Load cells come in several shapes, sizes and capacities and are now the industry standard for all types of weighing. It could be a slight mine field trying to find the multi axis force sensor for your application. I have listed probably the most common found today and 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 can be found in most types 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 no matter the position of the load on the platform, reducing manufacturing costs.
Canister Type – Canister type have been around for a long time and are usually the market standard for the majority of high capacity, compression applications. Canister type load cells are used for single and multi-weighing applications. This sort of cell includes a button on the top and bottom side and may be used 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 a number of advantages over other designs. This sort is able to rock on its mountings to accommodate any misalignment in mounting surfaces whilst still being retained, this permits limited movement to allow 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 commonly present in all kinds of floor, platform and shipping scales today and supplies a perfect solution for many medium capacity weighing applications. Single ended torque sensor are able to withstand full capacity side load without any problems which makes them particularly ideal for weighing systems with mixers, blenders and agitators. This type are incredibly durable but may become costly and cumbersome to mount above 10,000kg. This kind of cell is also available in weighing module form.
Tension Link – The tension link are compatible with applications including 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 with shackles, wire rope, D links or any other rigging. Tension link load cells give a rugged design for effectiveness against side loading.
Torsion Ring – Torsion ring certainly are a fairly new concept in design and offer an excellent 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. Using a central floating pin to transmit load to this ring, optimum load introduction is assured and off-axis loads approximately three or four degrees could be tolerated without loss in performance. Proprietary mounting modules, which offer excellent versatility, are now designed for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally includes a 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 – The suggestions above have one major flaw; these are attached to devices via cable. One of the main issues with any weighbridge or floor scale is the possibility of damaged cables. Making use of the most advanced technology, wireless, compression load cell are being provided and can 1 day become the industry standard. The suggestions above load cells are actually obtainable in wireless format, even though this technology comes at greatly increased price.
S Type – S type obtain their name using their shape, being the letter ‘S’. S type load cells can offer a digital output 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 could be attached. This kind are utilized in crane scales, hanging scales, hoist scales and most tension applications.
