Load cells come in many different shapes, sizes and capacities and are now the industry standard for all types of weighing. It could be a bit of a mine field searching for the multi axis force sensor for your application. These are many of the most common found today and their uses.
Single Point – Single point are the cheapest and many popular type on the market today. Because of the price and reliability, they can be found in most kinds 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 irrespective of the positioning of the load on the platform, reducing manufacturing costs.
Canister Type – Canister type have been in existence for a long period and are generally the market standard for most high capacity, compression applications. Canister type load cells can be used as single and multi-weighing applications. This kind of cell features a button on the top and bottom side and can be utilized 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 sort has the ability to rock on its mountings to accommodate any misalignment in mounting surfaces whilst still being retained, this permits limited movement to allow for thermal expansion and contraction along with lift off protection. This kind of cell is additionally available as being a weighing module kit.
Single Ended Shear Beam – Single ended shear beam are generally seen in all types of floor, platform and shipping scales today and offers an excellent solution for many medium capacity weighing applications. Single ended torque transducer 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 kind are incredibly durable but may become costly and cumbersome to mount above 10,000kg. This kind of cell is also available in weighing module form.
Tension Link – The tension link are suitable for applications including winching, hanging scales, crane weighing scales and lifting systems. This kind of load cell offers superior accuracy at high capacity weighing. This type of cell has openings at either end to enable for convenient link to shackles, wire rope, D links or some other rigging. Tension link load cells offer a rugged design for potential to deal with side loading.
Torsion Ring – Torsion ring are a fairly new concept in design and offer an excellent low profile solution for an array of weighing applications. Unlike standard compression load cells, which can readily have problems with 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 to this particular 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 provide excellent versatility, are actually available for both process weighing applications and platform scales.
Weighing Modules – Weighing module generally is made up of load cell with mounting kit. Many types of now come supplied as modules but generally single or double ended shear beam and canister type would be the dzrgzs 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 above have one major flaw; they are connected to devices via cable. One of many problems with any weighbridge or floor scale is the risk of damaged cables. Utilizing the latest technology, wireless, compression load cell are being presented and could some day function as the industry standard. The above load cells are now available in wireless format, even though 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 offer an electronic digital output when used in either tension or compression and supply superior side load rejection. This kind of cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends may be attached. This type are employed in crane scales, hanging scales, hoist scales and many tension applications.
