METHOD AND DEVICE FOR MEASURING WATER CONTENT OF POWDER

摘要

A measuring head (10) has prolonged metal conductive elements (12) arranged in 1 row x n columns and held on an insulative holding member (3). The measuring head (10) has an upper surface (1a) which is a contact surface to be brought into contact with a power to be measured. On this contact surface (1a), the conductive elements (12) arranged in 1 row x n columns are exposed. The n columns of the conductive elements (12) consist of conductive elements (12) of the odd number columns connected to one another by a first wire (4a) and conductive elements (12) of the even number columns connected to one another by a second wire (4b). Accordingly, the n-column conductive elements (12) constitute 2-electrode electrode terminals having one electrode consisting of the conductive elements (12) belonging to the odd-number columns and the other electrode consisting of the conductive elements (12) belonging to the even-number columns. The powder to be measured is placed on the contact surface (1a) of the measuring head (10) and the voltage generated between the two electrodes of the measuring head (10) is measured, thereby obtaining the water content in the powder.
