Original Press Release:

New 4-Channel ET-4 Expert Transient from Delphin

CAS DataLoggers, in partnership with Delphin Technology, introduces a new model of the Expert Transient data acquisition system, the 4 channel ET-4. Designed for data acquisition and fault diagnostics, this system is especially suited for smaller applications that only require a few analog input channels. A key feature of the Expert Transient family of is the ability to synchronously acquire multiple analog channels at sample rates up to 50 kHz. The ET-4 can operate as a standalone device recording to internal memory to capture both transient and periodical data.

In the event of a fault, this enables precise identification of the sequence of events in a malfunction. Measurement data can be recorded either continuously or according to trigger conditions and events including the ability to define triggers to record pre- and post-event data. The ET-4 is equipped with powerful FPGA technology that provides extensive on-board intelligence for calculations, logic, and data analysis.

In addition to the 4 analog input channels, the ET-4 has 4 digital inputs to capture pulses, discrete inputs or digital triggers. An extension bus allows the system to be extended to over 100 analog or digital inputs with high-speed synchronization protocols.

Features:

  • 24 Bit A/D for high resolution measurements
  • 4 Analog outputs
  • 8 Digital outputs
  • Programmable anti-alias filtering
  • Up to 14GB of local non-volatile memory
  • Support for USB, NFS, CIFS data storage, and FTP/SFTP file transfer
  • Gigabit Ethernet interface, optional 802.11 b/g/n Wi-Fi
  • RS-232, RS-485, CAN, ModBus RTU, ModBus TCP, and PROFIBUS interfaces

Powerful Expansion Software:

Data captured by the ET-4 can be displayed on a PC in trend charts using Delphin’s ProfiSignal Go software. Even large volumes of historical data are easy to analyze – Profisignal Go has been optimized to enable large data volumes to be easily processed online. For on-line applications live data can be streamed to a PC via a GB Ethernet or WiFi interface and data recorded in the device’s internal storage can be easily downloaded and analyzed offline. Go also features a signal sequence diagram is especially useful in providing an overview of the chronology of a malfunction event.

The Delphin Expert Transient is designed for applications that require high speed acquisition of transient or periodic signals including:

  • Fault diagnostics on machines, systems and test stands
  • Evaluation of pressure surges and pulses
  • Capturing transient voltage or current events in electronic equipment
  • High-speed process monitoring and controller optimization
  • Crash, detonation, impact and explosion experiments
  • Shock and vibration measurement
  • Materials research and environmental simulation
