Load cells come in several shapes, sizes and capacities and therefore are the industry standard for all sorts of weighing. It’s really a small mine field looking for the right load cell for the application. These are merely probably the most common found today as well as their uses.
Anchorman are most likely the least expensive and many popular type currently available. Due to their cost and reliability, they are available in most kinds of retail scales, counting scales, medical scales, parcel scales and postal scales. This kind of load cell may also be used in platform scales and industrial weighing systems to supply accurate readings no matter the positioning of the strain on the woking platform, reducing manufacturing costs.
Canister type have been in existence for any lengthy time and they are the standard for many 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 top and bottom side and could be utilized in compression only. Canister type load cells are utilized in tank scales, vessel weighing applications, axle weighing machines, truck weighing, vehicle scales and weighbridges. Canister type load cells offer accurate hitting the scales harsh environments.
Double Ended Shear Beam
For medium to high capacity applications, the double ended shear beam offers a number of benefits over other kinds. This kind is able to rock on its mountings to support any imbalance in mounting surfaces although still being retained, this permits limited movement to match thermal expansion and contraction in addition to lift off protection. This kind of cell can also be like a weighing module package.
Single Ended Shear Beam
Single ended shear beam are generally present in all kinds of floor, platform and shipping scales today and offers a perfect solution for many medium capacity weighing applications. Single ended shear cells be capable of withstand full capacity side load with no problems causing them to be particularly appropriate for weighing systems with mixers, blenders and agitators. This kind are very durable but could become pricey and cumbersome to mount above 10,000kg. This kind of cell can also be obtainable in weighing module form.
The strain link are appropriate for applications for example winching, hanging scales, crane weighing machines and lifting systems. This kind of load cell offers superior precision at high capacity weighing. This kind of cell has openings at either finish to match easy link with shackles, wire rope, D links or any other rigging. Tension link load cells give a rugged the perception of potential to deal with side loading.
Torsion ring really are a relatively recent concept in design and supply a great 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 via a located annular ring. Using a central floating pin to deliver load for this ring, optimum load introduction is assured and off-axis loads as much as 3 or 4 levels could be tolerated without reduction in performance. Proprietary mounting modules, that offer excellent versatility, are actually readily available for both process weighing applications and platform scales.
Weighing module generally includes a load cell with mounting package. Various kinds of now come provided as modules but generally double or single ended shear beam and canister type would be the industry standard. Load cell weighing modules are utilized in tank scales, silo weighing, vessel weighing applications, axle weighing machines, truck weighing, vehicle scales and weighbridges.
The suggestions above get one major flaw they’re linked to devices via cable. Among the primary issues with any weighbridge or floor scale is the risk of broken cables. While using most advanced technology, wireless, load cells are increasingly being provided and may eventually function as the industry standard. The suggestions above load cells are actually obtainable in wireless format, even though this technology comes at greatly elevated cost.
S type obtain name using their shape, to be the letter ‘S’. S type load cells can offer an electronic output when utilized in either tension or compression and supply superior side load rejection. This kind of cell has two female threaded fixing points, bottom and top were eye bolts or thread fishing rod ends could be attached. This kind are utilized in crane scales, hanging scales, hoist scales and many tension applications.
