What are Donut Load Cells? How is it Useful?
Some applications entail bolt force measurement, monitoring the overload post, clamping force measurements or leg mounting systems. They are usually made of carbon steel or stainless steel; however, some custom designs can include aluminum in the load cell structure. On the basis of the application, the donut load cells are available in many frame sizes, materials and configurations. As they have to wear huge compressive and tension forces, they must be made from durable materials. And due to this, donut load cells are commonly made of stainless steel or carbon steel.
Apart from this, many manufacturers offer a diverse range of standard sizes and modules like the miniature load cells. However, load cells can also be customized to fit more exceptional specifications or special applications. Normally, donut load cells are made as a circular sensor with a hole passing via the center, a sensor shaped like a donut. The frame size and the diameter of the through hole are subject to vary and many load cells can even by custom designed to adjust the off center loading.
With its exceptional design of the load cells, it is now easy to monitor the forces subject to the loads passing via the cell. For instance, a donut load cell can be used to determine the compression forces which are being applied by a tightened bolt. The threads of the bolt can easily pass through the center of the cell and can be easily screwed into a tightened bolt. When the bolt is tightened, the bolt head comes in touch with the top of the load cell and applies a compressive force which can be measured. This is a mere instance of the usage of donut load cell but these load cells can be used in many industrial applications in order to monitor and measure the essential compressive forces.
When it comes to choosing a load cell, you must always consider its features and compare it for the very features and aspects like the load cell construction and the cable entry method. If the load cell used in applications that must be worked on in the harsh environment conditions then you must also consider the protection of load cells so that to make sure they provide reliable and durable performance. Additional protection can be easily attained when you put on extra coatings of greases or paints or through the use of various plating materials. The design of the load cell should also provide protection from the materials used on a daily basis as they might come in touch with water or solvents.
