張力傳感器又叫張力檢測器，是一種在張力控制過程中，用來檢測紗線張力大小的儀器。本質(zhì)上，張力傳感器也是一種稱重傳感器。

結(jié)構(gòu)及工作原理:
張力傳感器的原理是在稱重傳感器的基礎(chǔ)上，利用兩個(gè)張力傳遞部件來傳遞力，力傳感器的內(nèi)部結(jié)構(gòu)是固定在壓電板中心區(qū)域的壓電板墊片的一側(cè)，壓電基片是位于另一側(cè)邊緣和力傳遞部分之間并靠近壓電板張力傳感器按其工作原理可以分為應(yīng)變片型和微位移型。應(yīng)變片型張力傳感器是張力應(yīng)變片和壓縮應(yīng)變片按照電橋方式連接在一起。應(yīng)變片的電阻值會隨著外壓力的變化而變化，改變值的多少取決于壓力的大小。
而微位移型張力傳感器是通過外力施加負(fù)載，從而使板簧產(chǎn)生位移，然后通過差接變壓器檢測出張力，由于板簧的位移量極小，所以叫微位移張力檢測器。
根據(jù)不同拉力的強(qiáng)度和尺寸，設(shè)計(jì)了不同外形的張力傳感器，如S型張力傳感器，板環(huán)張力傳感器等。S型張力傳感器是最常用的機(jī)械傳感器，用于測量固體，大部分張力和壓力，通常稱為拉壓力傳感器，因?yàn)樗雌饋硐褚粋€(gè)S形，所以稱為S型張力傳感器上使用。
而張力傳感器多數(shù)采用三輪樣式的結(jié)構(gòu)，為了不影響纜繩的運(yùn)行所以在設(shè)計(jì)上也做到了堅(jiān)固而緊湊的原理設(shè)計(jì)，測量重復(fù)度好，精度高，安裝簡便是基于三輪樣式的設(shè)計(jì)特點(diǎn)。而且中心輪的可移動性也便于安裝及運(yùn)行

Tension sensor, also known as tension detector, is an instrument used to detect yarn tension in the process of tension control. In essence, the tension sensor is also a load cell.

Structure and working principle:
The principle of tension sensor is based on the weighing sensor, the use of two tension transfer components to transfer 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, 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. The strain gauge type tension sensor is a tension gauge and a compression strain gauge connected together in a bridge mode. The resistance value of the strain gauge will change with the change of external pressure, and the amount of 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 spring displacement, and then through the differential transformer to detect the tension, because the displacement of the spring 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 for measuring solids, most of the tension and pressure, often called a tension 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 the structure of the three-wheel style, 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 accuracy, easy installation is based on the design characteristics of the three-wheel style. And the mobility of the center wheel is also easy to install and run.
