Abstract
Improvements in thin film sensors are disclosed. These can be used for aircraft applications. Dielectric isolation washers can be provided between a pressure sensor and an exterior metal housing of a sensor assembly. In this manner, high voltage inputs from a lightning strike or other source that reach the sensor housing are not transmitted to the sensor. Dielectric washers, insulators, and potting compounds can thus isolate a metal thin film pressure sensor from adjacent metal components (e.g., using non-conducting insulating materials like Torlon, zirconia and nylon). Besides their high dielectric strength, these materials exhibit compressive strength and resistance to wear, creep and corrosion. Desirable thicknesses for these components are provided. The described thin film pressure sensor embodiments can attain a dielectric rating of 1500 VAC.
