The TTF300 HART, PROFIBUS PA or FOUNDATION Fieldbus temperature transmitter in proven two-wire technology features a multitude of new functions and enhanced diagnostic information.

The field-mount temperature transmitter can be configured via FDT / DTM in DAT200 (Asset Vision Basic) or any standard FTD tool via EDD or local HMI (optional). For PROFIBUS the configuration is possible via GST-file, EDD or DTM and for FOUNDATION Fieldbus via EDD.
