Patent ID: 7137297

Claim:
A method for coupling components of a fluid sensor assembly for a vehicle, the method comprising the steps of: providing a body portion of a fluid sensor assembly with a mating surface of a first material composition; providing a head section of the fluid sensor assembly with a mating face of a second material composition sized to mate with the body portion mating surface, the second material composition being different from the first material composition; introducing the mating surface of the body portion to the mating face of the head section to define a overlapping configuration; producing a force field by providing a first magnetic field that opposes a second magnetic field; and coupling together the mating surface and mating face of the overlapped configuration with the force field to form a fluid sensor assembly by exposing the overlapped configuration to the force field, the force field strength surpassing both mating surface and mating face material yield strength without preheating either the mating surface or mating face.
