Design of Electrical Measurement Devices and Systems with Force Compensation
A Russian textbook n the design of aviatio instruments is discussed. It set forth problems of calculating the st tic and dynamic char cteristics of instruments from their structural diagrams, design of electrical easurement devices with conversion of current into torque and force, and torque pickups for electrical measurement systems with force compensation. The variou sections of the book give the necessary theoretical bases for the formulas, typical procedfor and design of instruments and pickups, and the design of their basic units. The book is intended for students in the instrument-building and automation departments of the higher educational institutions for aeronautics, for use as a study aid in routine and diplomate design assignments. V RIOUS S CTIONS MAY ALSO BE OF INTEREST FOR ENGINEERING-TECHNICAL WORKERS IN THE INDUSTRY. (Author).
