Abstract
Inventia se refera la o sonda ultrason digitala destinata masurarii automate a distantei de la chila navei la fundul apei, fiind un instrument foarte util pentru navigatia în ape mici si în timpul acostarii. Sonda ultrason, conform inventiei, este alcatuita dintr-un oscilator pilotat stabil cu cuart, un divizor de frecventa, un oscilator de la care se emit semnale si care receptioneaza ecoul ce trece printr-un amplificator selectiv, un demodulator , un circuit poarta, un numarator si un bloc deafisare.The invention relates to a digital ultrasonic probe for automatic measurement of the distance from the ship's keel to the bottom of the water, being a very useful tool for small water navigation and during mooring. The ultrasonic probe according to the invention consists of a quantum stable quad oscillator, a frequency divider, a oscillator from which signals are emitted and which receives the echo through a selective amplifier, a demodulator, a gate circuit, a counting and blocking.
