Abstract

A fluid pressure transducer apparatus comprising a fluid pressure transducer mechanisms and a fluid pressure-transmitting path. The fluid pressure transducer mechanism includes a fluid pressure detection mechanism, having a detection surface of a fluid pressure, for converting a fluid pressure into an electrical signal, and a chamber, formed on the detection surface, for storing a fluid. The path includes a cylindrical member having a first port comminicating with the chamber and a plurality of second ports arranged on a surface perpendicular to an axis of the cylindrical member, and a stop cock arranged in the cylindrical member to be slidable with an inner surface of the cylindircal member. The stop cock has a path defined therein and a handle for slidably rotating the stop cock in the cylindrical member through a predetermined angle so that the path communicates the first port with only one of the plurality of second ports and no other second ports communicate with each other.
