In aircraft ground launch test, the new ICP pulse pressure sensor is commonly used to measure pulse pressure parameters of key location surface between aircraft and the launch canister which is produced by air pulse. In view of the problems that constant-current power supply should be in accordance with the need of the sensor during working, and the output signal cannot be directly converted through most AD converters, which is easily fixed with high frequency noise, this paper mainly came up with a kind of signal adjustment circuit based on the new ICP pulse pressure sensor, meanwhile theory and methods of designing power supply, pulse pressure signal adjustment module, etc. were introduced in detail. Test results show that the design can meet 3.4mA constant-current power supply demand of the new ICP pulse pressure sensor, and its output voltage signal can be accurately adjusted to conform with the required signal scope of AD7667, which ranges from 0.366V to 2.13V. Meanwhile high frequency noise signals above 9.6 kHz and switching noise brought by elliptic high-order low-pass filter can be effectively filtered out. The signal adjustment circuit with high reliability has been successfully applied to aircraft ground launch test。
