3.5

Mode of operation

In what follows, the mode of operation of the transmitter is explained using the function block

diagram.
The two versions of the SITRANS TH400 (7NG3214 ... and 7NG3215 ...) are distinguished

solely by the type of the fieldbus protocols (PROFIBUS PA or FOUNDATION fieldbus).
