There is a large selection of load cells that are available today, all have different specifications and are more suitable for certain jobs than others. Just how have you any idea which load cell to use for which application? This is a look at some of the different load cells which are obtainable, a brief description, and which usage they are more appropriate for.
Loadcell – DL – load cells are often described by a range of aspects which people usually wish to know such as for example its range, its overload, and its own accuracy. This compression load cell has a range of 50, 100, 150, 250, 500, 1.000, 1.500, 2.000, 3.000, 4.000, 5.000 kg. Its overload capacity is around 1000%, and its accuracy is described as Industrial 0.10%, Precision 0.05%, High Precision 0.025%. This type of load cell is shockproof this means it can handle a lot going on in its surroundings, it doesn’t affect the readings, and so they are great for tough environments such as a building site.
Hydraulic – this is the kind of mechanical load cell. It has a weight range of around 10,000,000 lb, and its own accuracy is 0.25%. These kind of load cells are designed for impact well plus they are virtually insensitive to temperature. The downside is they are expensive and are complex to use. Because they can handle impact they are usually useful for tanks, bins and hoppers, and hazardous areas.
Pneumatic – this is another type of a mechanical load cell. It has a wide weight range and a high accuracy. On the plus side they’re intrinsically safe also it contains no fluids but on the downside they have a slow response rate and they must be cleaned regular with dry air. These types of load cells are usually found in the meals industry and hazardous areas.
