    摘要: A pressure transducer for automobiles comprises a closed housing (3), means (9, 11, 13) for detecting the pressure in the suction pipe of an engine and converting the pressure detected into electric signals, an amplification circuit (15,17) disposed in the closed housing (3), and an air passage means (27). The air passage means (27) communicates with the atmosphere, and prevents water from penetrating therethrough into the closed housing (3). The air passage means comprises an air hole (27) formed in a member (301) defining the closed housing (3) about terminals (21) provided for leading the electric signals out of the closed housing (3).
