  • Inlet sampling method and device
    Patent number: 9337006
    Abstract: An inlet apparatus is disclosed. The apparatus may include a first conduit for sampling, and a second and third conduit for directing flow throughout the inlet apparatus. Flow may be induced in two opposite directions through the second conduit, which affect the flow of gas through the first conduit for sampling. The various conduits of the apparatus may be connected to a device for inducing flow in different directions. The duration of the flow in a particular direction affects the amount of sample gas that enters a detection device.
    Type: Grant
    Filed: February 12, 2014
    Date of Patent: May 10, 2016
    Assignee: Chemring Detection Systems, Inc.
