Measurement Techniques Aims and scope

The problem presented by the limited practical application of methods and instruments for automatic monitoring of the moisture content of products of the agro-industrial complex is studied. The determination of the moisture content of the agro-industrial complex by means of the thermogravimetric method is considered. The effectiveness of weighing and selection of samples by accelerated and arbitration thermogravimetric methods is analyzed. The errors in the determination of the moisture content of products of by the thermogravimetric method are estimated. It is established that the error of the accelerated method is several times that of the error of the arbitration method. The need for an improvement in the existing thermogravimetric method of determining moisture content in terms of speed and in terms of precision is noted. The importance of selecting the optimal number of parameters of a subject of study to be determined that assures maximal measurement precision is demonstrated. The basic requirements that must be imposed on the design of instruments employed in monitoring moisture content are formulated on the basis of an analysis and estimate of the precision of the thermogravimetric method of measuring moisture content.
