Load cells come in several shapes, sizes and capacities and are now the industry standard for all sorts of weighing. It can be a bit of a mine field looking for the right load cell for your application. We have listed many of the most common found today along with their uses.
Single Point – Single point are the cheapest and most popular type on the market today. Because of their price and reliability, they are available in most kinds of retail scales, counting scales, medical scales, parcel scales and postal scales. This type of load cell can also be used in platform scales and industrial weighing systems to offer accurate readings regardless of the positioning of the load on the platform, reducing manufacturing costs.
Canister Type – Canister type have been in existence for a long period and are generally the business standard for many high capacity, compression applications. Canister type load cells are used for Torque Measurement. This sort of cell includes a button on the top and bottom side and can be used in compression only. Canister type load cells are utilized in tank scales, vessel weighing applications, axle weighing scales, truck weighing, vehicle scales and weighbridges. Canister type load cells offer accurate weighing in harsh environments.
Double Ended Shear Beam – For medium to high capacity applications, the double ended shear beam offers several advantages over other designs. This type has the ability to rock on its mountings to support any misalignment in mounting surfaces whilst still being retained, this too permits limited movement to enable for thermal expansion and contraction along with lift off protection. This sort of cell can also be available as being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are normally present in all types of floor, platform and shipping scales today and supplies an ideal solution for the majority of medium capacity weighing applications. Single ended shear cells are able to withstand full capacity side load with no problems causing them to be particularly appropriate for weighing systems with mixers, blenders and agitators. This kind are incredibly durable but can become costly and cumbersome to mount above 10,000kg. This sort of cell can also be available in weighing module form.
Tension Link – The tension link are compatible with applications such as winching, hanging scales, crane weighing scales and lifting systems. This sort of load cell offers superior accuracy at Miniature Load Cell. This type of cell has openings at either end to permit for quick connection to shackles, wire rope, D links or some other rigging. Tension link load cells provide a rugged design for effectiveness against side loading.
Torsion Ring – Torsion ring certainly are a fairly new concept in design and offer an excellent low profile solution for a variety of weighing applications. Unlike standard compression load cells, which could readily have problems with off-axis loading problems, torsion rings are loaded via a centrally located annular ring. By using a central floating pin to send out load to this ring, optimum load introduction is assured and off-axis loads approximately three or four degrees can be tolerated without loss in performance. Proprietary mounting modules, that offer excellent versatility, are now designed for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally includes a load cell with mounting kit. Various types of now come supplied as modules but generally 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.
Wireless – The suggestions above have one major flaw; they are linked to devices via cable. One of many issues with any weighbridge or floor scale is the possibility of damaged cables. Making use of the latest technology, wireless, load cells are actually being presented and could 1 day become the industry standard. All of the above load cells are now offered in wireless format, although omqzxd technology comes at greatly increased price.
S Type – S type obtain their name off their shape, being the letter ‘S’. S type load cells provides 3 Axis Load Cell when found in either tension or compression and provide superior side load rejection. This sort of cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends may be attached. This sort are utilized in crane scales, hanging scales, hoist scales and a lot tension applications.
