Abstract:
A connecting element for connecting a transducer to a sealed fluid system, comprising at least one inlet channel, at least one outlet channel and a measuring chamber connected to said inlet channel and said outlet channel in such a way as to allow a flow to pass through said measuring chamber, the measuring chamber being formed in a housing and part of the wall of the measuring chamber being formed by a membrane which is significantly more compliant than the remaining part of the wall of the measuring chamber, wherein, in the region of the membrane, there is further provided a coupling device for the detachable mechanical coupling of the connecting element to a transducer, wherein the coupling device is part of a snap-on connection between said connecting element and said transducer, the coupling device for the mechanical coupling of the connecting element to a transducer is designed such that the connecting element can be mounted on the transducer in a direction approximately perpendicular to a plane which is defined by at least one of said inlet channels and at least one of said outlet channels.
