Strain Gauge
The strain gauge is an ideal application to take advantage of
the moderate bandwidth and high accuracy of the EL5152.
The operation of the circuit is very straight forward. As the
strain variable component resistor in the balanced bridge is
subjected to increasing strain its resistance changes

resulting in an imbalance in the bridge. A voltage variation
from the referenced high accuracy source is generated and
translated to the difference amplifier through the buffer
stage. This voltage difference as a function of the strain is
converted into an output voltage.
