1 测控专业英语翻译 Unit 1 Measu rement, Control and Instru mentation Instrumentation is defined as the art and science of measurement and control. Instrumentation engineers are responsible for controlling a whole system like a power plant. 译为：仪器可定义为测量和控制的艺术和科学。仪器工程师负责控制整个系统，比如一个电厂。 An instrument is a device that measures and/or regulates process variables such as flow, temperature, level, or pressure. Instruments include many varied contrivances that can be as simple as valves and transmitters, and as complex as analyzers. 译为：仪器是一种用来测量和/或调节过程变量（如流量、温度、液位或压力）的装置。仪器包括许多不同的设备，可以像阀和变送器那样简单，也可以像分析仪那样复杂。 Instruments often comprise control systems of varied processes such as refineries, factories, and vehicles. The control of processes is one of the main branches of applied instrumentation. Instrumentation can also refer to handheld devices that measure some desired variable. Diverse handheld instrumentation is common in laboratories, but can be found in the household as well. For example, a smoke detector is a common instrument found in most western homes. 译为：仪器通常由如精炼厂、工厂和车辆这些不同流程的控制系统组成。过程控制是实用仪器的主要分支之一。仪器也可以是测量某个所需变量的手持设备。多样化的手持式仪器常见于实验室，在日常生活中也可以发现。例如：烟雾探测器是西方家庭中的一种常见仪器。 Output instrumentation includes devices such as solenoids, valves, regulators, circuit breakers, and relays. These devices control a desired output variable, and provide either remote or automated control capabilities. These are often referred to as final control elements when controlled remotely or by a control system. 句中 desired output variable 意为“期望输出变量”，are ref...
