Abstract: A method of assembling a high pressure sensor with knurl press-fit includes a first step of providing a pressure port having a material with a first hardness and a housing having a material with a second hardness less than the first hardness. The pressure port has a mounting boss and the housing has a receptacle for receiving the mounting boss. A next step includes configuring the mounting boss of the pressure port with knurls thereon. A next step includes pressing the mounting boss of the pressure port into the receptacle of the housing along a direction of the axis such that the knurls deform the receptacle of the housing to conform about the knurls to define a semi-rigid mount.

Abstract: A high pressure sensor mounting configuration (100) includes a cylindrical pressure sensor cavity (105), an internally threaded collet (170), and a housing (160). The cylindrical pressure sensor cavity includes a convex conical open end and a first bearing surface (115). The internally threaded collet includes a second bearing surface (175) that bears on the first bearing surface when the internally threaded collet is threaded onto a pressure port (140), causing the convex conical open end (110) to bear on a concave conical mating surface of the pressure port. The housing captures the collet on the pressure sensor cavity.
