Abstract

Indicatore elettrico di pressione, particolarmente per autoveicoli, in cui due contatti mobili (4, 5) portati da un braccio girevole (3) sono entrambi in contatto di strisciamento con una formazione a pettine (17) includente settori conduttivi (18) alternati a settori isolanti (19) e terminanti in un deposito di materiale resistivo (20) per fornire in uscita un valore ohmico variabile in modo direttamente proporzionale al valore della pressione rilevata. Il contatto mobile radialmente interno (5) coopera con un'area conduttrice terminale (11) per l'indicazione di un valore di pressione anomala predeterminata.(Figura unica).
