A Strain Gauge Scale is an electronic version of a scale, using a strain gauge to determine weight.
The portable strain gauge consists of a small box and 1/2 meter conductor loop in a sticky tape. This isn't calibrated for weight, but rather to measure changes in deflection. Its primary use is to measure strain on bridges or other structures while under stress and in use. The strain gauge is battery powered, capable of gathering data for one month. The user can collect the data gathered through a standard computer connection interface.
Strain gauges use a property of conductors that changing their length alters their resistance. Putting a conductor along a beam under stress will change resistance in proportion to the weight placed on it. The results from several locations can be added, making a scale capable of measuring very heavy objects. The strain gauge can be very accurate, relying upon the accuracy of currency measurements, though it is sensitive to temperature variations.
