A gas turbine engine includes a liner positioned within a compressor section or a turbine section of the gas turbine engine and at least partially defining a core air flowpath through the gas turbineengine. The gas turbine engine also includes a casing at least partially enclosing the liner. Additionally, the gas turbine engine includes a pressure sensor assembly having a body, an extension member, and a pressure sensor. The pressure sensor is positioned at least partially within the body and the body is positioned at least partially on an outer side of the casing, the extension member extending from the body through a casing opening in the casing and towards a liner opening in the liner. The extension member defines a continuous sense cavity exposing the pressure sensor to the core air flowpath. 一种燃气涡轮发动机，包括衬里，该衬里定位在燃气涡轮发动机的压缩机区段或涡轮区段内并且至少部分地限定穿过燃气涡轮发动机的核心空气流动路径。燃气涡轮发动机还包括至少部分地包围衬里的壳体。另外，燃气涡轮发动机包括具有主体，延伸构件和压力传感器的压力传感器组件。压力传感器至少部分地定位在主体内，并且主体至少部分地定位在壳体的外侧，延伸构件从主体延伸穿过壳体中的壳体开口并朝向衬里中的衬里开口。延伸构件限定将压力传感器暴露于核心空气流动路径
