Expert Vibro

Manufacturer: Delphin Technology AG


Vibration measurement with state of the art processor technology

Expert Vibro is Delphin Technology's new device for acquiring transient signals and vibrations. The latest processor technology enables up to 16 synchronous channels to be processed at high sampling rates while requiring minimal space. 24-Bit A/D converters ensure high precision. Users may 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 a limit value violation.

Fully equipped –  compact design

  • 4 / 8 / 12 / 16 vibration inputs capable of being individually triggered
  • 50 KHz sampling rate per channel (∑ 800 KHz)
  • 15 GB data logger memory
  • 4 digital inputs for frequency measurement of up to 1 MHz
  • 4 analog outputs for monitoring purposes
  • Convenient DIN rail-mounting
  • Display capable of on-site graphic portrayal
  • Vibration Monitoring
  • Industrial Monitoring

User friendly configuration

Vibration measurement with Expert Vibro is user friendly. Intuitive configuration means fast installation and short training times. All relevant characteristic values are obtained from spectra and time signals. Spectra are calculated online and saved independently with time signals and characteristic values. Versatile software channels enable the Expert Vibro to perform complex analysis and monito- ring tasks. The Expert Vibro's touch screen can display configuration or measurement data.

A range of interfaces

Expert Vibro can be connected via LAN to the intranet/inter- net and via USB to PCs. For standalone applications, integrated Wi-Fi, UMTS or LTE modules are optionally available. Connection is via an antenna at the SMA connectors. In addition to two PROFIBUS interfaces, Modbus TCP is available to users for fieldbus connections. Multiple Expert Vibro devices can be synchronized with each other.

Complete system
ProfiSignal is a complete software system for data acquisition, analysis, visualisation and automation. The software is very user-friendly and combines professional functionality with easy operation. ProfiSignal provides a clear and logical overview of all measurement systems: whether for single or multi-thousand channel applications. For new users, ProfiSignal is quick to learn. ProfiSignal is modular, scalable and available in three versions: Go, Basic and Klicks. Each version has backward compatibility for operability, data files and application projects.

Measurement Database Included
Measurment hardware configuration takes place with the DataService / Configurator software included in ProfiSignal. The software configures hardware and software interfaces and records data securely and permanently.
The DataService saves measurement data to a database. Any ProfiSignal version on the network can then access these databases and immediately display their data as trends.
