  • Directional low differential pressure transducer
    Patent number: 4787251
    Abstract: A pressure differential measuring apparatus (25) wherein the direction of fluid flow (5) is determined by calculating the ratio between pressures of two discrete fluid masses (3, 4). The device includes two tandem thermal sensors (7, 6), the upstream sensor creating a thermal wake which is carried past the downstream sensor, thereby slowing the downstream sensor's nominal cooling rate. A venturi (8) is utilized to create desired flow characteristics in the region of the sensors.

  • Constant temperature anemometer having an enhanced frequency response
    Patent number: 4523462
    Abstract: A constant temperature anemometer having an enhanced frequency response. A sensor element is included within one leg of a bridge circuit with a feedback circuit being operatively connected to the bridge circuit. The bridge circuit frequency response is shaped by impedance elements connected in parallel with another leg of the bridge circuit. In a preferred embodiment, the impedance elements include serially connected resistance and capacitance elements.

  • Constant temperature anemometer
    Patent number: 4503706
    Abstract: A constant temperature anemometer wherein a bridge circuit having four legs includes a sensor in one leg and resistances in the other legs. The resistance of two of the legs is formed, at least in part, by a potentiometer which allows a simultaneous adjustment of the resistance of those legs and, accordingly, the ratio of those resistances. The potentiometer may be selectively connected within the bridge circuit or, alternatively, with other circuitry to determine the operating resistance of the sensor.
