铁路车辆上的转速信号倍增 | 方便改装，节省新车辆的费用

铁路车辆上的许多系统都需要特定时间点的当前速度信息。其中包括制动系统和驱动系统这两个对功能安全至关重要的系统。因此，提供转速信号的转速测量设备必须可靠、精确工作。

如果需要其他系统处理速度信息，通常将额外的速度测量设备安装在车轴上。但是那里的空间有限。安装和布线都需要投入时间和金钱。凭借 P16800 和 P16000，Knick 推出了一种极其简单的解决方案。耦合输出现有转速传感器的信号，并提供给其他应用。该过程无反作用，符合 SIL 安全等级。转速编码器信号在到达控制器的途中既不会受到影响，也不会受到干扰。

P16800 转速信号转换器是用于铁路车辆改装的理想解决方案。该设备有助于快速、经济高效地落实对里程计的各种要求，例如由于欧洲标准化列车控制系统 ETCS 而产生的要求。
