The system proposed in the present invention is based on the multiple repetition of a pulsed signal that allows for the measurement of distances and cable lengths with millimeter precision, in ranges from decimeters to several kilometers, depending on the pulse repetition times. At both ends of the distance to be measured, there is an electronic device responsible for repeating the pulse and sending it back to the other end. This electronic device is based on a precision monostable multivibrator that, each time it receives a pulse, generates a new pulse with a preset delay, thus enabling the calculation of the measured length.
It allows measuring distances and cable lengths without contact and with millimeter precision.
