Multi Axis Force Sensor – Current Information..

Load cells come in various shapes, sizes and capacities and are now the industry standard for all types of weighing. It may 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 as well as their uses.

Single Point – Single point are the cheapest and a lot popular type on the market today. Because of their price and reliability, they can 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 provide accurate readings regardless of the position of the load on the platform, reducing manufacturing costs.

Canister Type – Canister type have been in existence for some time and are generally the market standard for the majority of 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 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 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 permit for thermal expansion and contraction in addition to lift off protection. This kind of cell is also available as a weighing module kit.

Single Ended Shear Beam – Single ended shear beam are commonly seen in all types of floor, platform and shipping scales today and offers an ideal solution for many medium capacity weighing applications. Single ended shear cells are able to withstand full capacity side load with no problems which makes them particularly suitable for weighing systems with mixers, blenders and agitators. This kind are incredibly durable but can become costly and cumbersome to mount above 10,000kg. This kind of load sensor is also offered in weighing module form.

Tension Link – The tension link are suitable for applications including winching, hanging scales, crane weighing scales and lifting systems. This type of load cell offers superior accuracy at high capacity weighing. This kind of cell has openings at either end to allow for quick link to shackles, wire rope, D links or any other rigging. Tension link load cells provide a rugged design for potential to deal with side loading.

Torsion Ring – Torsion ring are a fairly new concept in design and provide an excellent low profile solution for a wide range of weighing applications. Unlike standard compression load cells, which can readily suffer from 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 as much as three or four degrees could be tolerated without loss in performance. Proprietary mounting modules, that offer excellent versatility, are designed 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 – The above have one major flaw; these are attached to devices via cable. One of the main problems with any weighbridge or floor scale is the chance of damaged cables. Utilizing the ifegti technology, wireless, load cells are being provided and could one day be the industry standard. The above load cells are actually obtainable in wireless format, even though this technology comes at greatly increased price.

S Type – S type have their name using their shape, being the letter ‘S’. S type load cells can provide a digital output when found in either tension or compression and supply superior side load rejection. This tension load cell has two female threaded fixing points, top and bottom were eye bolts or thread rod ends can be attached. This type are used in crane scales, hanging scales, hoist scales and a lot tension applications.
