“Sensor Tables” for conversion/linearization; if you intend to
use a linear sensor, select “none”;
Figure 193. Sensor type - Conversion settings - Sensor table - Analog
Note: If a sensor table is entered for a non-linear sensor, the fol-
lowing entries for Linear input value refer to the output val-
ues of the linearization table and not to the voltage
measured on the analog pin!
• Linear input value - entry of the minimum and maximum value
of the range within which the sensor delivers measurements;
Note: Due to its linear characteristic, a linear sensor is by default
exactly defined by only two input values, the minimum and
the maximum. The range for analog sensors is 0 - 2.5 Volts.
• Linear output value - entry of the minimum and maximum
value of the linear output range which has to correspond to
the linear input value range, in the engineering units which
have been selected;
Note: For example, in Fig. 189, the input range of 0 - 2,5 Volts cor-
responds to the output range of 0 - 120 km/h wind speed.
• Verifier - entry of the minimum and maximum value within
which valid sensor measurement results can be expected. If
the values are outside the preset thresholds, an invalid sensor
value will be notified;
• Display scale - enter the minimum and maximum value for
scaling which should to be displayed on the trend graph
“Sensor data graphic”.
Counter sensor types
The “Sensor type” window provides the following window areas
for counter sensor types:
• Common settings - for entering the common definitions of the
sensor type, especially determining its technology;
