一 电阻真空计的基本型式是指用金属丝作敏感元件的测量低真空气体压强的仪器。它是德国人M.S.Pirani(1880～1968)提出来的,故又称“皮拉尼真空计”或“皮氏计”。1906年,Pitani发表了关于电阻真空计的第一篇文章[1]。他是用惠斯通电桥、定温原理;就是说:使丝的电阻(亦即其温度 A resistance vacuum gauge basic type refers to the use of metal wire as a sensitive component of the instrument to measure the pressure of low vacuum gas. It is the German M.S.Pirani (1880 ~ 1968) proposed, it is also known as “Pirani vacuum gauge” or “Peemeter.” In 1906, Pitani published his first article on resistance vacuum gauges [1]. He is using Wheatstone bridge, the temperature principle; that is: make the wire resistance (that is, its temperature
