Load cells come in various shapes, sizes and capacities and are now the industry standard for all types of weighing. It could be a little mine field trying to find the 3 axis load cell for your application. I have listed many of the most common found today and their uses.
Single Point – Single point are some of the cheapest and many popular type on the market today. Due to their price and reliability, they can be found in most varieties 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 supply 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 tend to be the business standard for most high capacity, compression applications. Canister type load cells can be used for single and multi-weighing applications. This kind 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 several advantages over other designs. This type has the capacity to rock on its mountings to support 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 can also be available being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are commonly seen in all sorts of floor, platform and shipping scales today and offers an ideal solution for many medium capacity weighing applications. Single ended rotary torque sensor have the capacity to withstand full capacity side load without any problems causing them to be particularly ideal for weighing systems with mixers, blenders and agitators. This sort are really durable but may become costly and cumbersome to mount above 10,000kg. This kind of cell is additionally 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 sort of load cell offers superior accuracy at high capacity weighing. This kind 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 potential to deal with side loading.
Torsion Ring – Torsion ring really are a relatively new concept in design and supply an outstanding low profile solution for an array of weighing applications. Unlike standard compression load cells, which could readily have problems with off-axis loading problems, torsion rings are loaded by way of a centrally located annular ring. By using a central floating pin to send out load to this particular ring, optimum load introduction is assured and off-axis loads as much as three or four degrees can 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 includes 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 are definitely the dzrgzs 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 are attached to devices via cable. One of many issues with any weighbridge or floor scale is the possibility of damaged cables. Utilizing the most advanced technology, wireless, load cell are now being made available and can 1 day function as the industry standard. The suggestions above load cells are available in wireless format, even if this technology comes at greatly increased price.
S Type – S type have their name using their shape, being the letter ‘S’. S type load cells can offer 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 kind are utilized in crane scales, hanging scales, hoist scales and a lot tension applications.
