A compression sensor gasket assembly and method of construction thereof is provided. The compression sensor gasket assembly includes a gasket body having opposite sealing surfaces extending between an outer periphery and an inner periphery with the inner periphery bounding a through opening. The gasket body has a passage extending from the outer periphery through the inner periphery and a pressure sensor assembly releasably attached to the gasket body in the passage and being configured to sense pressure within the through opening. The pressure sensor assembly can be removed from the gasket body in service without having to disassemble clamped members from clamped abutment with the gasket assembly. Further, the pressure sensor assembly can be routed over a curved path extending between the outer and inner peripheries to navigate about features that may be present in the gasket body.

1. A compression sensor gasket assembly, comprising: a gasket body having opposite sealing surfaces extending between an outer periphery and an inner periphery with said inner periphery bounding a through opening, said gasket body having a passage extending from said outer periphery through said inner periphery;a pressure sensor assembly releasably attached to said gasket body in said passage and being configured to sense pressure within said through opening,wherein said passage includes a circumferentially enclosed bore portion extending between said opposite sealing surfaces, said bore portion being configured for receipt of at least a portion of said pressure sensor assembly, and at least one of a recessed channel portion extending into one of said opposite sealing surfaces and a through slot portion extending through both of said sealing surfaces for receiving another portion of said pressure sensor assembly;wherein said circumferentially enclosed bore portion extends from said inner periphery and wherein said at least one recessed channel portion and said through slot portion extend from said enclosed bore portion toward said outer periphery; andfurther including a fastening device adjacent said outer periphery, said fastening device being configured for attachment to a portion of said pressure sensor assembly. 2. The compression sensor gasket assembly of claim 1 wherein said at least one recessed channel portion and said through slot portion are curved. 3. The compression sensor gasket assembly of claim 1 wherein said fastening device is a internally threaded nut fixed to said gasket body. 4. The compression sensor gasket assembly of claim 3 wherein said pressure sensor assembly has an externally threaded portion configured for threaded attachment to said internally threaded nut. 5. The compression sensor gasket assembly of claim 1 wherein said passage includes said recessed channel portion and at least one functional layer overlying said recessed channel portion. 6. The compression sensor gasket assembly of claim 5 wherein said at least one functional layer abuts at least one of said opposite sealing surfaces and seals off said recessed channel portion. 7. The compression sensor gasket assembly of claim 6 wherein said at least one functional layer has sealing beads on opposite sides of said recessed channel portion. 8. The compression sensor gasket assembly of claim 5 wherein said passage includes said through slot portion and a pair of functional layers overlying opposite sides of said through slot portion and abutting said opposite sealing surfaces. 9. The compression sensor gasket assembly of claim 8 wherein said functional layers have sealing beads on opposite sides of said through slot portion. 10. The compression sensor gasket assembly of claim 9 wherein said sealing beads are half beads diverging away from said through slot portion. 11. A method of constructing a pressure sensor gasket for sensing pressure within a cavity of an internal combustion engine, comprising: providing a substantially flat gasket body having opposite sealing surfaces extending between an outer periphery and a through opening configured to register with a cavity in the internal combustion engine;forming a passage extending from the outer periphery of the gasket body to the through opening;disposing a pressure sensor assembly in the passage with a sensor portion of the pressure sensor assembly facing the through opening and fastening the sensor assembly to the gasket body adjacent the outer periphery; andfurther including providing an internally threaded nut fixed to the gasket body adjacent the outer periphery and an externally threaded portion on the pressure sensor assembly configured for threaded attachment to the internally threaded nut. 12. The method of claim 11 further including forming the passage having a curved portion extending between the outer periphery and the through opening. 13. The method of claim 11 further including forming the passage having a circumferentially enclosed bore portion configured for receipt of the sensor portion and having at least one of a recessed channel portion extending into one of the sealing surfaces and a through slot portion extending through both of the sealing surfaces for receiving another portion of the pressure sensor assembly. 14. A method of constructing a pressure sensor gasket for sensing pressure within a cavity of an internal combustion engine, comprising: providing a substantially flat gasket body having opposite sealing surfaces extending between an outer periphery and a through opening configured to register with a cavity in the internal combustion engine;forming a passage having a curved portion extending between the outer periphery and the through opening;disposing a pressure sensor assembly in the passage with a portion of the pressure sensor assembly winding through the curved portion;further including providing the pressure sensor assembly with a flexible, tubular guide member winding through the curved portion; andfurther including providing the flexible, tubular guide member as a coil spring. 15. The method of claim 14 further including providing the pressure sensor assembly with a pressure sensor and imparting a bias via the coil spring to maintain the pressure sensor adjacent the through opening.
