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 searching for the multi axis force sensor for the application. I have listed many 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. Because of the price and reliability, they may be found in most varieties of retail scales, counting scales, medical scales, parcel scales and postal scales. This kind of load cell can 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 period and tend to be the market standard for the majority of high capacity, compression applications. Canister type load cells are used for single and multi-weighing applications. This type of cell includes a button on the top and bottom side and may be used 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 kind has the capacity to rock on its mountings to support any misalignment in mounting surfaces whilst still being retained, this permits limited movement to enable for thermal expansion and contraction along with 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 generally found 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 shear cells are able to withstand full capacity side load without any problems which makes them particularly suitable for weighing systems with mixers, blenders and agitators. This sort are incredibly durable but may become costly and cumbersome to mount above 10,000kg. This sort of load sensor is also available in weighing module form.
Tension Link – The tension link are compatible with applications such as 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 connection to shackles, wire rope, D links or any other rigging. Tension link load cells provide a rugged design for effectiveness against side loading.
Torsion Ring – Torsion ring really are a relatively new concept in design and offer an excellent low profile solution for a wide range of weighing applications. Unlike standard compression load cells, which could readily suffer from off-axis loading problems, torsion rings are loaded via a centrally located annular ring. Using a central floating pin to deliver load to this particular ring, optimum load introduction is assured and off-axis loads approximately 3 or 4 degrees could be tolerated without loss in performance. Proprietary mounting modules, which offer excellent versatility, are now designed 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 are definitely the industry standard. Load cell weighing modules are employed 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 many problems with any weighbridge or floor scale is the risk of damaged cables. Making use of the ifegti technology, wireless, load cells are being made available and can one day become the industry standard. The suggestions above load cells are actually obtainable in wireless format, although 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 provides a digital output when found in either tension or compression and offer superior side load rejection. This tension load cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends may be attached. This sort are employed in crane scales, hanging scales, hoist scales and most tension applications.
