Example 2: Temperature and Water Pressure Measurements

Writing a data logger program

1. Proceed as in the previous example to set up the program using SCWin following steps

one and two above. Choose an appropriate name for the new program.

3. From the home page press “Sensors”. Under “Available Programs” open the “Generic

Measurements” folder. Select “Full Bridge”, the transducer is of this type of circuit,

and press the red arrow, or double click it (See Fig. 10). Set the “Range of Sensor

Voltage” to +/- 250 mv (See Fig. 11). Then click OK. The sensor should now be

listed under “Selected Sensors” on the left side of the screen. Again under available

sensors, go to temperature and select the Type T thermocouple as described previously.

After the thermocouple has been selected both sensors should be listed under “Selected

Sensors”.

4. Press the “Wiring Diagram” button at the bottom of the window as illustrated in Fig.10

and a window depicting the wiring diagram of the data logger for a pressure transducer

and Type T thermocouple appears, see Fig. 12. Connect the blue wire of the

thermocouple with the port 2H and the red wire of the thermocouple with the port 2L of

the CR10X data logger (you will need a small flathead screw driver to tighten the

thermocouple wire down).
