Description

Transient recorder from Delphin Technology.

The Expert Transient is suitable for acquiring and analysing fast, transient and sporadic signals, as well as periodic and continuous processes. With this transient recorder speed is guaranteed by a high sampling rate of up to 50 kHz per channel and a high 24-bit resolution. Triggered data recording turns fault incidents into measurement data files, which results in making evaluation much easier.

You can adapt the transient recorder to your specific needs – from basic limit value monitoring, to characteristic value calculation – using its integrated software channels to process the measurement data independently of a PC. Serial interfaces enable connection to machine control systems. Additionally, data can also be transmitted via a bus system and recorded using a sniffer. Another benefit of this logger is that all channels are galvanically isolated from each other as well as from the integrated interfaces, therefore avoiding feedback.
