摘要
在国外利用硅压敏元件进行气压探测已经非常成熟,而且应用非常广泛。本文介绍了一款高精度气压仪,它是通过硅压敏元件输出的模拟信号,经数字转换后得到数字气压信号的仪器。该气压仪通过串口将数据发送到到上位机,上位机对数据进行处理、分析。
The technology that pressure detection by silicone pres-suresensitive element is very mature in abroad, it is used widely. This paper intruduces a precision pressure instrument, it is through the silicone pressure-sensitive components of the analog signal output, then it obtains the digital pressure signals by digital conversion. This instrument sends data to computer that processes and analyses date by serial.
