Load cells come in various shapes, sizes and capacities and are now the industry standard for all sorts of weighing. It could be a little mine field trying to find the multi axis load cell for your application. These are 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 can be found in most types of retail scales, counting scales, medical scales, parcel scales and postal scales. This type of load cell can also be used in platform scales and industrial weighing systems to offer 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 usually the market standard for many high capacity, compression applications. Canister type load cells can be used as single and multi-weighing applications. This sort of cell features a button on the top and bottom side and can 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 several advantages over other designs. This kind has the capacity to rock on its mountings to support any misalignment in mounting surfaces whilst still being retained, this too permits limited movement to permit for thermal expansion and contraction in addition to lift off protection. This sort of cell is also available as a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are commonly found in all types of floor, platform and shipping scales today and offers an ideal solution for most medium capacity weighing applications. Single ended torque sensor have the capacity to withstand full capacity side load with no problems causing them to be particularly appropriate for weighing systems with mixers, blenders and agitators. This type are really durable but may become costly and cumbersome to mount above 10,000kg. This sort of cell can also be offered 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 high capacity weighing. This sort of cell has openings at either end to allow for easy link with shackles, wire rope, D links or some other rigging. Tension link load cells give a rugged design for resistance to side loading.
Torsion Ring – Torsion ring are a fairly new concept in design and offer a great low profile solution for a wide range of weighing applications. Unlike standard compression load cells, which can 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 particular ring, optimum load introduction is assured and off-axis loads up to three or four degrees can be tolerated without loss in performance. Proprietary mounting modules, which offer 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 would be 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 many difficulties with any weighbridge or floor scale is the risk of damaged cables. Utilizing the most advanced technology, wireless, compression load cell are now being provided and can one day become the industry standard. All of the above load cells are now obtainable in wireless format, even if this technology comes at greatly increased price.
S Type – S type have their name off their shape, being the letter ‘S’. S type load cells provides an electronic digital output when found in either tension or compression and offer superior side load rejection. This type of cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends can be attached. This sort are used in crane scales, hanging scales, hoist scales and most tension applications.
