#CMT# #/CMT# Device for determining the total pressure in a gas measuring stream of a combustion engine comprises a pressure measuring unit or a removal site (19) arranged within a back-up channel (16) through which flows a medium (17) at high speed. #CMT# : #/CMT# Preferred Features: The back-up channel is structured so that the flow speed of the medium at the pressure measuring unit or removal site lies below the speed of sound. The back-up channel has an inlet opening (20) in the direction of the medium. #CMT#USE : #/CMT# Device for determining the total pressure in a gas measuring stream of a combustion engine. #CMT#ADVANTAGE : #/CMT# The device has a simple structure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the device. 16 : Back-up channel 17 : Medium 19 : Removal site 20 : Inlet opening 24 : Base.
