Abstract:
An apparatus for detecting a pressure and a temperature in an intake tube of an internal combustion engine, comprising a temperature sensor (70), a pressure sensor (40) and an evaluation circuit, the pressure sensor (40) is secured to a carrier (20) for analyzing a measurement result of the pressure sensor with as little strain as possible, the temperature sensor (70) and the pressure sensor (40) are disposed in a common housing (10), the housing (10) includes at least a first pressure chamber (16) and a second chamber (18) separate from one another and the temperature sensor (70) is disposed in a stub (15) of the housing (10), the first pressure chamber (16) communicates with the intake tube via said stub (15) and the first pressure chamber (16) is sealed off from the environment, said carrier (20) has a first portion (21) and a second portion, said first portion (21) of the carrier (20) on which the pressure sensor (40) is secured projects into the pressure chamber (16), and the second chamber (18) serves to receive and secure the second portion of the carrier (20) which includes connection elements (23), the carrier (20) is secured at the housing (10) by first and second sealing adhesive connections (22, 28) that decouple the carrier (20) from the housing (10) without mechanical strains and sealing off the first pressure chamber (16), and the temperature sensor (70) has terminal lines (71) which are secured in the housing (10) by the first sealing adhesive connections (22).
