Abstract

Secondo l'invenzione si realizza un dispositivo di sicurezza contro le fughe da gas che comprende un circuito elettronico rilevatore (A) della concentrazione del gas nell'ambiente, un circuito elettronico ricevente (B) che riceve il segnale emessa da detto circuito rilevatore e che comanda la chiusura dell'elettrovalvola di alimentazione dell'impianto del gas, dove detto dispositivo si caratterizza per il fatto che il collegamento tra il circuito (B) è realizzato tramite onde radio emesse dal circuito rilevatore (A) e ricevute dal circuito ricevente (B).
