Abstract
The invention relates to an apparatus comprising a measurement chamber and a resonator, which can be integrated in the measurement chamber via a quick-action closure, for the liquid sensor system and for verification and measurement of the concentration of materials, substances, particles and/or microorganisms in liquids. The invention is characterized in that the resonator is held only on its outer circumference by a thin elastomer ring, and in that at the radial distance of the external diameter of the resonator, the elastomer ring on the one hand rests on an upper sealing ring of the measurement chamber, forming a seal, and on the other hand rests on a holding ring.

36. A measurement chamber and a resonator (1) integratable into said measurement chamber by a quick-release fastener for the analysis of liquids and for the detection or measurement of the concentration of materials, substances, and/or microorganisms in liquids, which comprises:
-
a housing; a resonator (1) in contact with said liquid to be examined, the resonance frequency and/or damping of said resonator changes in response to the accumulation of the material, substance, particles, or microorganisms to be detected; an elastomeric film ring (11); a sealing ring (17) located between said measurement chamber (36) and said elastomeric film ring; said resonator includes an outside diameter and an outside circumference; and
, said resonator (1) is held and sealed proximate to said outside circumference thereof by said elastomeric film ring. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)
