2.3.2 Half-Bridge Input Signal Connection
For half-bridge input, two of the four bridge arms are external sensing elements,
hence the name. The other two arms are provided, or completed, by device's internal
resistors. This configuration is also called half-bridge completion.
Figure 2.6 shows half-bridge input without remote sensing signal connection. Con-
nect one end of the strain gauge sensor (R
B1
) to EX+ terminal, and the other end
(R
B2
) to both EX- and SC- terminals using different wires. In addition, connect the
middle node (junction of R
B1
and R
B2
) of the strain gauge sensor to both AI+ and
QTR/SC+ terminals using different wires. Since remote sensing is not used in this
configuration, simply connect RS+ and RS- terminals to EX+ and EX- terminals,
respectively.
