本特利前置器330180-51-00属于bently3300XL 5m系统，灵敏度为7.87 mV/μm(200 mV/mil)，配套bently 3300 XL系列探头和电缆，接收非接触式3300系列或3300 XL电涡流探头和延伸电缆的信号，传送至本特利bently3500模块、2300/20、1900/65等振动监测器产品。导轨安装。330180-51-00前置器抗无线电干扰能力强，即使安装在玻璃纤维防护罩中，也不会受到附近无线电信号的干扰。3300 XL的端子带不需要特殊的安装工具即可紧固。由于不需要螺丝紧固，不会发生松动，所以连线更坚固。

电源要求：无安全栅时要求-17.5Vdc至-26Vdc，电流最大为12mA，有安全栅时要求－23V dc至－26Vdc；前置器材料：A 308铝；前置器重量:255 g；前置器温度：使用温度：-35°C至+85°C主要用于轴振动测量；轴向位移测量；转速计和零转速测量。本特利330180-50-00用以监测下列大中型旋转机械：汽轮机、水轮机、风机、压缩机、空分机、涡轮膨胀机、电动机和发电机、励磁机、齿轮箱、水泵等的振动监测。广泛应用于发电厂、化工厂、炼油厂、钢铁厂、机械厂、水泵厂、风机厂、高校科研单位以及自化仪表成套企业。

DCS的控制器主要是由CPU、ROM、RAM、E2PROM、地址设定开关等组成。CPU完成运算，ROM用来存操作系统、功能块库，功能块在ROM中的排列是确定的，用户是不能改变的。RAM用来存CPU的运算结果和I/O信号。E2PROM存用功能块连成的控制方案。下电时，控制方案是不会丢失的。不仅如此，控制方案不合适，还可以修改。修改采用紫外线照射，抹去E2PROM中的内容。控制器在网络中应该有地址，由这些地址开关来设定。功能块在ROM中的排列有的DCS称这种排列为功能码。码的次序就是功能块在库中的地址。各种厂家的DCS对运算算法的处理有些差异，所以名称也不一样。如有的DCS称这些算法为内部仪表，但其实质都是一段程序，本质是一样的。、在运用这些功能块时，应该标明该功能块输入输出之间运算的关系，还有运算所需要的许多参数。在用户根据被控对象，确定控制策略形成控制方案时，在功能块库中选择控制用所需要的功能块，弄清各功能块之间的联接关系，并首先定义它在E2PROM中的地址，和其它功能块的联系也都是用地址来表示的。同时填入所需参数。这些工作称为组态，这是为了区别于用语言编程。组态时，可以用作图的方式，即CAD方式。作CAD有一个软件，可以画出每一个控制回路所需的功能块以及它们之间的连接关系。

The Bentley preprocessor 330180-51-00 is a Bentley 3300XL 5m system with a sensitivity of 7.87mV /μm(200 mV/mil), equipped with a bently3300XL series probe and cable, Receive signals from the non-contact 3300 Series or 3300 XL eddy current probe and extension cable to the Bentley bently3500 module, 2300/20, 1900/65 and other vibration monitor products. Rail mounting. The 330180-51-00 preprocessor is resistant to radio interference and will not be interfered by nearby radio signals even if it is installed in a glass fiber shield. The terminal band of the 3300 XL can be fastened without special installation tools. Because no screws are needed to tighten, no loosening will occur, so the connection is stronger.

Power requirements: no safety grid requirements -17.5Vdc to -26Vdc, the maximum current is 12mA, with safety grid requirements -23V dc to -26Vdc; Pre-supply material: A308 aluminum; Preloader weight :255 g; Preprocessor temperature: Operating temperature: -35°C to +85°C mainly used for shaft vibration measurement; Axial displacement measurement; Tachometer and zero speed measurement. Bentley 330180-50-00 is used to monitor the vibration of the following large and medium-sized rotating machinery: steam turbine, turbine, fan, compressor, air engine, turbine expander, electric motor and generator, exciter, gear box, water pump, etc. It is widely used in power plants, chemical plants, oil refineries, iron and steel plants, machinery plants, pump plants, wind turbine factories, scientific research institutions in universities and complete sets of self-chemical instruments.

DCS controller is mainly composed of CPU, ROM, RAM, E2PROM, address setting switch and so on. The CPU completes the operation, the ROM is used to store the operating system, the function block library, the function block in the ROM arrangement is determined, the user can not change. RAM is used to store CPU calculation results and I/O signals. Control scheme of E2PROM storage function block. The control scheme is not lost during power-off. Not only that, the control scheme is not suitable and can be modified. Modified to use ultraviolet radiation to erase the contents of E2PROM. The controller should have addresses in the network, which are set by these address switches. Some DCS call this arrangement function code. The code order is the address of the function block in the library. The DCS of various manufacturers have some differences in the processing of the algorithm, so the name is not the same. Such as some DCS call these algorithms internal instruments, but their essence is a program, the essence is the same. When using these function blocks, the relationship between the input and output of the function block should be marked, as well as many parameters required for the operation. When the user determines the control strategy to form the control scheme according to the controlled object, the required function blocks are selected in the function block library, the connection relationship between the function blocks is made clear, and the address in E2PROM is defined first, and the contact with other function blocks is also represented by the address. Fill in the required parameters. These tasks are called configurations to distinguish them from programming in a language. Configuration, you can use the way of drawing, that is, the CAD way. CAD has a software that can draw the functional blocks required for each control loop and the connections between them.
