结构及作业原理:
ABB PFEA113-65 3BSE050092R65张力传感器的原理是在称重传感器的基础上，使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际和力传递部分之间并靠近压电板。张力传感器按其作业原理能够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改动而改动，改动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，从而使板黄发生位移，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酯。
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，用千丈量固体，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。
而张力传感器大都选用三轮款式的结构，为了不影响缆绳的运转所以在设计上也做到了坚固而紧凑的原理设计，丈量重复度好，精度高，装置简便是基干二轮款式的设计特色，而且中心轮的可移动性也便于装置及运转。

Structure and operating principle:

The principle of the ABB PFEA113-65 3BSE050092R65 tension sensor is based on the load cell, the use of two tension transfer components to transmit the 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 on the other side of the edge and the force transfer part between and close to the piezoelectric plate. The tension sensor can be divided into strain gauge type and micro-displacement type according to its operating principle.

Strain gauge type tension sensor is the tension strain gauge and compression strain gauge are connected together according to the bridge mode, the resistance value of the strain gauge will change with the change of the 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 yellow 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 detection ester.

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 to measure solids with thousands, most of the tension and pressure, often called the tension sensor, because it looks like an S-shape, so called the S-type tension sensor used on.

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