Data loggers function as the link between the on-site detectors and the monitoring center. They safeguard the detectors’ power supply, import their readings and buffer the data for transmission to the monitoring center. Today, great importance is attached to data communication with the monitoring center, not least because the development of data transfer systems is progressing at lightning speed. The data logger must ensure the secure exchange of data, be able to support various data transmission media and must be easily adaptable for changing data transmission technology. Even redundant data links may be required for enhanced availability and the data logger must be capable of implementing them. The DLM1470 data logger fully meets all these requirements. Thanks to its embedded PC ENVILOG, it offers all necessary functions along with the flexibility of being able to adapt continually to the rapidly changing communication media.
