什么是负载电池?

A load cell is an electro-mechanical sensor used to measure force or weight. It has a simple yet effective design which relies upon the well-known transference between an applied force, material deformation and the flow of electricity. They are incredibly versatile devices that offer accurate and robust performance across a diverse range of applications. It’s no surprise that they have become essential to many industrial and commercial processes, from automating car manufacturing to weighing your shopping at the checkout. As technology explodes forward, many new and exciting applications are emerging that also stand to benefit from using load cells. New advances in robotics, haptics and medical prostheses, to name a few, all need effective ways to measure forces and weights. New types of load cells are continuously being designed to meet the needs of this ever-changing market.

  • Technology of a load cell?

    A typical load cell consists of two parts: the main body and an attached electrical circuit. The main body is what bears the weight or force and accounts for most of the load cell’s size. Typically, it is made from high-grade steel or aluminium, which ensures mechanical reliability, and predictable and uniform strain distribution.

    The electrical circuit is housed within the load cell, tightly bonded to the main body. The circuit includes strain-gauges which are specialised parts of the circuit designed to sense the deformations of the main body.

    这些应变仪由以紧密的锯齿形图案排列的薄,导电线或箔组成。这种模式使它们对沿其长度的拉伸和压缩敏感,但在宽度上不敏感。因此,它们可以精确地定位为沿特定轴的力量。例如,剪切束负载电池的应变测量值位于与载荷轴的45度角度,以最大程度地检测到穿过载荷电池的剪切应变。

  • 负载电池如何工作

    当我们使用负载电池时,一端通常被固定在框架或底座上,而另一端则可以免费附加重量或重量元件。当力将力施加到负载电池的身体上时,它会在应变下稍微弯曲。这类似于渔夫钩住鱼时发生的事情。他用手固定杆,而鱼在另一端通过线上施加力。结果是钓鱼竿弯曲。

    发生这种情况时,变形非常微妙。由于应变规路与负载电池紧密粘合,因此它与主体一致变形。发生这种情况时,电路的电阻与导线的拉伸成比例更改。使用信号调节电子设备,我们可以产生与施加力成正比的输出信号。

  • Environmental protection

    Depending on the setting, a load cell can find itself in very different environmental conditions. Naturally, a clean room within a medical laboratory differs greatly from the underbelly of an open-cast mining truck, yet both may use different load cell types. It is therefore important that they are adequately protected from the outside environment, to ensure their lasting performance for their intended use.

    Most load cells will be potted. This means that the cavities are filled with an epoxy or resin material which fully covers the electronic components. This helps to protect the circuits from outside damage and humidity and also helps to dissipate heat.

    Some load cells feature hermetic seals for the most complete environmental protection. A fully welded seal provides an airtight and robust enclosure, standing up to the most challenging environments.

    ATEX and FM certificates are available for some load cells. These certificates indicate that it is appropriate to use in potentially explosive environments without the risk of sparks. This is ideal for activities that release flammable gases or vapours such as vehicle paint spraying or workplaces that handle fine organic dusts such as grain flour or wood.

  • 负载电池的准确性

    Different tasks require different degrees of accuracy. A medical scale that measures drug doses obviously needs to have greater resolution than an industrial scale that weighs large amounts of gravel or sand. As such, you will find different types of load cell that offer varying levels of accuracy and capacity, to accommodate these diverse applications.

    存在国际规则和协议,旨在为权衡和强制测量设备提供一些质量控制。这个想法是,这种法规将有助于促进不同司法管辖区之间的和谐,从而促进贸易和经济活动。

    Internationally, the International Organization of Legal Metrology (OIML) governs these metrological regulations, and in the USA the National Type Evaluation (NTEP) Committee does the same.

    Many commercial activities where product is sold by weight require legal-for-trade weighing equipment. This is equipment that has been certified by the relevant authorities (OIML, NTEP or national standards) for use in such applications. Typically, for commercial weighing scales, you will see them certified to a C3 class under OIML.

    Load cells with OIML or NTEP certification will be suitable for legal-for-trade applications. Sometimes they will have both OIML and NTEP certification, others might have only one, depending on the market or region being sold to.

    Outside of these certifications, load cells are labelled general purpose (GP). These are not certified but can often offer similar levels of accuracy. This is ideal in situations where legal-for-trade regulations do not apply.

  • Installation and use

    负载电池的性能取决于许多因素。其中的核心是正确的安装和对齐。人们经常说,负载电池仅与安装一样好。因此,重要的是要仔细遵循制造商的建议,以便从您的设备中获得最佳效果并确保安全和持久的使用。这些建议通常包括有关负载单元的正确安装和对齐方式的信息,适当的修复和紧固件选择,使用配件安装硬件,电子辅助和校准程序的使用。
