Load cells come in many different shapes, sizes and capacities and are now the industry standard for all sorts of weighing. It can be a bit of a mine field searching for the 3 axis load cell for your application. These are probably the most common found today along with their uses.
Single Point – Single point are some of the cheapest and a lot popular type on the market today. Due to their price and reliability, they may be found in most types of retail scales, counting scales, medical scales, parcel scales and postal scales. This type of load cell could also be used in platform scales and industrial weighing systems to supply accurate readings irrespective 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 usually the business standard for most high capacity, compression applications. Canister type load cells can be used for single and multi-weighing applications. This kind of cell features a button on the top and bottom side and can be utilized 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 type has the capacity 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 sort of cell can also be available as being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are generally seen in all sorts of floor, platform and shipping scales today and supplies a perfect solution for many medium capacity weighing applications. Single ended torque transducer have the ability to withstand full capacity side load without any problems making them particularly appropriate for weighing systems with mixers, blenders and agitators. This kind are really durable but can become costly and cumbersome to mount above 10,000kg. This type of cell can also be obtainable 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 high capacity weighing. This kind of cell has openings at either end to permit for convenient link to shackles, wire rope, D links or some other rigging. Tension link load cells give a rugged design for effectiveness against side loading.
Torsion Ring – Torsion ring really are a fairly new concept in design and supply an outstanding low profile solution for a variety of weighing applications. Unlike standard compression load cells, which can readily are afflicted by off-axis loading problems, torsion rings are loaded by way of a centrally located annular ring. By using a central floating pin to transmit load to 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, that provide excellent versatility, are actually available for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally consists of a load cell with mounting kit. Various kinds 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 – All of the above have one major flaw; they are linked to devices via cable. One of the primary issues with any weighbridge or floor scale is the possibility of damaged cables. Using the latest technology, wireless, miniature load cell are being presented and can some day become the industry standard. The above load cells are actually obtainable in wireless format, although this technology comes at greatly increased price.
S Type – S type obtain their name off their shape, being the letter ‘S’. S type load cells can offer an electronic digital output when found in either tension or compression and offer superior side load rejection. This kind of cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends may be attached. This type are utilized in crane scales, hanging scales, hoist scales and most tension applications.
