Abstract

"DISPOSITIVO PARA A MEDIçãO DE DISTâNCIA". A invenção se refere a um dispositivo para a medição de distância, compreendendo um elemento de transmissão (9), para a emissão de ondas acústicas ou eletromagnéticas, pulsadas. O dito elemento de transmissão está previsto em uma primeira extremidade de uma distância (L) ou a uma distância conhecida da primeira extremidade. O dispositivo contém um elemento de recepção (13), para ondas emitidas. O dito elemento de recepção (13) recebe as ditas ondas em uma segunda extremidade da distância (L) ou, após reflexão na segunda extremidade, na primeira extremidade. Uma unidade de avaliação e controle (11) calcula a distância (L) desde o tempo de programação e a velocidade de sinal. De acordo com a invenção, um tubo telescópico (3) com dois elementos de tubo (5, 7) juntos, é usado entre a primeira extremidade e a segunda extremidade. O elemento de transmissão (9) e o elemento de recepção (13), estão arrumados dentro ou junto aos elementos de tubo (5; 7) respectivamente ou são acoplados com os elementos de tubo através de condutores de onda. Um dos elementos de tubo pode ser também acoplado com um elemento movimentável que pode alterar o local.
