–
The sensor has a nonlinear behaviour
–
Use characteristic curve for linearization
–
Input voltage is the ratio between pull-up resistor and thermistor
Pin
Thermistor
+5V
3 kOhm
1.
Click ‘Measurement Sources’ in the Toolbox.
2.
Expand the list of ‘I/O Channels’ by clicking on ‘+’ in the DDU 7 Project Tree.
3.
Drag the ‘Characteristic Curve’ analogue signal source from the Toolbox and drop it on
the desired analogue input channel in the DDU 7 Project Tree. A ‘Characteristic Curve
Wizard’ opens.
4.
To activate the internal pull up-resistor, check the box.
The DDU 7 pull up-resistor is used to get a 5V signal at the analogue channel of the DDU
7.
It allows you to use a push-button.
The fixed value of the internal pull up-resistor is 3010 Ohm. If using an additional external
pull up-resistor, set up the overall resistance.
5.
Click ‘Next’ when done.
The second part of the ‘Sensitivity/Offset Wizard’ opens.
