<p>The transducer has a transducer housing (2) exposable with medium i.e. gas, pressure over an emitting- and/or receiving side (4) in an installed state. The transducer housing indirectly forms a contact area (6) with housing fixtures (3a, 3b) in the installed state. The transducer housing and the housing fixtures are indirectly pressed against one another in the contact area with small surface pressure by a pre-loading unit (14) i.e. spring washer. The indirect surface pressure caused by the pre-loading unit in the contact area is greater than 0.005 mega Pascal and is less than 10 mega Pascal.</p> |
