Abstract
A fluid pressure sensor package can be easily assembled to have different types of probe tubes depending upon different application environments. The sensor package includes a sealed casing accommodating a sensor chip for sensing a pressure of a fluid introduced into the casing. A probe tube extends from the casing for introducing the fluid into contact with the sensor chip. The casing has a top opening, and has a side wall formed on its interior surface with a stepped shoulder for bearing a flange at the lower end of the probe tube. The flange is sealingly bonded to the sidewall of the casing by a sealer. Since the probe tube is prepared as a separate member from the casing, the casing can be a common base for various probe tubes having fluid channels of different lengths or diameters.
