ABB传感器PFEA111-112中英文手册(2)

连续不断的给其中一组线圈通上交流电流能产生电磁场，由于线圈的位置是相互垂直的，所以在不受力时另一组线圈是没有耦合的。

However, then the transducer is subjected to a force, as shown in the figure, the magnetic field pattern changes. A portion of the field couples with the second winding and induces an AC voltage that reflects the tension exerted by the web on the measurement roll. This voltage-a comparatively

strong transducer signal-is converted by the load cell system’s tension electronics into a system output.

当然，在压力传感器收到外力时，磁场的模式发生了变化（理解是磁路发生了变化），一部分磁场耦合到另一个线圈从而产生一个交流电压，这个交流电压就是安装在的测量棍上幅面材料的张力状态。这个电压信号-相对强的压力传感器的信号-张力测量装置转换成一个系统的输出。（如图）

Chapter 2 Installation (第2章 安装)

2.1 About this Chapter

The way you install your system has more influence on its functionality, accuracy and reliability than you might think. The more accurate the installation, the better the measurement system. By following the instructions in this chapter, you will fulfill the most important requirements for proper mechanical and electrical installation.

The equipment is a precision instrument which although intended for severe operating conditions, must be handled with care.

安装系统的方法会意想不到地影响功能、精度和可靠性。越精准的安装，系统的测量效果越好。以下章节将对机械和电器的安装提出最重要的需求。

该设备是精密仪器，必须小心处理。

2.2 Safety Instructions (安全说明)

Read and follow the safety instructions given in Chapter 1 Introduction, before starting any installation work. However, local statutory regulations, if stricter, are to take precedence.

在开始任何安装工作之前，需仔细阅读并遵守第1章的安全须知。如当地的法律法规，更严格的，要优先考虑。
