136188-01 Bently 以太网I/O模块

136188-01 Bently 以太网I/O模块本特利内华达公司所生产的监测保护系统主要应用在大型旋转和往复式机械的本体振动等监测保护方面，我们的空压机和氧压机系
统中都应用了BENTLY测振系统，因为超速对透平机组而言是极其危险的情形之一，所以必须安装超速保护系统。本特利公司为此研制
了由涡流传感器及超速保护监测器组成的电子超速监测系统，它是完整的超速保护系统的一部分。我们的测振系统应用有3300和3500
两种测振，这次重点介绍23500制氧机采用的3500测振系统.
3500监测系统是当今的机器检测系统，此系统能够通过多种传感器采集数据作为一个系统，提供连续、在线监测功能，适用于机械
保护应用，它是本特利内华达采用传统框架形式的系统中功能强灵活的系统，具有其他系统所不具备的多种性能和先进功能。

3500监测系统的设计目的如下:
●每个通道的价格比以往的监测系统更低，一表多用（轴振、偏心、轴位移、加速度可以通用），减少了工厂运作成本。
体积小、重量轻，是“机电一体化”特有的产品
一台收录机大小的PLC具有相当于1.8m高的继电器控制柜的功能，一般节电50％以上。
由于PLC是工业控制的专用计算机，其结构紧密、坚固、体积小巧，并由于具备很强的抗干扰能力，使之易于装入机械设备内部，因而成为实现“机电一体化”较理想的控制设备。
由于PLC具备了以上特点，它把微计算机技术与继电器控制技术很好地融合在一起，zui新发展的PLC产品，还把直接数字控制（DDC）技术加进去，并具有监控计算机联网的功能。因而它的应用几乎覆盖了所有的工业企业，既能改造传统机械产品成为机电一体化的新一代产品，又适用于生产过程控制，实现工业生产的优质、高产、节能与降低成本。
总之，PLC技术代表了当前电气控制的世界先进水平，PLC与数控技术和工业机器人已成为机械工业自动化的三大支柱。

136188-01 Bently Ethernet I/O module Bentley Nevada Company produced monitoring and protection system is mainly used in large rotating and reciprocating machinery body vibration monitoring and protection, our air compressor and oxygen compressor system
The BENTLY vibration measurement system is applied in all systems, because overspeed is one of the most dangerous situations for turbine units, so it is necessary to install overspeed protection system. Bentley developed it for this purpose
The electronic overspeed monitoring system is composed of eddy current sensor and overspeed protection monitor, which is a part of the complete overspeed protection system. Our vibration measurement system applications are 3300 and 3500
Two kinds of vibration measurement, this time focuses on the 23500 oxygen generator used 3500 vibration measurement system.
The 3500 monitoring system is today’s machine inspection system, which is able to collect data through a variety of sensors as a system to provide continuous, online monitoring functions, suitable for machinery
Protected applications, it is a highly functional and flexible system in the traditional framework form of Bentley Nevada system, with a variety of performance and advanced features not available in other systems.
3500 monitoring system is designed for the following purposes:
● The price of each channel is lower than the previous monitoring system, and a table is multi-purpose (shaft vibration, eccentricity, shaft displacement, acceleration can be universal), reducing the factory operating costs.
Small size, light weight, is “electromechanical integration” unique products
A PLC the size of a radio recorder has the function of a 1.8m high relay control cabinet, which generally saves more than 50% of electricity.
Because PLC is a special computer for industrial control, its structure is tight, strong, small size, and because of its strong anti-interference ability, it is easy to load into the mechanical equipment, thus becoming the ideal control equipment to achieve “mechatronics”.
Because PLC has the above characteristics, it integrates microcomputer technology and relay control technology well together, the latest development of PLC products, also adds direct digital control (DDC) technology, and has the function of monitoring computer networking. Therefore, its application covers almost all industrial enterprises, which can transform traditional mechanical products into a new generation of mechatronics products, and is suitable for production process control to achieve high quality, high yield, energy saving and cost reduction of industrial production.
In short, PLC technology represents the current world advanced level of electrical control, PLC and numerical control technology and industrial robots have become the three pillars of machinery industry automation.
