Strain Gauge
The strain gauge is an ideal application to take advantage of
the moderate bandwidth and high accuracy of the EL5150.
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.
