Model Bin as a Measuring Element of Grain Pressures
Saxena, Naresh Chandra (1979) Model Bin as a Measuring Element of Grain Pressures. Pertanika, 2 (1). pp. 5-10.
The problems of measuring grain pressures in a grain bin are analysed. The difficulties in measurements in the past are critically studied and an attempt is made to minimise them in the present set-up. The important steps in instrumentation while fabricating and their effect on the results are indicated. The model bin with strain-gages affixed is examined for the measurement of grain pressures. Its use as a proper and convenient . measuring element is evaluated. It is found that the electric resistance strain gages for measuring the horizontal and vertical strains in the wall of a cylindrical bin are useful in observing pressure changes of the grain pressures on the wall.
