125792-01 Bentley 增强型Keyphasor

3500/25增强型Keyphasor模块是一个半高双通道模块用于向中的监视器模块提供键相器信号的模块3500架。该模块接收来自近程探头的输入信号磁性拾取并将信号转换成数字键控信号，该信号指示轴上的键相标记何时与键相传感器。3500机械保护系统可以接受正常配置最多四个键相器信号，最多八个成对配置的键相器信号。

增强型关键相量模块是一个改进的3500系统模块。它提供了与之前的设计相比，扩展了Keyphasor信号处理能力同时保持完全向下兼容的形式，配合和功能与现有的Keyphasor模块在遗留系统中使用。的Keyphasor模块，PWA 125792-01，完全被最近的149369 – 01年模块。
当三模冗余(TMR)需要系统关键相量输入时在应用中，3500系统应该采用两个Keyphasor模块。在这个配置模块并行工作，以提供主和次要的关键相量信号到机架中的其他模块。有四个以上关键相量输入的系统可以使用配对配置前提是不超过四个主要的Keyphasor输入信号。一个配对配置需要两个连续的监测位置在任何上/下或两个半槽位置。四个关键相位模块将接受四个主输入通道和4个备份输入通道，并提供4个输出通道(1每个模块)。两个成对和一个非成对的构型(三个关键相量模块总数)也是可能的。在这样的配置中，用户可以进行配置一个非配对的Keyphasor(订购两个2通道或一个1通道和一个2通道选项)
隔离键相器I/O模块是为应用程序设计的关键相量信号与多个设备并行连接，需要隔离来自其他系统，如控制系统。隔离I/O模块为专为磁性拾取应用而创建，但与和兼容只要有外部电源，将为Proximitor*应用程序提供隔离供应是提供的。注意，这个I/O模块的主要目的是测量轴转速，而不是相位。该模块可以提供相位
但是这种I/O引入的相移比非隔离I/O版本略高。图1显示了隔离的相移量I/O模块将以不同的机器速度添加。增强的产品功能包括生成每回合一次的事件信号从多事件每回合输入，现场升级固件，和资产管理数据报表。

The 3500/25 Enhanced Keyphasor module is a semi-high dual channel module used to provide the key phaser signal to the monitor module 3500. The module receives the input signal from the short-range probe magnetic pick up and converts the signal into a digital keying signal that indicates when the key phase marker on the axis is with the key phase sensor. The 3500 mechanical protection system can accept up to four key-phase signals in normal configurations and up to eight key-phase signals in paired configurations.

The Enhanced Critical phasor module is an improved 3500 system module. It offers extended Keyphasor signal processing capabilities compared to previous designs while maintaining a fully backward compatible form that fits and functions with existing Keyphasor modules for use in legacy systems. The Keyphasor module, PWA 125792-01, was completely replaced by the most recent 149369-01 module.
When three-mode redundancy (TMR) requires system critical phasor inputs in an application, the 3500 system should adopt two Keyphasor modules. This configuration module works in parallel to provide primary and secondary critical phasor signals to other modules in the rack. Systems with more than four key phasor inputs can use a paired configuration provided that there are no more than four major Keyphasor input signals. A paired configuration requires two consecutive monitoring positions at any up/down or two half-slot positions. The four critical phase modules will accept four primary input channels and four backup input channels, and provide four output channels (1 per module). Two paired and one unpaired configurations (the total number of three key phasor modules) are also possible. In such a configuration, the user can configure a non-paired Keyphasor(order two 2-channel or one 1-channel and one 2-channel option).
Isolated key phase I/O modules are designed for applications where critical phasor signals are connected in parallel with multiple devices and need to be isolated from other systems, such as control systems. Isolated I/O modules have been created specifically for magnetic pickup applications, but are compatible with and will provide isolated supplies for Proximitor* applications as long as an external power supply is available. Note that the primary purpose of this I/O module is to measure shaft speed, not phase. This module can provide phase
However, this I/O introduces a slightly higher phase shift than the non-isolated I/O version. Figure 1 shows the isolated phase-shift amount of I/O modules that will be added at different machine speeds. Enhanced product features include generating once-per-turn event signals from multi-event per-turn inputs, on-site firmware upgrades, and asset management data reports.
