  • Personal sampling pump
    Patent number: 4384825
    Abstract: A portable battery powered pump providing constant mass flow of air sample through a particular filter or vapor trap in which the pump drive motor speed is controlled by an amplifier having a reference voltage input and an inverse feedback signal related to sensed motor speed. Compensation for increased resistance to air sample flow is made by a motor current feedback signal applied to the amplifier to cause motor speed to increase with increased flow resistance.
