Error Principle
Other sources of systematic error include bent meter needles, the use of uncalibrated instruments, drift in instrument characteristics and poor cabling practices. Even when systematic errors due to the above factors have been reduced or eliminated, some errors remain that are inherent in the manufacture of an instrument. These are quantified by the accuracy figure quoted in the published specifications contained in the instrument data sheet.

《测控技术与仪器专业英语》张凤登-UNIT-1-电气和电子工程引言-参考译文及练习答案

UNIT 1 电气和电子工程引言参考译文1.1 电气工程引言电气和电子工业已逐渐趋于成熟,世界上的每个人,每个家庭及工业都受到它所取得成就的影响。

最明显的是电子计算机在我们生活中各种层次的广泛应用,它的速度、大小和费用使其很容易且很有效地应用于商业和个人事务中。

电子学为几乎每个家庭提供了无线电收音机、电视机、盒式录像机等供娱乐的产品。

集成电路当今已成为现代电子系统的一部分,并不断提供更小、更复杂、更精密的最终产品。

50年代初的工程师会对大量的电路装在一片集成电路上感到惊奇,而今天的工程师可能对发生于2020年的技术进步感到震惊。

由于电子系统为人们提供了很多好处,它无疑已成为越来越多产品的标准元件。

过去由机械元件完成的自动功能正在被相应的电子系统替代。

采用机械拾音传感器的唱机正被电子唱机取代。

机械式打字机正被电子打字机和计算机字处理机代替。

这仅仅是机械系统向电子系统转变的几个例子。

电子工业的发展,部分是由于它的消耗低、尺寸小、被称作超大规模集成电路的相对完整的电子系统,给人以很深影响的是,在一小型计算器中,基本上只有一片很小的集成块,这片芯片只占计算器内部空间的不到五分之一。

在这片超大规模集成电路内部还有一片更小的芯片,所有电路都在该芯片上。

一个超大规模集成电路元件包含成百上千个分离的电子元件,这些元件按不同的功能块排列。

这些功能块包括储存单元,计数电路,记忆电路,运算电路等。

一片单片的超大规模集成电路就是电子表的心脏,它取代了使用很久的模拟运动式手表。

随着电子制作技术的成熟,手表的功能也不断增加。

除了能计时外,附加的复杂电路还具有闹响功能,秒表功能,计算功能,电话号码储存和信息储存更能。

这些仅是较流行的功能。

电子装置已开始使用耗电很低的CMOS电路,从而使象手表中所使用的电路靠一小片电池能连续工作多年。

电子产品在工程中和特殊的商业产品中都得到发展。

体积小、价格低的电子元器件问世时许多新领域中电子系统的应用成为现实,这些领域包括测量仪器、机械、化学、建筑、生物医学工程等。

《测控技术与仪器专业英语》张凤登UNIT-9-操纵装置-参考译文及练习答案

UNIT 9 操纵装置参考译文:9.1 终端控制单元控制器与它所控制的过程有两个接口,一个是控制器的输入,另一个是控制器的输出。

传感器和信号调节器处理输入端。

各种类型的开关元件、执行机构、控制阀、加热器、电动马达处理输出端。

在过程控制系统中,它们是终端操作系统的基本组成部分。

开关组件。

开关是电路的连接或断开设备,开关动作可由执行器机械地实现,通过螺线管按机电方式实现,或由固态器件以电子方式实现。

在控制系统中,这三种实现开关操作方法都得到了应用。

开关组件用于打开电动马达和加热元件,感测物体的存在,调节电动马达的速度,启动气动或液压缸的电磁控制阀,以及发起顺序控制系统的动作。

顺序控制系统以规定的方式执行的一组操作。

自动洗衣机是我们熟知的顺序控制系统实例。

洗衣缸填充、衣物洗涤、洗衣缸排水、衣物漂洗和甩干完全由开关控制。

电动马达。

电动马达通常用作控制系统的操纵设备。

步进电机和伺服电机提供机器人手臂和数控机床的“肌肉”。

可调速驱动器为泵和鼓风机提供有效控制。

电动马达用于邮件分类、食品包装、塑料薄膜制造和谷物粉碎。

电加热元件。

电加热元件将电能转换成热能。

作为能量转换器,电加热器是100%有效的,所有的电能被转化为热能。

然而,一些热能散失到周围环境中,导致传递到产品的热能不到100%。

为满足不同的供热需求,电加热器的大小和形状各异。

电炉燃烧器是一个电加热元件实例。

工业加热器以下列形式表现出来:盘形、带形、条形、线形、辐射形、伸缩形、陶瓷纤维形加热器,以及各种过程加热器配件。

控制阀门。

每个关于过程控制的文本都需要有控制阀部分。

控制阀毕竟是控制系统的重要组成部分。

现在的问题是,“关于控制阀需要说些什么呢?”在大多数应用中,控制阀属于经典控制回路的终端元件(final element),它为将控制器的输出转化到过程提供必要的动力,可以是双位(开关)或比例(节流调节)过程。

在典型控制回路(传感器、控制器和阀门)的三个基本组成部分中,阀门的工作条件最苛刻,也最少被理解。
