Abstract

Un tachimetro elettronico per autoveicoli possiede un trasduttore (1) di impulsi, il quale mediante esplorazione di una parte rotante con le ruote produce un numero di impulsi di misura proporzionale alla rotazione della ruota, rispettivamente dell'albero di azionamento della ruota, i quali impulsi di misura sono adducibili, quali impulsi di conteggio digitali, ad un circuito di analisi (da 2 fino a 8), il quale presenta uno stadio di adattamento (3) tenente conto dei parametri del veicolo sostanziali per la misura del percorso, rispettivamente della velocità, in particolare del diametro della ruota, rispettivamente del pneumatico, è munito di una memoria non volatile, e produce, in dipendenza del numero di impulsi di misura verificantisi nell'unità di tempo, segnali di comando per una unità (9) di indicazione della velocità. Per poter impiegare uguali tachimetri per diversi autoveicoli,
