Load cells of type PFCL 301E, PFTL 301E, PFRL 101 and PFTL 101
张力单元（压头？）规格PFCL 301E, PFTL 301E, PFRL 101 and PFTL 101.
The equipment is intended for use in a wide range of manufacturing processes where a web of any kind of material, e.g. paper, plastic or textile, is transported in a machine. The only requirement is that the web is wrapped over a roll. The force on the roll is proportional to the web tension. The resulting force is transferred through the bearing housings into the load cells. The load cells create a signal is proportional to the force acting in the measuring direction of the load cells. This signal is processed and amplified in the tension electronics and can be used as an input signal for process control, presentation on a display or for registration.
该设备只用于任何幅面材料的生产过程，它是传输机械量的，例如造纸、塑料和纺织。要求幅面材料被缠绕在圆筒棍上，圆筒棍的受力与的幅面材料的张力是成比例的，这个力又被安装在轴承座的压力传感器（压头）接收，压力传感器（压头）产生一个成比例的且带有方向的信号，该信号又被张力测量装置进行放大和处理，可作为过程控制的输入信号、在显示器上显示或存储。 1.4 Safety Instructions 1.4 安全说明

触摸电子单元要小心以减少静电放电所导致的伤害。注意电路盖板上的警告标志。 1.5 The Measuring Technique Based on Pressductor Technology 1.6 建立在压力传感器（技术）上的测量技术
The operating principle of a force transducer has a great effect on how well it will perform. It also affects how stiff and vibration-free the entire load cell will be as well as its robustness and tolerance to overload. All of these factors impact on the design, operation, and maintenance of the web processing machinery.
如果使用得当，力传感器（的工作原理）可获得最佳效果，它还取决于其坚固度以及整个压力传感器（压头）在无振动时的稳定度和过载能力。
ABB’s Pressductor transducer technology produces a signal as a result of changes in an electromagnetic field when the load cell is subjected to mechanical force. It is an operating principle that has its origin in a metallurgical phenomenon according to which mechanical forces alter the ability of some steels to convey a magnetic field. Unlike other types of load cell technologies, physical movement such as compression, bending or stretching is not required for signal generation. 当一个机械力作用于ABB的 Pressductor压力传感器时，将引起传感器内部磁场会发生变化从而产生一个信号。居于冶金学现象，该机械力改变某些钢传输的磁场的能力。而对于其它类型的测压元件，无论压缩、弯曲和拉伸等物理现象都不会发生作用。
A Pressductor transducer (the sensor inside the load cell) is a simple and elegant design. Essentially, two perpendicular windings of copper wire around a steel core combine to provide a measurement signal.
放置在压头里的压力传感器是一个非常简洁的设计。实际上就是两个由铜线围绕铁心组成相互垂直的的线圈提供的信号。
An electromagnetic field is created by continuously feeding an alternating current to one of the windings. The filed is positioned in such a way that, since the windings are at right angles to each other, there is no magnetic coupling between them when the load cell is unstressed.
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）
