Load cells come in many different shapes, sizes and capacities and are now the industry standard for all types of weighing. It can be a bit of a mine field searching for the 3 axis load cell for your application. These are some of the most common found today along with their uses.
Single Point – Single point are some of the cheapest and most popular type on the market today. Due to their price and reliability, they are available in most varieties of retail scales, counting scales, medical scales, parcel scales and postal scales. This sort of load cell can 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 existed for a long period and tend to be the industry standard for the majority of high capacity, compression applications. Canister type load cells are used for single and multi-weighing applications. This kind of cell includes a button on the top and bottom side and can be utilized 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 numerous advantages over other designs. This sort has the ability to rock on its mountings to allow for 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 sort of cell can also be available as being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are normally seen in all sorts of floor, platform and shipping scales today and offers an ideal solution for the majority of 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 type are really durable but can become costly and cumbersome to mount above 10,000kg. This type of cell is also offered in weighing module form.
Tension Link – The tension link are suitable for applications like winching, hanging scales, crane weighing scales and lifting systems. This sort of load cell offers superior accuracy at high capacity weighing. This type of cell has openings at either end to permit for quick link with shackles, wire rope, D links or any other rigging. Tension link load cells provide a rugged design for potential to deal with side loading.
Torsion Ring – Torsion ring are a fairly new concept in design and supply a great low profile solution for a variety of weighing applications. Unlike standard compression load cells, which could readily suffer from off-axis loading problems, torsion rings are loaded by way of a centrally located annular ring. By using a central floating pin to deliver load to this ring, optimum load introduction is assured and off-axis loads as much as 3 or 4 degrees can be tolerated without loss in performance. Proprietary mounting modules, which offer excellent versatility, are designed for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally consists of a load cell with mounting kit. Many 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 above have one major flaw; they are linked to devices via cable. One of many issues with any weighbridge or floor scale is the chance of damaged cables. Making use of the latest technology, wireless, miniature load cell are actually being provided and may 1 day be the industry standard. The suggestions above load cells are now obtainable in wireless format, although 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 provides an electronic output when used in either tension or compression and supply superior side load rejection. This sort of cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends can be attached. This type are utilized in crane scales, hanging scales, hoist scales and many tension applications.
