SENSOR SYSTEM AND METHOD FOR SENSING IN AN ELEVATED-TEMPERATURE ENVIRONMENT, WITH PROTECTION AGAINST EXTERNAL HEATING |
摘要 |
Sensing in an elevated-temperature environment is provided using a sensor system having a sensor housing with an exterior wall with a window-support region having an outwardly facing external face, and a window through the window-support region of the exterior wall and affixed to the exterior wall. A sensor unit contained within the sensor housing receives an input signal through the window. A thermal-insulation layer is on the external face of th e window-support region of the exterior wall at a location immediately adjacen t to the window. The sensor system is operated in an environment wherein the window-support region of the exterior wall is heated to a temperature of greater than about 100 ~C in the event that no thermal-insulation layer is present. In a typical application, the sensor system is attached to an aircraft such that the external face is in a forward-facing orientation, and the aircraft is operated such that the external face is heated by aerodynami c heating.
