A load cell is an electronic device (a transducer) that is used to convert a force into an electrical signal. What does this mean? A load cell is a transducer which converts force into a measurable electrical output. It's a mechanical electrical component used in various industries. Applications vart from personal health care to large scale / heavy scale manufacturing industries. It is also used in automation and security systems.
There is a large array of load cells that are available today, all have different specifications and are more suited to certain jobs than others. Simply put, a load cell is a weighing machine which uses electrical input to perform their tasks. They come in different varieties and sizes depending on the use of the machine. Buyers need to know the specific type and function of a load cell before purchasing one of these handy devices. In purchasing the load cells, the main features to look out for are their range of weights, overloads, and accuracy. Some common types of load cells carried by scale companies like All Scale Shop include:
|Canister Load Cell|
Canister type load cells have been around for a long time and tend to be the industry standard for most high capacity, compression applications. Canister type load cells are used for single and multi-weighing applications. This type of cell has a button on the top and bottom side and can be used in compression only. Canister type load cells are used in tank scales, vessel weighing applications, axle weighing scales, truck weighing, vehicle scales and weighbridges. Canister type load cells offer accurate measurement even in harsh environments.
Weighing Modules (beam)
|Beam Load Cell|
A weighing module or "beam" load cell generally consists of a load cell with a mounting kit.Beam load cells generally come in single or double-ended shear beam and canister type are the industry standard. Load cell weighing modules are used in tank scales, silo weighing, vessel weighing applications, axle weighing scales, truck weighing, vehicle scales and weighbridges.
Compression Load Cells:
They are made from stainless steel which enables them to withstand harsh environments. They are ideal when you use them in truck and railway scales. Experts also recommend them for tank and silo weighing. There are other people in the gas and oil industry who use them. The cool thing is that the cells have proved very effective in these industries.
Tension: they are designed to be used in lifting, weighing and general measurements. Most of tension load cells make use of sealing compounds that are very durable. To ensure that the compounds used are exceedingly durable, the cells come with a laser welded sealing.
|Tank Load Cell|
This is a type of mechanical load cell. It has a weight range of up to an incredible 10,000,000 lb, and its accuracy to one 25/th of a percent. These types of load cells can handle enormous impacts well and they are virtually insensitive to temperature. Because they can handle impact they are usually used for tanks, bins and hoppers, and hazardous areas.
This is another type of a mechanical load cell. It has a wide weight range and a high accuracy. On the plus side they are intrinsically safe and it contains no fluids but on the downside they have a slow response rate and they need to be cleaned regular with dry air. These types of load cells are usually used in the food industry and hazardous areas.
