发动机内部压力传感器自动校准技术

Automatic calibration technology of pressure sensor in rocket engine

通过分析压力测量系统的工作原理,结合硬件设备特点,设计完成了内部压力传感器自动校准系统。在Windows XP操作系统下,采用VB6.0语言,设计了传感器通道配置与自动校准程序,通过GPIB总线,完成对程控电压源EDC522及PACIFIC 6000采集装置接口操作,实现传感器自动校准。

In combination with the characteristics of the hardware equipments, the automatic cal- ibration system of build-in pressure sensors was designed on the basis of the principle analysis of the pressure measurement system. The channel configuration module and the automatic calibration pro- gram of build-in sensors was designed under the Windows XP operation system with the VB6.0 language. The interface operation of programmable power supply EDC522 and PACIFIC 6000 type acquisition device was achieved through the GPIB bus. The automatic calibration of the pressure sensors was realized.
