Patent attributes
The invention is directed to a pressure sensor device for sensing decompression in a compartment, such as an aircraft cockpit, and causing a compartment door to be free to open substantially simultaneously in response to the decompression. The pressure sensor comprises a first pressure port and a second pressure port where both pressure ports are open to the compartment, and the second pressure port has a greater flow restriction than the first pressure port, When the pressure sensor is actuated by a difference in pressure between the first pressure port and the second pressure port caused by decompression in the compartment, the pressure sensor sends a signal either via direct wired in series or to a controller to enable movement of a compartment door in response to the decompression.
