Fig. 11 Setting Range of Sensor Voltage

7. 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).

The wiring diagram labeled “Full Bridge” represents the pressure transducer. The

pressure transducer has four prongs. On the bottom of the transducer these prongs are

numbered, note that the numerals are very small. Prong one will connect to the “Excite”

wire which is then connected to port E1 of the data logger. Prong two will connect to the

“High” wire which is then connected to port 1H. Prong 3 is connected to the “Ground”

wire which is then connected to port AG. Prong 4 is connected to the “Low” wire which

is then connected to port 1L. “Shield” is the bare wire in the cable bundle and is

connected to port G. It is set up so that:

Prong 1—Red Wire—Port E1

Prong 2—White Wire—Port 1H

Prong 3—Black Wire—Port AG
