Tension Load Cell – Common Questions..

Load cells come in many different shapes, sizes and capacities and are now the industry standard for all sorts of weighing. It can be a bit of a mine field looking for the 3 axis load cell for your application. I have listed probably the most common found today along with their uses.

Single Point – Single point are some of the cheapest and a lot popular type on the market today. Due to their price and reliability, they may be found in most kinds 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 supply accurate readings no matter the positioning of the load on the platform, reducing manufacturing costs.

Canister Type – Canister type have been in existence for a long period and tend to be the industry standard for most high capacity, compression applications. Canister type load cells can be used for single and multi-weighing applications. This type of cell includes a button on the top and bottom side and can be utilized 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 several advantages over other designs. This kind 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 in addition to lift off protection. This kind of cell is also available as being a weighing module kit.

Single Ended Shear Beam – Single ended shear beam are commonly seen in all kinds of floor, platform and shipping scales today and supplies a perfect solution for most medium capacity weighing applications. Single ended shear cells have the ability to withstand full capacity side load with no problems causing them to be particularly suitable 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 weight sensor can also be offered in weighing module form.

Tension Link – The tension link are compatible with 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 permit for easy link to shackles, wire rope, D links or any other rigging. Tension link load cells provide a rugged design for resistance to side loading.

Torsion Ring – Torsion ring certainly are a relatively recent concept in design and supply an excellent low profile solution for an array of weighing applications. Unlike standard compression load cells, which may readily have problems with off-axis loading problems, torsion rings are loaded through 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 approximately three or four degrees can be tolerated without loss in performance. Proprietary mounting modules, which offer excellent versatility, are now readily 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 are the industry standard. Load cell weighing modules are used in tank scales, silo weighing, vessel weighing applications, axle weighing scales, truck weighing, vehicle scales and weighbridges.

Wireless – All of the above have one major flaw; these are linked to devices via cable. One of many problems with any weighbridge or floor scale is the chance of damaged cables. Using the ifegti technology, wireless, load cells are being made available and may some day function as the industry standard. All of the above load cells are available in wireless format, although this technology comes at greatly increased price.

S Type – S type obtain their name using their shape, being the letter ‘S’. S type load cells provides a digital output when found in either tension or compression and supply 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 kind are utilized in crane scales, hanging scales, hoist scales and many tension applications.
