FLUID FLOWING DEVICE DECREASING FLUID INVASION

摘要

PROBLEM TO BE SOLVED: To provide a detecting device capable of detecting the state of a fluid flowing inside a vehicle in such a state that sulfur invasion is decreased.

SOLUTION: A device (10) has a base plate (12), and the base plate has a receiving surface (20), a peripheral edge section (22) and a printed circuit board (13) arranged on the receiving surface of the base plate. The device (10) further has a housing (15) provided with a peripheral sidewall (23), and the peripheral sidewall is attached to the receiving surface and adjacent the peripheral edge section in order to form a peripheral interface (24) surrounding the printed circuit board inside the housing. The device (10) further has an adhesive (18) arranged on the interface in order for the housing to adhere to the base plate. The adhesive decreases the invasion of fluid flowing through the interface and has a designated thermal expansion ratio and a designated elasticity ratio in order to adapt the thermal expansion of the base plate and the housing.
