ABSTRACT:
A flow-through cell for extra-corporeal measurement of blood parameters has a pressure sensor arranged in a measurement chamber. The pressure sensor has an active pressure sensor part and an inactive pressure sensor part. The inactive pressure sensor part is constructed identically to the active pressure sensor part, and is insulated from the pressure prevailing in the measurement chamber by a rigid covering. The active and inactive sensor parts produce respective electrical signals which are subject to the same disturbing influences, so that by subtracting the signal of the inactive sensor part from the signal of the active sensor part, a measured value free of disturbing influences is obtained.
