Load cells come in various 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 probably the most common found today as well as their uses.
Single Point – Single point are probably the cheapest and many 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 existed for a long time and tend to be the market standard for most high capacity, compression applications. Canister type load cells can be used for Rotary Torque Sensor. This kind of cell has 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 a number of advantages over other designs. This type has the ability to rock on its mountings to allow for any misalignment in mounting surfaces whilst still being retained, this permits limited movement to permit for thermal expansion and contraction in addition to lift off protection. This type of cell is also available as being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are normally present in all kinds of floor, platform and shipping scales today and provides an ideal solution for many medium capacity weighing applications. Single ended shear cells 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 kind are incredibly durable but can become costly and cumbersome to mount above 10,000kg. This type of cell is additionally 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 kind of load cell offers superior accuracy at Compression Load Cell. This kind of cell has openings at either end to allow for quick link to shackles, wire rope, D links or other rigging. Tension link load cells give a rugged design for resistance to side loading.
Torsion Ring – Torsion ring really are a fairly new concept in design and provide 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 deliver load to this ring, optimum load introduction is assured and off-axis loads approximately 3 or 4 degrees may be tolerated without loss in performance. Proprietary mounting modules, that offer excellent versatility, are readily available for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally is made up of 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 the industry 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 suggestions above have one major flaw; they may be connected to devices via cable. One of the primary issues with any weighbridge or floor scale is the risk of damaged cables. Making use of the most advanced technology, wireless, load cells are now being presented and could one day be the industry standard. All of the above load cells are obtainable in wireless format, although omqzxd technology comes at greatly increased price.
S Type – S type have their name from their shape, being the letter ‘S’. S type load cells can offer Multi Axis Load Cell when used in either tension or compression and supply 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 sort are employed in crane scales, hanging scales, hoist scales and a lot tension applications.
