前几讲所述的温度、压力、流量、物位等仪表和变送器均放置在现场,所以统称现场仪表;本讲所述的显示器、记录仪表和调节器等仪表和装置,因都放在控制室内,故都叫做控制室仪表。 A few of the previous talk about the temperature, pressure, flow, level and other instruments and transmitters are placed on the scene, so collectively referred to as on-site instrumentation; this talk about the display, recording instruments and regulators and other instruments and devices, In the control room, it is called the control room instrument.
