张力传感器又叫张力检测器，是一种在张力控制过程中，用来检测纱线张力大小的仪器。本质上，张力传感器也是一种称重传感器。

结构及工作原理:

ABB PFEA113-65 3BSE050092R65张力传感器的原理是在称重传感器的基础上，利用两个张力传递部件来传递力，力传感器的内部结构是固定在压电板中心区域的压电板垫片的一侧，压电基片是位于另一侧边缘和力传递部分之间并靠近压电板。张力传感器按其工作原理可以分为应变片型和微位移型，

应变片型张力传感器是张力应变片和压缩应变片按照电桥方式连接在一起，应变片的电阻值会随着外压力的变化而变化，改变值的多少取决于压力的大小。

而微位移型张力传感器是通过外力施加负载，从而使板簧产生位移，然后通过差接变压器检测出张力，由于板策的位移量极小，所以叫微位移张力检测器。

根据不同拉力的强度和尺寸，设计了不同外形的张力传感器，如S型张力传感器，板环张力传感器等。S型张力传感器是最常用的机械传感器，用干测量固体，大部分张力和压力，通常称为拉压力传感器，因为它看起来像一个S形，所以称为S型张力传感器上使用。

而张力传感器多数采用三轮样式的结构，为了不影响缆绳的运行所以在设计上也做到了坚固而紧凑的原理设计，测量重复度好，精度高，安装简便是基干二轮样式的设计特点，而且中心轮的可移动性也便干安装及运行。

ABB PFEA113-65 3BSE050092R65 Tension sensor, also known as tension detector, is an instrument used to detect the size of yarn tension during tension control. In essence, the tension sensor is also a load cell.

Structure and working principle:

The principle of the tension sensor is based on the weight sensor, the use of two tension transfer components to transmit force, the internal structure of the force sensor is fixed in the center area of the piezoelectric plate on one side of the piezoelectric plate gasket, the piezoelectric substrate is located between the other side edge and the force transfer part and close to the piezoelectric plate. Tension sensor according to its working principle can be divided into strain gauge type and micro-displacement type,

Strain gauge type tension sensor is the tension strain gauge and compression strain gauge in accordance with the bridge connected together, the resistance value of the strain gauge will change with the change of external pressure, the change value depends on the size of the pressure.

The micro-displacement tension sensor is through the external force to apply the load, so that the plate spring displacement, and then through the differential transformer to detect the tension, because the displacement of the plate is very small, so called micro-displacement tension detector.

According to the strength and size of different tension, tension sensors of different shapes are designed, such as S-type tension sensor, plate ring tension sensor, etc. The S-type tension sensor is the most commonly used mechanical sensor that uses dry to measure most of the tension and pressure in a solid, often called a tension pressure sensor because it looks like an S-shape, so it is called an S-type tension sensor used on it.

The tension sensor mostly uses a three-wheel style structure, in order not to affect the operation of the cable, so in the design also achieved a solid and compact principle design, measurement repetition is good, high accuracy, easy installation is the design characteristics of the base two-wheel style, and the mobility of the center wheel will dry installation and operation.
