The bar display shows the following information:
● The position of a measured value within the set measuring span (e.g. pressure).
●
The position of the temperature value within the sensor limits.
● The scaling of the process values calculated from the pressure value (e.g. volume flow).
7.2.2.1 Display of measured values
The following measured values are always displayed:
● Pressure (P1)
● Sensor temperature (P2)
● Electronics temperature (P3)
● Percent of range (P9)
● Loop current (PA)
● Terminal voltage (PB)
The following values are calculated from the measured pressure value and are displayed
depending on your application:
● Level (P4)
● Volume (P5)
● Volume flow (P6)
● Mass flow (P7)
● Customized characteristic curve (P8)
