3500/25 改进的键相器是一个半高度，2 通道，用来为3500 框架中的监视器提供键相位信号。此接收来自电涡流传感器或电磁式传感器的输入信号，并转换此信号为数字键相位信号，该数字信号可指示何时转轴上的键相位标记通过键相位探头。每个键相有2个输入通道，3500 机械保护系统可安装2个键相器，接收4个键相位信号。
注: 键相位信号是来自旋转轴或齿轮的每转一次或每转多次的脉冲信号，提供精确的时间测量。允许3500 监测器和外部故障诊断设备用来测量诸如1X 幅值和相位等向量参数。
每个键相器可接收2 个来自涡流传感器或电磁传感器的信号。输入信号范围为-0.8V到-21.0V(非绝缘I/O )和+5V到-11V(绝缘I/O )。内可限幅，使信号不得超过此范围。无源电磁传感器要求轴转速大于200rpm(3.3Hz)。在框架前面板上，通过同轴接头，有2 个缓冲键相位输出信号。2 个缓冲键相位输出同样可在框架背面，通过欧式接头得到。
3500/45 差胀/轴向位置监测器是一个可接收趋近式涡流传感器、旋转位置传感器
(RPT)、DC 线性可变微分变换器(DCLVDT)、AC 线性可变微分变换器(AC LVDT)和旋转电位计输入信号的4 通道监测器。测量类型和相关的传感器输入将决定需要哪种输入/输出(I/O)。 它对输入信号进行处理，并将处理后的信号和用户可编程的报设置进行比较。应用3500 框架组态软件，3500/45 可被编程去完成如下功能： • 轴向（侧向）位置 • 差胀
• 标准单斜面差胀 • 非标准单斜面差胀 • 双斜面差胀 • 补偿式差胀 • 壳胀 • 阀门位置
注: 监测器通道成对编程，每次多能完成上述的两个功能。通道1 和2 能完成一个功能，而通道3 和4 能实现另外一个(或同一个)功能。但是，只有通道3 和4 能实现壳胀监测。 3500/45 监测器的主要功能是：
1) 通过将所监测参数与设定的报点进行连续比较并驱动报，以提供机械保护功能 2) 为运行人员和维护人员提供基本的机器信息。
根据组态，每一通道可将输入信号处理为称作“比例值"的多种参数。每一个有效比例值可组态为报设置点，而任意两个有效比例值可组态为危险设置点。
