AIR SENSOR WITH DOWNSTREAM FACING INGRESS TO PREVENT CONDENSATION |
| 摘要 |
An air flow sensor is provided with an opening facing downstream and having a thin downstream facing edge to prevent condensation or buildup of moisture thereon. The sensor has been found to reduce entrainment of particles in a mixed phase stream. The sensor is suitable for mounting to an aircraft, and to determining air temperature and relative humidity. |

1. An air sensor for sampling air in a stream, the air sensor comprising:
a body defining an enclosed channel, the channel defining a unidirectional flow path for sampled air between an ingress and an egress; the ingress having an opening to the stream, facing downstream, and no opening to the ingress facing upstream; the egress providing a flow through the enclosed channel; a device for measuring a property of sampled air retained within the channel; and a feature for mounting the body in a fixed position with respect to the stream, wherein the opening has a peripheral edge with an average thickness of 5 mm or less. |
