Abstract
An apparatus for measuring airflow in an airstream includes a generally planar panel adapted to be placed in the airstream so that air passes over opposite surfaces of the panel. The panel includes at least one slot that extends through the panel. A hot-point element is mounted on one of the panel surfaces adjacent the at least one slot. The at least one slot is configured to permit air passing over the opposite surfaces to pass through the slot and become mixed together. The hot-point element is positioned on the panel so that the mixed air passes over the hot-point element.
Claims25
An apparatus for measuring airflow m an airstream, the apparatus comprising:
- a generally planar panel adapted to be placed in the airstream so that air passes over opposite surfaces of the panel, the panel comprising at least one slot that extends through the panel;
- and
- a hot-point element mounted on one of the panel surfaces adjacent the at least one slot, the at least one slot being configured to permit air passing over the opposite surfaces to pass through the slot and become mixed together, the hot-point element being positioned on the panel so that the mixed air passes over the hot-point element.
An apparatus for measuring airflow in an airstream, the apparatus comprising:
- a generally planar panel adapted to be placed in the airstream so that air passes over opposite surfaces of the panel;
- a hot-point element mounted on one of the panel surfaces so that the airstream passes over the hot-point element;
- and
- blocking elements for deflecting particulates in the airstream from impacting the hot-point element.
A method for manufacturing an apparatus for measuring airflow in an airstream, the method comprising the steps of:
- providing a generally planar panel adapted to be placed in the airstream so that air passes over opposite surfaces of the panel, the panel comprising a printed circuit board (PCB);
- providing surface mount solder pads on one of the opposite surfaces on the PCB;
- and
- surface mounting a hot-point element on the solder pads.
