Load cells come in many different shapes, sizes and capacities and are now the industry standard for all types of weighing. It could be a little mine field looking for the multi axis load cell for your application. I have listed probably the most common found today and their uses.
Single Point – Single point are the cheapest and most popular type on the market today. Because of 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 may also be used in platform scales and industrial weighing systems to offer accurate readings regardless of the positioning of the load on the platform, reducing manufacturing costs.
Canister Type – Canister type have been in existence for some time and tend to be the industry standard for most high capacity, compression applications. Canister type load cells can be used as 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 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 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 permits limited movement to enable for thermal expansion and contraction along with lift off protection. This type of cell is additionally available being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are generally present in all kinds of floor, platform and shipping scales today and offers an ideal solution for most medium capacity weighing applications. Single ended torque transducer have the ability to withstand full capacity side load with no problems making them particularly ideal for weighing systems with mixers, blenders and agitators. This sort are extremely durable but could become costly and cumbersome to mount above 10,000kg. This sort of cell can also be obtainable 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 type of load cell offers superior accuracy at high capacity weighing. This type of cell has openings at either end to enable for easy link to shackles, wire rope, D links or any other rigging. Tension link load cells give a rugged design for resistance to side loading.
Torsion Ring – Torsion ring really are a relatively new concept in design and supply an excellent low profile solution for a variety of weighing applications. Unlike standard compression load cells, which may readily have problems with off-axis loading problems, torsion rings are loaded through a centrally located annular ring. By using a central floating pin to send out load to this ring, optimum load introduction is assured and off-axis loads as much as 3 or 4 degrees may be tolerated without loss in performance. Proprietary mounting modules, which offer excellent versatility, are now 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 dzrgzs 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 – All of the above have one major flaw; these are attached to devices via cable. One of the primary issues with any weighbridge or floor scale is the possibility of damaged cables. Making use of the latest technology, wireless, compression load cell are now being made available and may 1 day become the industry standard. The suggestions above load cells are now available in wireless format, even though this technology comes at greatly increased price.
S Type – S type get their name using their shape, being the letter ‘S’. S type load cells can offer an electronic output when found in either tension or compression and provide superior side load rejection. This kind of cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends can be attached. This type are employed in crane scales, hanging scales, hoist scales and many tension applications.
