transmitter is > 19.5 mA. If a transmitter fails, calculation continues with the unaffected transmitter if it
is in its measuring range.
17.17.1 dp mode
Operating mode for the differential pressure transmitter.
Selection: Default
Calculation with default value (only for test purposes)
ST
Measurement with 1 transmitter
ST rad
Measurement with 1 transmitter square rooted
DT
Measurement with 2 transmitters
DT rad
Measurement with 2 transmitters square rooted
EWZ211
Connection of a WZ200 transmitter
DT31x.1
Connection of a DT31x.1 with balancing
DT31x.1 rad
Connection of a DT31x.1 with balancing square root
DT31x.1 + ST
Connection of a DT31x.1 with bal ST
DT31x.1 + ST rad Connection of a DT31x.1 with bal ST square root
17.17.2 dp default
Default value for the differential pressure. Only for test purposes.
Range:
-3000.0 ... +3000.0 mbar dp
17.17.3 dp averaging
Factor for the average determination of the differential pressure.
Range:
1
… 255
17.17.4 dp offset
Use the dp offset to correct static offset of the differential pressure caused by the transmitter or
installation. The set value is subtracted from the measured value.
Range:
-10.0 mbar ...
0.0
… +10.0 mbar
17.17.5 dp1A/1B end
Maximum value (end value) of the dp transmitter at 20 mA.
Range:
1.0 mbar ... 10000.0 mbar
17.17.6 dp1A/1B input
Electrical assignment of the current input to the measured value.
Range:
I1, I2, I3, I4
17.18
Pressure
17.18.1 Air pressure
Air pressure for correcting the relative pressure sensors.
Range:
0.500 ...
1.000
… 1.200 bar
17.18.2 Pressure Q correction
Flow rate dependent pressure correction.
P
k
= P + pressure Q correction * density * Qb²
Range:
-1e37 ... +1e37
17.18.3 Pressure mode 1 ... 3
Operating mode for the pressure transmitter. The absolute pressure is corrected with –50% of the dp
for the cross probe (CP). In the Q correction setting, the pressure is corrected in a flow rate dependent
manner.
