  • Hot wire anemometer
    Patent number: 4604895
    Abstract: An electronic anemometer for measuring air mass flow in a conduit having a straight length of temperature-dependent resistive wire; a circuit board for holding at least a portion of the electronic circuitry used when the anemometer is operating to maintain the wire at a substantially constant temperature and generate an air mass flow-indicating signal based upon the air mass flow in the conduit sampled by the wire, the circuit board being mountable on the exterior of the conduit; a rigid support plate having a pair of spaced-apart openings, the plate being fixedly attached to the circuit board; a pair of electrically nonconductive support inserts, each of the inserts being fixedly retained within one of the openings in the support plate; and a pair of electrically conductive, resilient posts capable of withstanding the elevated operating temperatures encountered when the anemometer is operating, each of the posts having a wire-supporting end portion fixedly connected to the wire, the end portions being spaced
    Type: Grant
