Abstract
Though the pressure of bulk materials cannot be measured under a simple manometer system as in the case of fluid or gas, it has become possible to measure it by a gauge method in that owing to the development of semiconductor gauges, high-sensitivity manometers have come to be made trially. However, the disadvantage of a high-sensitivity semiconductor gauge is that it involves considerable drift and lacks a stable balance. By improving the construction of the conventional pressure cell, the authors made trially a small high-sensitivity pressure cell excellent in linearity and little in drift. By using it, one can determine in detail the pressure distribution at various points such as container bottom pressure distribution, etc.
