The Transfer Standard Accuracy Barometer is an electronic instrument that measures atmospheric pressure. The display gives continuous digital recordings of instantaneous pressure and trends. A change in pressure results in vibrations within the cylinder walls and sets up a corresponding electromagnetic field. Electromagnetic coils sense the frequency of vibration and condition and amplify the signals. State-of-the-art electronic circuits within the instruments then utilize a special (curve-fit) equation to produce pressure calculation algorithms and the result is output in the form of a digital display. The pressure is applied to the interior of a thin walled sensing cylinder made from a magnetic alloy
