Compression Load Cell – Does It Be Any Better Than This..

Load cells come in several shapes, sizes and capacities and are now the industry standard for all types of weighing. It may be a slight mine field trying to find the multi axis force sensor for the application. I have listed some of 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. Because of the 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 may also be used in platform scales and industrial weighing systems to provide accurate readings irrespective of the position of the load on the platform, reducing manufacturing costs.

Canister Type – Canister type have been around for some time and are generally the business standard for many high capacity, compression applications. Canister type load cells can be used for single and multi-weighing applications. This kind of cell includes a button on the top and bottom side and can be utilized 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 several advantages over other designs. This type has the ability 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 along with lift off protection. This sort of cell is also available as being a weighing module kit.

Single Ended Shear Beam – Single ended shear beam are generally present 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 torque sensor are able to withstand full capacity side load without the problems causing them to be particularly ideal for weighing systems with mixers, blenders and agitators. This type are really durable but could become costly and cumbersome to mount above 10,000kg. This sort of cell can also be 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 kind of cell has openings at either end to permit for easy 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 supply a great low profile solution for a variety of weighing applications. Unlike standard compression load cells, which may readily have problems with off-axis loading problems, torsion rings are loaded via a centrally located annular ring. By using a central floating pin to transmit load to this ring, optimum load introduction is assured and off-axis loads up to three or four degrees may be tolerated without loss in performance. Proprietary mounting modules, that provide excellent versatility, are now designed for both process weighing applications and platform scales.

Weighing Modules – Weighing module generally consists of a 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 dzrgzs standard. Load cell weighing modules are utilized 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 may be connected to devices via cable. One of the main difficulties with any weighbridge or floor scale is the possibility of damaged cables. Making use of the most advanced technology, wireless, compression load cell are actually being made available and can one day become the industry standard. All of the above load cells are now obtainable in wireless format, although this technology comes at greatly increased price.

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