is equipped with its own internal data storage capability making it especially reliable and secure.

Delphin Technology Expert Vibro Functions
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.
Software Channels for Flexibility
Remote Monitoring and Independent Operation
Expert Vibro’s large data logger memory of up to 15 GB enables the device to run independently without the need for PC support. The memory can store raw signals, spectra and characteristic values and can be read out via USB, LAN or directly from the device using a USB flash drive. Password protection ensures authorized access only.
Expert Vibro also has wireless connectivity via local Wi-Fi networks or via UMTS and LTE. Wireless modules or a modem can be installed into the device. A slot on the device’s front is available for SIM card installation. Antenna connection is available at the device’s SMA connectors. The Expert Vibro’s touch screen is capable of displaying configuration or measurement data.
Delphin Technology Expert Vibro Applications
Monitoring & Observation
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.

Delphin Technology Expert Vibro Interface
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 supports this operation as a Modbus master or slave. The LAN interface transmits all data from measurements and software channels online and at high speed across the intranet or internet. Any networked PC can access the device via this interface. To measure vibrations from multiple channels, multiple Expert Vibro devices can be synchronized with each other.
