AVT2838 B

The system is a very universal device that can be used wherever a simple meter is needed. As an example application, distance measurement was invented. These types of meters are used, among others, by the police. A mechanical counting system is attached to the wheel with known circumference. The right gearbox allows you to read the distance traveled in centimeters. AVT2838 is the electronic equivalent of such a device. Includes three cascaded counters whose outputs work with LED displays. On the input there is a pulse counting system - phototransistor with an illuminator separated by a shutter with a number of openings. The shutter, which is also a measuring wheel.

The device is particularly useful everywhere where there is a need for counting
