传感器（英文名称：transducer/sensor）是能感受到被测量的信息，并能将感受到的信息，按一定规律变换成为电信号或其他所需形式的信息输出，以满足信息的传输、处理、存储、显示、记录和控制等要求的检测装置。

传感器的存在和发展，让物体有了触觉、味觉和嗅觉等感官，让物体慢慢变得活了起来。传感器的特点包括：微型化、数字化、智能化、多功能化、系统化、网络化。它是实现自动检测和自动控制的首要环节。

ABB-216GD61a-HESG324436R3-A-HESG324428 PLC控制系统工程应用的抗干扰设计

为了系统在工业电磁环境中免受或减少内外电磁干扰，必须从设计阶段开始便采取三个方面抑制措施:抑制干扰源;切断或衰减电磁干扰的传播途径;提高装置和系统的抗干扰能力。这三点就是抑制电磁干扰的基本原则。

ABB-216GD61a-HESG324436R3-A-HESG324428PLC控制系统的抗干扰是一个系统工程，要求制造单位设计生产出具有较强抗干扰能力的产品，且有赖于使用部门在工程设计、安装施工和运行维护中予以全面考虑，并结合具有情况进行综合设计，才能系统的电磁兼容和运行可靠。进行具体工程的抗干扰设计时，应主要以下两个方面。

在选择设备时，首先要选择有较高抗干扰能力的产品，其包括了电磁兼容(EMC)，尤其是抗外部干扰能力，如采用浮地技术、隔离能好的PLC系统;其次还应了解生产厂给出的抗干扰指标，如共模拟制比、差模拟制比，耐压能力、允许在多大电场强度和多高频率的磁场强度环境中工作;另外是靠考查其在类似工作中的应用实绩。

transducer (English name: transducer/sensor) is a detection device that can feel the information being measured, and can transform the felt information into an electrical signal or other required form of information output according to a certain law to meet the requirements of information transmission, processing, storage, display, recording and control.

The existence and development of sensors, so that the object has the sense of touch, taste and smell, so that the object slowly become alive. The characteristics of the sensor include: miniaturization, digitalization, intelligence, multi-function, systematization and networking. It is the primary link to realize automatic detection and automatic control.

ABB-216GD61a-HESG324436R3-A-HESG324428 is mainly generated by the mutual electromagnetic radiation between the internal components and circuits of the system, such as the mutual radiation of the logic circuit and its impact on the analog circuit, the mutual influence of the analog and logical ground and the mutual mismatch between the components. This belongs to the PLC manufacturer's electromagnetic compatibility design content inside the system, more complex, as an application department is unable to change, not much consideration, but to choose a system with more application performance or tested.

Anti-interference design of ABB-216GD61a-HESG324436R3-A-HESG324428 PLC control system engineering application

In order to protect the system from or reduce internal and external electromagnetic interference in the industrial electromagnetic environment, three suppression measures must be taken from the design stage: suppression of interference sources; Cut off or attenuate the transmission path of electromagnetic interference; Improve the anti-interference ability of devices and systems. These three points are the basic principles of suppressing electromagnetic interference.

ABB-216GD61a-HESG324436R3-A-HESG324428PLC control system anti-interference is a system engineering, requiring manufacturing units to design and produce products with strong anti-interference ability, and depends on the use of the department in the engineering design, installation, construction and operation and maintenance to be fully considered. And combined with the situation of comprehensive design, in order to the electromagnetic compatibility and reliable operation of the system. The anti-interference design of specific projects should be mainly in the following two aspects.

In the selection of equipment, we must first choose products with high anti-interference ability, including electromagnetic compatibility (EMC), especially the ability to resist external interference, such as the use of floating technology, good isolation PLC system; Secondly, we should also understand the anti-interference indicators given by the manufacturer, such as common simulation ratio, differential simulation ratio, voltage resistance, how much electric field strength and how high frequency magnetic field strength environment is allowed to work; In addition, it is based on the examination of its application in similar work.
