ABSTRACT:
A pressure sensor is provided with an insert member that reduces the dead space of a fluid conduit used to provide fluid communication between a pressure sensitive component and a cavity within which a volume is contained. The insert member is provided with a channel formed in its outer surface so that continued fluid communication can be maintained between the fluid whose pressure is to be monitored and a pressure sensitive component disposed within the structure of the pressure sensor. The use of the insert member significantly facilitates the manufacture of the pressure sensor and reduces the need to utilize pins of excessively small cross sectional area during the molding process.
