Device for measuring pressure in a fluid
First Claim
1. A device for measuring pressure in a fluid, comprising:
- a holder having a first clamping portion, a second clamping portion, and at least two pressure transducers arranged between the first and second clamping portions;
each pressure transducer having a measurement surface;
a cassette having at least two measurement chambers which can be filled with a fluid, wherein each measurement chamber is mechanically coupled to the measurement surface of a respective one of the pressure transducer by a membrane and each measurement chamber has at least two connection points for a fluid flow; and
a pressing roller with which the cassette is fixed to the holder;
wherein the cassette has two outer flanges positioned opposite each other, wherein one of the flanges engages in a clamping edge of the first clamping portion of the holder and the other flange engages in the pressing roller, wherein the pressing roller is held in a rotatable manner at the second clamping portion of the holder.

Abstract
A measurement chamber, and a device for measuring pressure in a fluid, the device including a coupling element, at least one pressure transducer and at least one measuring chamber that can be filled with a fluid. The measurement chamber is mechanically coupled to the measurement surface of the pressure transducer by a membrane. The measurement chamber has at least two connection points for a fluid flow. The at least one pressure transducer is arranged in the coupling element, and the at least one measurement chamber has two outer webs opposite each other, one of the webs engaging a clamping edge of the coupling element and the other web engaging a pressing roller. The pressing roller is rotatably supported and can be connected to the coupling unit in a force-closed manner.
