稱重傳感器由一個(gè)彈簧元件和一個(gè)用于測(cè)量這種變形的裝置組成，該彈簧元件經(jīng)歷了由于測(cè)量的力而產(chǎn)生的彈性和線性變形。測(cè)量小變形有多種方法。目標(biāo)總是將機(jī)械參數(shù)“變形”映射到電參數(shù)“電壓”上。

如何為您的應(yīng)用程序做出正確的選擇。
彈簧元件 - 中心組件
彈簧元件的目的是吸收要測(cè)量的力并將其轉(zhuǎn)換為均勻的應(yīng)變范圍。彈簧材料的彈性特性用于間接測(cè)量力。應(yīng)變計(jì)測(cè)量彈簧元件表面的應(yīng)變。應(yīng)變計(jì)由金屬箔制成，并卷在基底上。從該金屬箔上蝕刻曲折的電阻圖案。
LOAD CELLS - 在任何情況下都是準(zhǔn)確的
稱重傳感器必須應(yīng)對(duì)大范圍的機(jī)械條件。例如，他們可能不得不適應(yīng)狹小的空間，提供特別快速的讀數(shù)，承受離軸負(fù)載，處理沖擊載荷或跟蹤頻繁的載荷變化。這就是為什么在傳感器中使用不同形狀的測(cè)量元件，每個(gè)測(cè)量元件都具有其使用領(lǐng)域的特定優(yōu)勢(shì)。
應(yīng)變計(jì) - 將力轉(zhuǎn)化為信號(hào)
使用復(fù)雜的過程將應(yīng)變計(jì)應(yīng)用于彈簧元件的表面。在爆破器中，這顯然是以zui大的精度和zui高的質(zhì)量完成的，以確保它們與彈簧元件一樣受到變形。當(dāng)應(yīng)變儀變形時(shí)，它們會(huì)改變它們的長(zhǎng)度和導(dǎo)體橫截面。兩者的效果是增加電阻。這種膨脹或壓縮以及由此產(chǎn)生的力在電阻上作為電阻的變化進(jìn)行測(cè)量。

每個(gè)測(cè)量元件的設(shè)計(jì)都涉及在傳感器上提供可以應(yīng)用應(yīng)變儀的合適位置。這個(gè)位置必須提供足夠的空間來容納應(yīng)變計(jì)，以便它們產(chǎn)生一個(gè)規(guī)定的應(yīng)變并表現(xiàn)出線性和可重復(fù)的行為。

FORCE MEASUREMENT DONE PROPERLY

BURSTER - SKILLED IN THE ART OF LOAD CELL DESIGN.

LOAD CELLS - THE WAY TO MEASURE THE MECHANICAL VECTOR QUANTITY OF FORCE (F)

Load cells consist of a spring element, which experiences elastic and linear deformation as a result of the force being measured, and a device for measuring this deformation. There are various ways of measuring small deformations. The aim is always to map the mechanical parameter “deformation” onto the electrical parameter “voltage”.

The different sensor elements and their most common designs.
How to make the right choice for your application.

SPRING ELEMENT - the central component

The purpose of the spring element is to absorb the force to be measured and convert it into a uniform strain range. The elastic properties of the spring materials are used to measure the force indirectly. Strain gauges measure the strain on the surface of the spring element. Strain gauges are made of a metal foil rolled onto a substrate. A meandering resistive pattern is etched from this metal foil.

LOAD CELLS - accurate in every situation

Load cells have to cope with a huge range of mechanical conditions. For instance they may have to fit into tight spaces, deliver exceptionally fast readings, withstand off-axis loads, deal with impact loads or track frequent load changes. This is why differently  shaped measuring elements are used in the sensors, each possessing specific  advantages for their area of use.

STRAIN GAUGES - transform force into signal

Complicated processes are used to apply strain gauges to the surface of the spring element. At burster this is obviously done with the greatest precision and maximum quality, to ensure they are subject to the same deformation as the spring element. When the strain gauges are deformed, they change their length and conductor cross-section. The effect of both is to increase the electrical resistance. This expansion or compression, and hence the force, is measured electrically as a change in resistance.

PRECISION - everything in its place

The design of every measuring element is concerned with providing on the sensor a suitable location on which the strain gauges can be applied. This location must provide enough space to accommodate the strain gauges so that they produce a strain as specified and exhibit absoluy linear and reproducible behaviour.
