Load cells come in many different shapes, sizes and capacities and are now the industry standard for all sorts of weighing. It could be a slight mine field trying to find the multi axis load cell for your application. These are some of the most common found today along with their uses.
Single Point – Single point are the cheapest and a lot popular type on the market today. Due to their price and reliability, they are available 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 provide accurate readings regardless of the position of the load on the platform, reducing manufacturing costs.
Canister Type – Canister type have been around for some time and are usually the business standard for the majority of 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 used 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 numerous advantages over other designs. This sort has the capacity to rock on its mountings to accommodate any misalignment in mounting surfaces whilst still being retained, this also permits limited movement to allow for thermal expansion and contraction in addition to 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 commonly present in all sorts of floor, platform and shipping scales today and offers an ideal solution for most medium capacity weighing applications. Single ended rotary torque sensor have the ability 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 may become costly and cumbersome to mount above 10,000kg. This sort of cell is additionally obtainable 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 sort of cell has openings at either end to permit for convenient link to shackles, wire rope, D links or 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 an array 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. Using a central floating pin to deliver 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, which 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 types of now come supplied as modules but generally single or double ended shear beam and canister type are definitely 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; these are linked to devices via cable. One of the primary issues with any weighbridge or floor scale is the possibility of damaged cables. Using the latest technology, wireless, load cell are actually being presented and may one day be the industry standard. The above load cells are obtainable in wireless format, although 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 utilized in either tension or compression and provide superior side load rejection. This type of cell 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 many tension applications.
