ABSTRACT:
A dual pressure sensor using a reduced number of parts to simplify its structure and having increased ease of assembly and improved air tightness. The dual pressure sensor has an airtight container, two pressure sensor units received in the airtight container so as to be in intimate contact with each other and a substrate. The pressure sensor units has two bases, two pressure sensing diaphragm chips, and an output correction circuit. The pressure sensing diaphragm chips are secured to the bases, respectively. The bases are constructed respectively from base bodies having communication paths formed inside them and also respectively from pressure introduction sections integral with and projecting from the base bodies. The pressure introduction sections respectively project outward from insertion holes formed in the airtight container.
