Load cells come in many different 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 3 axis load cell for the application. I have listed many of the most common found today as well as their uses.
Single Point – Single point are probably the cheapest and most popular type on the market today. Due to their price and reliability, they are available in most kinds of retail scales, counting scales, medical scales, parcel scales and postal scales. This sort 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 around for some time and are generally the business standard for many high capacity, compression applications. Canister type load cells are used for single and multi-weighing applications. This sort of cell has 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 is able to rock on its mountings to accommodate any misalignment in mounting surfaces whilst still being retained, this too permits limited movement to allow for thermal expansion and contraction as well as lift off protection. This type of cell is additionally available as a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are generally found in all kinds of floor, platform and shipping scales today and provides a perfect solution for many medium capacity weighing applications. Single ended shear cells have the ability to withstand full capacity side load with no problems causing them to be particularly ideal 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 type of load cell sensor is additionally available in weighing module form.
Tension Link – The tension link are suitable for applications including winching, hanging scales, crane weighing scales and lifting systems. This type of load cell offers superior accuracy at high capacity weighing. This kind of cell has openings at either end to allow for convenient link to shackles, wire rope, D links or other rigging. Tension link load cells offer a rugged design for effectiveness against side loading.
Torsion Ring – Torsion ring really are a relatively new concept in design and offer an excellent low profile solution for an array of weighing applications. Unlike standard compression load cells, which could readily are afflicted by off-axis loading problems, torsion rings are loaded through a centrally located annular ring. Simply 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 may 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 is made up of 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 definitely 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 – All of the above have one major flaw; they may be connected to devices via cable. One of the primary difficulties with any weighbridge or floor scale is the risk of damaged cables. Using the ifegti technology, wireless, load cells are now being presented and can 1 day be the industry standard. The suggestions above load cells are obtainable in wireless format, even though this technology comes at greatly increased price.
S Type – S type get their name off their shape, being the letter ‘S’. S type load cells can provide a digital output when found in either tension or compression and offer superior side load rejection. This force transducer has two female threaded fixing points, top and bottom were eye bolts or thread rod ends could be attached. This sort are used in crane scales, hanging scales, hoist scales and many tension applications.
