Wireless Testing System for Blade Condition of Mixture Machine Based on Silicon Micro Sensor

Mix is a key step during the producing course of the propellant.It is very important for the mixture machine to make real-time pressure measure of blade condition.An on-line monitoring system was designed and realized,and some key technologies of system were discussed si-multaneously.This system was tested in the lab,and was utilized successfully in the factory.At last,the deficiency of the test system was analyzed,and some existed questions,especially the acquisition speed,were discussed.
