9 Output signal coding
The 4–20 mA output supplies the current pressure in the
form of an analog value. The pressure measuring range is
scaled to 4–20 mA.
The Recommendation NAMUR NE43 (standardization of
the signal level for the failure information of digital transmit-
ters with an analog output signal) is used as a reference for
standardized error information (in addition to the measuring
information).
