Delphin - Model Expert Vibro -Vibration Measuring Device for Vibration Data Acquisition and Vibration Analysis
With Expert Vibro, we have succeeded in combining complex functions and the requirements for high flexibility in a user-friendly vibration measurement device. The vibration measurement device opens up new fields of application where the use of vibration measurement technology was previously not economically efficient.
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.
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 .
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.
- 4, 8, 12, 16 synchronous analog inputs, 50 kHz sampling rate per channel, IEPE, mV, mA sensors selectable via software
- Integrated comparators for KeyPhasor® sensors
- 32 GB data logger memory in the vibration meter
- 4 digital inputs for frequency measurement up to 1 MHz
- 4 analog outputs for monitoring
- 8 digital outputs
- Display for reading data on-site
Your benefits with Expert Vibro vibration measurement technology
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.

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.
Here you will find an overview of the standard and optional hardware interfaces and protocols Learn more about the variety of interfaces of our measurement technology software.
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.
