Load cells come in several shapes, sizes and capacities and are now the industry standard for all types of weighing. It may be a bit of a mine field trying to find the multi axis load cell for the application. I have listed many of the most common found today and their uses.
Single Point – Single point are probably the cheapest and a lot popular type on the market today. Due to their price and reliability, they may be found in most types of retail scales, counting scales, medical scales, parcel scales and postal scales. This kind of load cell could also be used in platform scales and industrial weighing systems to provide 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 generally the market standard for many high capacity, compression applications. Canister type load cells can be used as single and multi-weighing applications. This type of cell features a button on the top and bottom side and can be utilized in compression only. Canister type load cells are utilized 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 a number of advantages over other designs. This sort has the capacity to rock on its mountings to allow for any misalignment in mounting surfaces whilst still being retained, this also permits limited movement to enable for thermal expansion and contraction along with 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 generally seen in all kinds of floor, platform and shipping scales today and provides an excellent solution for many medium capacity weighing applications. Single ended shear cells 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 sort are really durable but may become costly and cumbersome to mount above 10,000kg. This type of load cell sensor is also offered in weighing module form.
Tension Link – The tension link are compatible with applications like 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 convenient connection to shackles, wire rope, D links or some other rigging. Tension link load cells offer a rugged design for resistance to side loading.
Torsion Ring – Torsion ring really are a relatively recent concept in design and supply an excellent low profile solution for a wide range of weighing applications. Unlike standard compression load cells, which can readily suffer from off-axis loading problems, torsion rings are loaded via a centrally located annular ring. Simply by using a central floating pin to send out load for this ring, optimum load introduction is assured and off-axis loads approximately three or four degrees could be tolerated without loss in performance. Proprietary mounting modules, that provide excellent versatility, are readily available for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally includes a load cell with mounting kit. Various types of now come supplied as modules but generally single or double 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 scales, truck weighing, vehicle scales and weighbridges.
Wireless – The suggestions above have one major flaw; they are linked to devices via cable. One of the primary problems with any weighbridge or floor scale is the possibility of damaged cables. Utilizing the ifegti technology, wireless, load cells are being made available and can 1 day function as the industry standard. The above load cells are available in wireless format, even if this technology comes at greatly increased price.
S Type – S type obtain their name from their shape, being the letter ‘S’. S type load cells can provide an electronic output when found in either tension or compression and provide superior side load rejection. This tension load cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends can be attached. This type are used in crane scales, hanging scales, hoist scales and a lot tension applications.
