In this situation a sensor is used with only one resistor R4. This resistor is placed
between A and C.
You now have to provide the three additional resistors R1, R2, and R3 for
completion of the bridge. You do this by using the half-bridge completion as
described in the previous section and adding an additional resistor R3 between
C and D. To do this there are two options:
1 Use the standard 350 Ω resistor inside the acquisition card.
2 Provide a resistor.
In situation (1) you do not need to do anything from a hardware point of view.
In situation (2) you will need to add the resistor on the plug-in module on the
location marked QB. Refer to Figure 12.9 on page 266 for electrical/schematic
details and to for mechanical/location details.
Additional wiring: you need to add wiring for the quarter bridge completion
resistor. Depending on the selection you made, connect either pin 10 (350
Ohm) or pin 9 (user) to the bridge connection marked C in the diagram, or
directly to pin 6 (-amp in) of the connector. Refer to Figure 12.12 for connection
details.
When using a quarter bridge you need to inform the Perception software about
this.
To select quarter bridge completion in Perception
To select half bridge completion in Perception proceed as follows:
1 In Perception go to the Settings sheet.
2 In the task pane select the Bridge in the Input section.
3 Select one or more channels.
