: is the bridge excitation voltage.

Foil gauges typically have active areas of about 2-10 mm² in size. With careful installation, the correct gauge, and the correct adhesive, strains up to at least 10% can be measured.

In practice

frameAn excitation voltage is applied to input leads of the gauge network, and a voltage reading is taken from the output leads. Typical input voltages are 5 V or 12 V and typical output readings are in
