摘要:
The analog display device comprises at least one needle driven through a gear wheel by a stepping motor, a control circuit for the motor, bidirectional counter locked with the position of the needle on a dial, the logic states of the outputs of the counter being representative of the position of the needle on the dial and a comparator for the informations delivered by the counter and the informations corresponding to the value of the function to display, the comparator acting at least indirectly on the control circuit and on the counter so that the position of the needle is representative of the value of the function to display. The device does not require any digital-analog converter nor galvanometer and it allows for, example, to display simultaneously with at least two needles the value of at least two different functions, to make changes of scale, and so on. The device may also be combined with another type of analog or digital display.
