1.前言在小于一个 psi(磅/英寸~2)及水柱压力范围内精确地测量及定量测试低漂移压的需求已促使传感器的制造商们重新对此测量要求进行考虑。目前,通过采用各种技术已经能够将探测到的力转换成其对应的输出信号。当寻址压力在几十到几百 psi 时,所测得的力是相当强的,因而对其进行的探测也就随之大大简化。
1. Introduction The need to accurately measure and quantitatively test low drift pressures at pressures less than one psi and water column pressures has prompted sensor manufacturers to re-consider this measurement requirement. At present, it is possible to convert the detected force into its corresponding output signal by adopting various technologies. When the addressing pressure is in the tens to hundreds of psi, the measured force is quite strong, so the detection of it will be greatly simplified.
