SIMPLE DISTANCE METER - PRINTED PLATE
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
Selected parameters:
- reading from the range 0-999
- presentation of the counting result - seven-segment LED displays
- the possibility of any decimal point setting
- read reset button
- photoelectric input sensor system
- small dimensions and simplicity of the system
- battery power supply
- power supply - 9Vdc
- tile dimensions 65x42mm
- printed circuit board and documentation included
A version with a set of components for self-assembly is available
