Load cells come in various shapes, sizes and capacities and are now the industry standard for all sorts of weighing. It may be a slight mine field searching for the multi axis load cell for your application. I have listed probably the most common found today along with their uses.
Single Point – Single point are some of the cheapest and most popular type on the market today. Because of the price and reliability, they can be found in most kinds 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 regardless of the position of the load on the platform, reducing manufacturing costs.
Canister Type – Canister type have been around for some time and are generally 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 includes a button on the top and bottom side and may be used in compression only. Canister type load cells are employed 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 type has the ability to rock on its mountings to support any misalignment in mounting surfaces whilst still being retained, this also permits limited movement to permit for thermal expansion and contraction in addition to lift off protection. This type of cell is additionally available as being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are commonly present in all types of floor, platform and shipping scales today and supplies a perfect solution for the majority of medium capacity weighing applications. Single ended rotary torque sensor have the capacity to withstand full capacity side load without any problems making them particularly appropriate for weighing systems with mixers, blenders and agitators. This sort are really durable but may become costly and cumbersome to mount above 10,000kg. This type of cell is additionally offered in weighing module form.
Tension Link – The tension link are suitable for applications such as winching, hanging scales, crane weighing scales and lifting systems. This kind of load cell offers superior accuracy at high capacity weighing. This sort of cell has openings at either end to enable for easy link with shackles, wire rope, D links or some other rigging. Tension link load cells offer a rugged design for effectiveness against side loading.
Torsion Ring – Torsion ring really are a relatively recent concept in design and provide a great low profile solution for a wide range 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 deliver load for this ring, optimum load introduction is assured and off-axis loads up to three or four degrees could be tolerated without loss in performance. Proprietary mounting modules, which offer excellent versatility, are available for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally includes 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 are definitely the dzrgzs standard. Load cell weighing modules are employed 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 attached to devices via cable. One of the primary difficulties with any weighbridge or floor scale is the risk of damaged cables. Utilizing the most advanced technology, wireless, compression load cell are actually being made available and may one day be the industry standard. The suggestions above load cells are actually obtainable in wireless format, even if this technology comes at greatly increased price.
S Type – S type obtain their name from their shape, being the letter ‘S’. S type load cells can offer an electronic output when utilized in either tension or compression and offer superior side load rejection. This type of cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends could be attached. This kind are used in crane scales, hanging scales, hoist scales and many tension applications.
