A quarter bridge can consist of a single strain gauge resistor,
whose nominal value can be 120 or 350 .
For quarter bridge measurement, only 5 V can be set as the
bridge supply.
The quarter bridge has 3 terminals to connect. Refer to the
description of the full bridge for comments on the Sense lead.
However, with the quarter bridge, the Sense lead is connected to
+in(A) and sense(F) jointly.
If the sensor supply is equipped with the option “±15 V”, a
quarter bridge measurement is not possible. The pin I_1/4B for
the quarter bridge completion is used for–15 V instead.
By default there is an internal 120 completion resistor for bridge measurement. A 350 completion
resistor for quarter bridge measurement is possible as an alternative. When using this option, the scope
of available function is limited:
No direct current measurement is possible with the included connector ACC/DSUB(M)-UNI2, but it is
possible only with the special shunt connector with a 50 shunt resistor (differential measurement).
