Abstract
The present invention involves a device for detecting a condition of a flowing fluid within a vehicle having reduced sulfur ingress. The device includes a base plate having a receiving surface and a circumferential edge and a printed circuit board disposed on the receiving surface of the base plate. The device further includes a housing having peripheral side walls attaching to the receiving surface adjacent the circumferential edge to define a peripheral interface enclosing the printed circuit board within the housing. The device further includes an adhesive material disposed at the interface to adhere the housing to the base plate. The adhesive material has a predetermined thermal expansion coefficient and a predetermined elastic modulus to reduce fluid ingress through the interface and to accommodate thermal expansions of the base plate and the housing.
