  • Pressure transducer magnetically-coupled interface complementing minimal diaphragm movement during operation
    Patent number: 5392653
    Abstract: A pressure measurement system includes a diaphragm and a chamber for exposing one side of the diaphragm to a fluid. A force transducer is provided for measuring force exerted by the fluid on the one side of the diaphragm independent of diaphragm position. A ferromagnetic plate is attached to the diaphragm to enable removable coupling of the diaphragm with a magnet permanently attached to the force transducer.

  • Reduced pulsation tapered ramp pump head
    Patent number: 5230614
    Abstract: A peristaltic pump includes a plurality of rollers for compressing and sealing a collapsible and resilient tube. A housing and a pump arm with a specific arcuate surface and position with respect to the housing enable the succesive contact and gradual compression of the rollers with the tube in a manner for moving a fluid through the tube in one direction without creating substantial fluid back pressure in an opposite direction.
