Abstract
A sensor apparatus for measuring a pressure of an airflow in a duct. The sensor apparatus includes a first sensor portion that includes a first end and a second end, and that is without ports in communication with the airflow. The sensor also includes a second sensor portion that is coupled to the first sensor portion adjacent the first end, and a third sensor portion that is coupled to the first sensor portion adjacent the second end. The second sensor portion includes a first port that senses a first airflow pressure of the airflow, and a second port that senses a second airflow pressure of the airflow. The third sensor portion includes a third port that senses a third airflow pressure of the airflow, and a fourth port that senses a fourth airflow pressure of the airflow.

- a first sensor portion including a first end and a second end, the first sensor portion without ports in communication with the airflow,
- a second sensor portion coupled to the first sensor portion adjacent the first end, the second sensor portion including a first port operable to sense a first airflow pressure of the airflow, and a second port operable to sense a second airflow pressure of the airflow, and
- a third sensor portion coupled to the first sensor portion adjacent the second end of the first sensor portion, the third sensor portion including a third port operable to sense a third airflow pressure of the airflow, and a fourth port operable to sense a fourth airflow pressure of the airflow.
A sensor apparatus for measuring a pressure of an airflow in an air duct system, the sensor apparatus comprising:
- a duct defined by an upstream side and a downstream side and including a perimeter wall defining a centerline of the duct extending longitudinally through the duct;
- a first sensor defining a first axis and including a curved surface profile positioned in communication with the airflow adjacent the upstream side of the duct, the first sensor further including a substantially planar surface profile defining a back of the first sensor and disposed opposite the curved surface profile, and a first plurality of ports disposed in the curved surface profile in communication with the airflow to sense airflow pressures;
- and
- a second sensor positioned adjacent the first sensor, the second sensor defining a second axis and including a curved surface profile positioned in communication with the airflow adjacent the downstream side of the duct, the second sensor further including a substantially planar surface profile defining a back of the second sensor and disposed opposite the curved surface profile, the first sensor and the second sensor positioned adjacent each other in back-to-back relationship within the duct, the second sensor further including a second plurality of ports in communication with the airflow to sense airflow pressures.
