摘要：

This paper compares static pressure sensors suitable for aircraft air data systems. Characteristics of selected sensors influenced by environmental effects are compared with regards to their price. A group of sensors was chosen in order to cover a wide range of sensor samples available on the market. The article compares characteristics of sensors manufactured by Freescale, the MPX series, Memscap SP82, Intersema MS5534, and samples from SensorTechnics and Honeywell. The measurement setup is also described in the article. Digital modules connected through the CAN bus and GPIB measurement instruments were used for data acquisition. The data was sampled through Matlab Data Acquisition System extended by our own CAN Aerospace Toolbox that is being developed at CTU in Prague. The article finally compares all tested sensors and presents possible calibration methods, in which temperature effects and non-linearity were taken into consideration.
