该压力计主要是在不同压力范围下,用精密稳定的压力传感器感受压力,并把压力物理信号变换为模拟电信号,利用电信号调理技术处理模拟电信号,再利用A/D变换技术把压力电信号变换为数字信号,通过接口电路,计算机采集数字信号,并利用静态特性方程式处理为数字压力 The pressure gauge is mainly in different pressure range, with precision and stability of the pressure sensor to feel the pressure, and the pressure of physical signals into analog electrical signals, the use of electrical signal conditioning technology to deal with analog electrical signals, and then use A / D conversion technology to pressure The electrical signal is transformed into a digital signal which is collected by the computer through an interface circuit and processed by the static characteristic equation into digital pressure
