Transient data acquisition

For fast recording of non-periodic events and fault analysis

Synchronous and transient measured data acquisition

Transient measured data acquisition is a process in which time-dependent measured values are recorded. This may be necessary, for example, when investigating rapid physical or chemical processes. In transient data acquisition, it is important that the measuring devices have a high sampling rate in order to accurately record the rapid changes. In addition, the measuring devices must have sufficient resolution and sensitivity to be able to detect subtle differences in the measured values. Precise synchronization of the measuring devices and accurate time stamping of the data are also crucial in order to be able to correctly analyse the development of the process over time.

Whether in electrical networks or on systems, effects that cause faults usually only occur very sporadically. A single peak triggers an alarm. The task is to record this peak and analyze it together with its pre- and post-history. A long-term and complete recording is required. For this application, Delphin offers the Expert Transient device. 8 or 16 analog tracks are recorded in parallel and time-synchronously with a sampling rate of up to 50 kHz per channel. The transient data is stored on an internal or external memory (NAS). The Expert Transient appliances are very compact and space-saving. Behind the technology of Expert Transient There is no PC hidden in the PROFIBUS - the recording of the transient measurement data is correspondingly stable and reliable. In addition to the analog signals, it is also possible to "listen" to the PROFIBUS and record measurement data synchronously.

Application highlights of transient data acquisition

  • Transient data acquisition at sampling rates of up to 50 kHz
  • Synchronous measurement of analog signals
  • Sniffing function available for PROFIBUS measurement data
  • System extendible by up to 64 analog inputs

Practical example of transient measured data acquisition

Synchronous and transient acquisition of structure-borne noise

A military application examines ground sound-wave dispersal. Geophones are used at up to 48 sites to record high frequency data. The geophones provide an IEPE-compatible output signal which can be directly connected to an Expert Transient device. Three Expert Transient devices, each with 16 inputs, are being used for this purpose. Synchronous sampling is performed on the 16 analog inputs. The devices are linked to each other via a network. Synchronisation between the devices takes place using a PTP protocol. Absolute time synchronisation is performed via GPS.
