4.6.3.1 Voltage sensor type
The example means: 0 mV corresponds to 0 bar, 5 V corresponds to 10 bar.
Mode
unipolar : Measuring only positive signals.
bipolar : Measuring positive and/or negative signals.
Measuring range
Select a measuring range that is equal to or greater than the signal from the
sensor or signal source to prevent A/D converter overload. The channel receives
the status ‘Measurement range overrun/underrun’ for measurements not within
the range. Channel status values are available in
status monitoring.
Scaling
Enter two points from the sensor's characteristic curve, if possible, the lower and
upper vertexes. For a linear characteristic, measurement values are then con-
verted into the unit of measurement (scaling) from the sensor. For non-linear char-
acteristics, use
Sensor compensation . Refer to tab Sensor compensation . The
specified range (in the example 0bar to 10bar) is used as the default for the
ProfiSignal graphic display area. The channel receives the status "scale range over-
run" for "scale range underrun" when not within the range. Channel status values
are available in
status monitoring.
