Abstract

Il trovato si inserisce nel campo dei procedimenti e dei dispositivi per la misurazione di pressioni inferiori a quella atmosferica o per misurare il grado di vuoto in un certo ambiente (2).Il procedimento si basa sull'immissione nell'ambiente di un segnale costituito da un'onda con frequenza costante, preferibilmente ultrasonica, e sul rilevamento a breve distanza di tale segnale, che risulta funzione della pressione dell'ambiente.Il vacuometro (1) consta di un circuito stampato (5) coperto ermeticamente da un cupolino (6) all'interno del quale trovano posto un trasmettitore (7) ed un ricevitore (8). Dal vacuometro (1) si diparte un condotto (4) di collegamento all'ambinete (2) del quale occorre misurare la pressione o il grado di vuoto.The invention is part of the field of processes and devices for measuring pressures lower than atmospheric or for measuring the degree of vacuum in a certain environment (2). The method is based on the introduction into the environment of a signal consisting of a wave with a constant frequency, preferably ultrasonic, and on the detection at a short distance of this signal, which is a function of the ambient pressure. The vacuum gauge (1) consists of a printed circuit (5) hermetically covered by a windshield (6) inside which there is a transmitter (7) and a receiver (8). From the vacuum gauge (1) there is a conduit (4) for connection to the chamber (2) whose pressure or vacuum level must be measured.
