Load cells come in many different 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 many 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 sort 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 existed for some time and are generally the industry standard for many high capacity, compression applications. Canister type load cells are used for single and multi-weighing applications. This kind of cell features 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 a number of advantages over other designs. This kind 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 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 present in all sorts of floor, platform and shipping scales today and provides an ideal solution for the majority of medium capacity weighing applications. Single ended shear cells have the ability to withstand full capacity side load without any problems making them particularly appropriate for weighing systems with mixers, blenders and agitators. This type are incredibly durable but could become costly and cumbersome to mount above 10,000kg. This type of load sensor can also be obtainable in weighing module form.
Tension Link – The tension link are suitable for applications including winching, hanging scales, crane weighing scales and lifting systems. This sort of load cell offers superior accuracy at high capacity weighing. This sort of cell has openings at either end to allow for convenient link with shackles, wire rope, D links or any other rigging. Tension link load cells offer a rugged design for effectiveness against side loading.
Torsion Ring – Torsion ring really are a relatively recent concept in design and provide an excellent low profile solution for a variety of weighing applications. Unlike standard compression load cells, which could readily are afflicted by off-axis loading problems, torsion rings are loaded by way of a centrally located annular ring. Simply 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 may be tolerated without loss in performance. Proprietary mounting modules, that offer excellent versatility, are now available for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally consists of 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 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 may be connected to devices via cable. One of the primary issues with any weighbridge or floor scale is the chance of damaged cables. Utilizing the ifegti technology, wireless, load cells are being presented and could 1 day be the industry standard. The above load cells are actually offered in wireless format, even if this technology comes at greatly increased price.
S Type – S type get their name using their shape, being the letter ‘S’. S type load cells can provide an electronic digital output when found in either tension or compression and offer superior side load rejection. This force sensor has two female threaded fixing points, top and bottom were eye bolts or thread rod ends could be attached. This sort are used in crane scales, hanging scales, hoist scales and a lot tension applications.
