BENTLY 125800-01 Keyphasor输入/输出模块(内部终端)

125800-01是Bently Nevada公司开发的Keyphasor I/O模块。它是3500/25增强型Keyphasor模块的一 部分。3500框架中的监视器模块接收来自半高的Keyphasor信号，是个双通道模块, 称为Keyphasor模块。 当轴上的键相器标记与键相器传感器对齐时，模块使用磁性拾音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。对于常规设置，3500机械保护系统最多可接受四个Keyphasor信号,对于成对配置，最多可接受八个。

125800-01功能描述

由转轴或齿轮每转一次或每转几次产生的关键相量信号可用于精确识别正时。 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振幅和相位。增强型Keyphasor模块是增强型3500系统模块。它改进了以前设计的Keyphasor信号处理能力，同时在形状、配合和功能方面保持与当前

Keyphasor模块的完全向下兼容性，以用于旧系统。

Keyphasor模块PWA 125792-01已被更新的149369-01模块完全取代。当三模冗余(TMR)应用需要系统Keyphasor输入时，3500系统应使用两个

Kevphasor模块。在这种设计中 ，这些模块同时向机架中的其他模块传送主要和次要Kevphasor信号。

125800-01 is a Keyphasor I/O module developed by Bently Nevada. It is part of the 3500/25 Enhanced Keyphasor Module. The monitor module in the 3500 rack receives a half height Keyphasor signal and is a dual channel module called the Keyphasor module. When the keyphasor markings on the shaft align with the keyphasor sensor, the module uses a magnetic pickup or proximity probe to detect alignment and convert the input signal into a digital keyphasor signal. For conventional settings, the 3500 Mechanical Protection System can accept up to four Keyphasor signals, and for paired configurations, up to eight can be accepted.

125800-01 Function Description

The key phasor signals generated by each revolution or several revolutions of the shaft or gear can be used to accurately identify timing. Therefore, the 3500 monitoring module and external diagnostic tools can measure shaft speed and vector characteristics, such as 1X amplitude and phase. The Enhanced Keyphasor Module is an enhanced 3500 system module. It improves the signal processing capability of the previously designed Keyphasor while maintaining its current shape, fit, and functionality

Complete downward compatibility of the Keyphasor module for use with legacy systems.

The Keyphasor module PWA 125792-01 has been completely replaced by the updated 149369-01 module. When the third mock examination Redundancy (TMR) applications require system Keyphasor input, the 3500 system should use two

Kevphasor module. In this design, these modules simultaneously transmit primary and secondary Kevphasor signals to other modules in the rack.
