Expert Transient data recorder
Reliable data acquisition for clear decisions
Whether analyzing fault events, in test mode or in quality control - with the Expert Transient transient recorder you always have an overview. The system records analog and digital signals synchronously and with high accuracy, so that even the smallest details are reliably documented.
For you, this means: maximum data security through parallel internal and external storage, flexible scalability from a few to over 100 measurement channels and convenient visualization and analysis of your measurement data with modern measurement technology software.
This allows you to transform complex measurement tasks into clear information - and create a secure basis for quick and well-founded decisions.

Functions
Expert Transient - Full control over every signal
The Expert Transient records analog and digital measured values fully synchronously, enabling precise temporal analysis of event chains. Data is stored permanently or triggered - including the pre- and post-history of an incident.
- Everything in view - even with fast processes - Expert Transient records analog and digital signals fully synchronously with a sampling rate of up to 50 kHz per channel and 24-bit resolution. This means that even very short disturbances or fast signal progressions are precisely detected and reliably documented.
- Flexibly measure what really counts - With permanent or triggered recording, the measurement strategy can be optimally adapted. Thanks to flexible trigger conditions, pre- and post-histories of events can be recorded precisely.
- Precision and safety in every detail - Up to 16 galvanically isolated analog inputs and 4 synchronous digital inputs ensure exact reconstruction of event chains. The system can be expanded to more than 100 channels via the CAN interface - for maximum flexibility.
- Fast response in an emergency - Fast digital outputs are available if limit values are exceeded. In addition, alarms can be triggered automatically by e-mail or SMS - for immediate information and maximum safety.
- Reliable data storage without compromise - All measured values are securely stored in the internal 32 GB memory or backed up in parallel on an external NAS. This means that no data is lost - even with long-term recordings.
- Time synchronization for clear analyses - Measured values can be precisely synchronized via GPS, NTP or PTP. This allows even complex systems to be analyzed precisely and fault events to be tracked to the millisecond.

Versions
Expert Transient - From compact to extended: design as required
Expert Transient is available in versions with 4, 8, 12 or 16 analog inputs and 4 digital inputs and can be expanded to up to 100 channels via extensions. A 32 GB data memory is available for stand-alone use; alternatively, measured values can be stored in parallel on an external NAS with virtually unlimited capacity. The Expert Transient therefore offers maximum safety and flexibility both in the laboratory and in the field.

Software channels as extended functions
Realise and execute monitoring and automation tasks easily
Our measuring and testing devices have extended functions, which are summarized under the term software channels. The online measurement data is offset against the software channels and then used for visualization, storage or control.
In this way, entire programme sequences can be configured very simply and intuitively with the regulation and control function. These then run autonomously without PC support. This is how you use your data logger effectively, also as a monitoring device or PLC replacement.
The software channels enable functions such as limit value monitoring, integration or online calculation and are configured very easily. This means that even users who are not experts in programming can easily implement their own monitoring tasks or balancing independently in the unit.
