DTM user interface
For HART output signals, Profibus-PA and FF, a DTM is
available in accordance with the FDT-standard. The DTM
provides a self-explanatory and clear user interface for all
setup and control processes of the transmitter. For testing
purposes, it is also possible to simulate process values
and archive the parameter data.
Recording of the measured values is available for
diagnostic purposes.
Tank volume calculation
The additional tank volume calculation of the DTM
function can be used to reproduce any optional tank
geometry. The corresponding linearisation table is
generated automatically. The linearisation table can be
transferred directly to the transmitter.
