Abstract
The present invention relates to a compression load cell used to monitor pressure in a diapragm cassette pumping system. A plunger is axially slidable in a linear bearing and has a first end in contact with the cassette and the second end in contact with the load cell. The force signals have a direct relationship with the pressure in the cassette.
