PRESSURE TRANSDUCER Abstract of the Disclosure The invention concerns a pressure transducer for automobiles including a closed housing, means for detect- ing the pressure in a suction pipe of an engine and for converting the pressure detected into electric signals, an amplification circuit disposed in the closed housing, and air passages. The air passages communicate with the atmosphere, and prevent water from penetrating therethrough into the closed housing. The air passages include an air hole formed in a member defining the closed housing about terminals provided for leading the electric signals out of the closed housing. In this way, the pressure trans- ducer can be mounted directly within an automobile engine without loss of performance due to water contamination.
