A load cell is a mechanical electrical component and is a transducer, which is used in different industries. Some of the industries where is it used include healthcare, heavy scale manufacturing and large scale manufacturing units. Besides, it is quite useful in security systems and automation. When the load is applied, its sensing element changes its shape according to the tension, stress and compression developed. A number of types are available in the market based on strain gauge based or capacitance. Some of their applications along with the types of Donut Load Cells:
Compression load cell
This type of load cell can be described by various ranges such as 5.000, 4.000, 3.000, 2.000, 1.500, 1.000,500,250,150,100 and 50 kg. This load cell is shockproof which means that the environmental changes do not affect the accuracy. It is most suitable for building sites and any other tough environment. The overload capacity of this load cell is up to 1000%.
Hydraulic load cell
This load cell is a mechanical load cell having accuracy of .25%. It can handle the weight up to 10,000,000 lb. it is virtually insensitive to temperature. However, they are a bit more expensive than other types of load cells and difficult to use. Since, they are able to handle large weights, they are best suited for tanks, hoppers, bins and hazardous areas.
Pneumatic load cell
Another type of load cell Through Hole is pneumatic load cell which is capable of handling wide range of weights with higher accuracy as compared to hydraulic and compressor load cells. One of the major advantages of this type is its inherent safety, as it does not have any fluids. However, it responds slowly to weighing and requires maintaining its dryness. That’s why, it needs to be cleaned with the help of dry air. They are used in various food industries and the best suitable for hazardous areas.
Bending and sheer beam
This type of load cell is the best suited for least weighing capacity ranging from 5 to 500 kgs. It is quite a strong load cell as it is made up of stainless steel. It comes with a double shield cable for six-wire technique and is airtight sealed. It is used to weight hoppers, silos, tanks and other touch equipments.
Apart from the above mentioned, there are various other types of load cells available. They are also used to find out the center of gravity.
