3500/25  Bently Nevada 开发的增强型键相模块

3500/25 是由 Bently Nevada 开发的增强型键相模块。 它是一个半高、双通道模块，用于将键相信号传送到 3500 机架中的监视器模块。当轴上的键相器标记与键相器传感器对齐时，模块使用磁性传感器或接近探头检测对齐情况，并将输入信号转换为数字键相器信号。

3500/25 功能说明

对于常规设置，3500 机械保护系统最多可以接受四个键相信号，对于配对配置，它最多可以接受八个。

旋转轴或齿轮的每转一次或每转多次事件脉冲（称为键相信号）可用于精确检测定时。

因此，3500 监控模块和外部诊断工具可以测量轴转速和矢量特性，如 1X 振动幅度和相位。

增强键相模块

增强型 3500 系统模块称为增强型键相模块。在保持与用于遗留系统的现有 Keyphasor 模块的形状、配合和功能方面的完全向下兼容性的同时，它提供了比先前设计更高的 Keyphasor 信号处理能力。修订后的 149369-01 模块完全取代了 Keyphasor 模块，PWA 125792-01。

每当三重模块化冗余 (TMR) 应用需要系统键相输入时，3500 系统应使用两个键相模块。在此设置中，模块并行运行，为机架中的其他模块提供主要和次要键相信号。

如果主键相输入信号不超过四个，则具有四个以上键相输入的系统可以使用成对排列。

3500/25 操作

配对配置需要在上/下半槽位置或两个半槽位置中的两个连续监测位置。四个 Keyphasor 模块将提供四个输出通道并接受四个主要和四个备用输入通道（每个模块一个）。

设置三个Keyphasor模块也是可行的，两个耦合的和一个非配对的。用户可以这样配置单个未配对的键相器（订购两个 2 通道或一个 1 通道和一个 2 通道选项）

隔离键相输入/输出模块

Isolated Keyphasor I/O 模块适用于许多设备同时连接到 Keyphasor 信号以及需要与其他系统（例如控制系统）隔离的情况。

尽管主要为磁性拾取器应用而设计，但只要提供外部电源，隔离式 I/O 模块就兼容 Proximitor* 应用并为其提供隔离。

该 I/O 模块的主要目标是测量轴速而不是相位。该模块可以提供相位测量，尽管与非隔离 I/O 版本相比，该 I/O 引入了更大的相移。从每轮多事件输入创建每轮一次事件信号、现场可升级固件和资产管理数据报告是增强产品功能的示例。

3500/25  Bently Nevada 开发的增强型键相模块

The 3500/25 is an enhanced bond phase module developed by Bently Nevada. It is a semi-tall, dual-channel module for transmitting key confidence numbers to the monitor module in the 3500 rack. When the key phaser mark on the shaft is aligned with the key phaser sensor, the module detects the alignment using a magnetic sensor or proximity probe and converts the input signal into a digital key phaser signal.

3500/25 Function Description

The 3500 Mechanical protection system can accept up to four key trust numbers for a regular setup and up to eight for a paired configuration.

One or multiple event pulses per revolution of a rotating shaft or gear (called key confidence signals) can be used to accurately detect timing.

As a result, the 3500 monitoring module and external diagnostic tools can measure shaft speed and vector characteristics such as 1X vibration amplitude and phase.

Enhanced bond phase module

The enhanced 3500 system module is called the Enhanced bond phase module. While maintaining full backward compatibility with existing Keyphasor modules for legacy systems in terms of shape, fit, and functionality, it provides higher Keyphasor signal processing capabilities than previous designs. The revised module 149369-01 completely replaces the Keyphasor module, PWA 125792-01.

Whenever a triple modular redundancy (TMR) application requires system key phase input, the 3500 system should use two key phase modules. In this setup, modules run in parallel, providing primary and secondary key confidence numbers to other modules in the rack.

If there are no more than four primary key phase input signals, a system with more than four key phase inputs can be arranged in pairs.

3500/25 operation

The pairing configuration requires two continuous monitoring positions in either the upper/lower half slot position or two half slot positions. The four Keyphasor modules will provide four output channels and accept four primary and four alternate input channels (one per module).

It is also possible to set up three Keyphasor modules, two coupled and one unpaired. Users can configure a single unpaired key phaser in this way (order two 2-channel or one 1-channel and one 2-channel option)

Isolate key phase input/output module

Isolated Keyphasor I/O modules are suitable for situations where many devices are connected to Keyphasor signals at the same time and where isolation from other systems, such as control systems, is required.

Although designed primarily for magnetic pickup applications, the isolated I/O module is compatible with Proximitor* applications and provides isolation as long as an external power supply is provided.

The main goal of this I/O module is to measure axis speed rather than phase. This module can provide phase measurement, although this I/O introduces a greater phase shift than the non-isolated I/O version. Creating a once-per-round event signal from multiple event inputs per round, field-upgradeable firmware, and asset management data reporting are examples of enhanced product capabilities.
