Load cells come in several shapes, sizes and capacities and are now the industry standard for all types of weighing. It can be a bit of a mine field looking for the multi axis load cell for your application. I have listed probably the most common found today as well as their uses.

Single Point – Single point are probably the cheapest and a lot popular type on the market today. Because of the price and reliability, they may be found in most varieties of retail scales, counting scales, medical scales, parcel scales and postal scales. This sort of load cell may also be used in platform scales and industrial weighing systems to provide accurate readings no matter the position of the load on the platform, reducing manufacturing costs.

Canister Type – Canister type have existed for a long time and tend to be the market standard for the majority of high capacity, compression applications. Canister type load cells can be used for single and multi-weighing applications. This kind of cell includes a button on the top and bottom side and may 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 weighing in harsh environments.

Double Ended Shear Beam – For medium to high capacity applications, the double ended shear beam offers numerous advantages over other designs. This sort is able to rock on its mountings to support any misalignment in mounting surfaces whilst still being retained, this also permits limited movement to enable for thermal expansion and contraction along with lift off protection. This sort of cell is additionally available as a weighing module kit.

Single Ended Shear Beam – Single ended shear beam are generally found in all types of floor, platform and shipping scales today and offers an excellent solution for many medium capacity weighing applications. Single ended shear cells have the ability to withstand full capacity side load with no problems which makes them particularly suitable for weighing systems with mixers, blenders and agitators. This sort are extremely durable but can become costly and cumbersome to mount above 10,000kg. This sort of weight sensor is additionally offered in weighing module form.

Tension Link – The tension link are suitable for applications like winching, hanging scales, crane weighing scales and lifting systems. This sort of load cell offers superior accuracy at high capacity weighing. This sort of cell has openings at either end to permit for convenient connection to shackles, wire rope, D links or other rigging. Tension link load cells provide a rugged design for potential to deal with side loading.

Torsion Ring – Torsion ring are a relatively new concept in design and supply an outstanding low profile solution for an array of weighing applications. Unlike standard compression load cells, which can readily have problems with off-axis loading problems, torsion rings are loaded by way of a centrally located annular ring. 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 could be tolerated without loss in performance. Proprietary mounting modules, which offer excellent versatility, are actually designed for both process weighing applications and platform scales.

Weighing Modules – Weighing module generally consists of a load cell with mounting kit. Many types of now come supplied as modules but generally single or double ended shear beam and canister type would be 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 above have one major flaw; they are linked to devices via cable. One of the main issues with any weighbridge or floor scale is the risk of damaged cables. Utilizing the ifegti technology, wireless, load cells are being presented and could some day be the industry standard. The suggestions above load cells are obtainable in wireless format, even if this technology comes at greatly increased price.

S Type – S type have their name off their shape, being the letter ‘S’. S type load cells can offer an electronic output when used in either tension or compression and supply superior side load rejection. This force transducer has two female threaded fixing points, top and bottom were eye bolts or thread rod ends may be attached. This kind are utilized in crane scales, hanging scales, hoist scales and most tension applications.
