Load cells come in various shapes, sizes and capacities and are now the industry standard for all sorts of weighing. It can be a slight mine field looking for the 3 axis load cell for your application. These are probably the most common found today along with their uses.
Single Point – Single point are probably the cheapest and a lot popular type on the market today. Because of the price and reliability, they are available in most kinds of retail scales, counting scales, medical scales, parcel scales and postal scales. This type of load cell could also be used in platform scales and industrial weighing systems to offer accurate readings regardless of the position of the load on the platform, reducing manufacturing costs.
Canister Type – Canister type have been around for a long time and are generally the business standard for many high capacity, compression applications. Canister type load cells can be used as single and multi-weighing applications. This kind of cell includes a button on the top and bottom side and can 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 numerous advantages over other designs. This kind is able to rock on its mountings to support any misalignment in mounting surfaces whilst still being retained, this permits limited movement to allow for thermal expansion and contraction as well as lift off protection. This type of cell is additionally available as being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are commonly seen in all kinds of floor, platform and shipping scales today and supplies an ideal solution for most medium capacity weighing applications. Single ended torque sensor are able to withstand full capacity side load without any problems making them particularly suitable for weighing systems with mixers, blenders and agitators. This sort are really durable but could become costly and cumbersome to mount above 10,000kg. This type of cell can also be 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 sort of load cell offers superior accuracy at high capacity weighing. This type of cell has openings at either end to allow for convenient link with shackles, wire rope, D links or some other rigging. Tension link load cells provide a rugged design for effectiveness against side loading.
Torsion Ring – Torsion ring are a relatively recent concept in design and provide an outstanding 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 via a centrally located annular ring. Using a central floating pin to send out load for this ring, optimum load introduction is assured and off-axis loads approximately 3 or 4 degrees can be tolerated without loss in performance. Proprietary mounting modules, that provide excellent versatility, are now 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 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 – All of the above have one major flaw; they are connected to devices via cable. One of the main issues with any weighbridge or floor scale is the risk of damaged cables. Using the latest technology, wireless, load cell are now being presented and may some day function as the industry standard. All of the above load cells are available 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 can offer an electronic output when utilized in either tension or compression and provide 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 sort are employed in crane scales, hanging scales, hoist scales and many tension applications.
