<p>The invention pertains to measurement technology and can be used as a platform weighing device comprising independent sensors for carrying out a method of measuring mechanical forces between material objects, in particular in the form of scales. The proposed method involves situating and aligning measuring units in the space between interacting material objects, conversion of mechanical force variables to electrical signal frequency parameters, forwarding of the data from the measurement units to the control unit and mathematical processing of the data according to a predetermined algorithm. The devices for carrying out the proposed method are based on the use of capacitative sensors which convert the mechanical forces into corresponding electrical signals. The technical result thus achieved is a reduction in the absolute error of measurement of maximum mechanical force values. Also achieved is an increase in the weighing sensitivity and improved resistance to extraneous mechanical and temperature influences.</p> |
