ABSTRACT:
A measuring transducer comprises at least one pair of coded revolving metric indicators (2, 2', 2"), each consisting of a metric drum (11, 11', 11", 11"') and at least one coded revolving element. The revolving coded metric indicators (2, 2', 2") are rotatable about the same shaft (9) and the coded revolving elements are each positioned out of phase ahead at an appropriate angle with respect to the preceding revolving coded element. An electronic processing (18) prevents the sending of a signal to a display device when the signal read from the coded revolving elements has a value lower than that of any signal previously sent.
