Control circuit for the switching motor of self-stabilizing balances

An automatic control circuit for a switching motor of an electomechanical, self-stabilizing balance having electromagnetic compensation and including an analog transducer which produces an analog measured value which is used to initiate operation of the switching motor whenever an upper or lower limiting value is exceeded and can be processed for display on a display, the control circuit comprising analog-to-digital converter circuit means coupled to said analog transducer and responsive to its output for producing high-speed coarse or preliminary information and fine information;

• computer means coupled to said analog-to-digital converter circuit means and responsive to its output for producing at least one switching signal in event at least one of the upper or lower limiting values is exceeded;
• and motor control circuit means coupled to said computer means and responsive to output thereof for producing signals to trigger said switching motor upon receipt of a switching signal from said computer means.
