Miniature Load Cell – Find Out More..

Load cells come in various shapes, sizes and capacities and are now the industry standard for all types of weighing. It can be a bit of a mine field trying to find the right load cell for the application. I have listed some of the most common found today as well as 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 can be found in most kinds of retail scales, counting scales, medical scales, parcel scales and postal scales. This type of load cell may also be used in platform scales and industrial weighing systems to provide accurate readings no matter the positioning of the load on the platform, reducing manufacturing costs.

Canister Type – Canister type have existed for a long time and are generally the industry standard for the majority of high capacity, compression applications. Canister type load cells can be used as Torque Measurement. This type of cell features 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 is able to rock on its mountings to allow for any misalignment in mounting surfaces whilst still being retained, this too permits limited movement to allow for thermal expansion and contraction in addition to lift off protection. This type of cell is also available being a weighing module kit.

Single Ended Shear Beam – Single ended shear beam are normally present in all kinds of floor, platform and shipping scales today and offers an excellent solution for many medium capacity weighing applications. Single ended shear cells have the capacity to withstand full capacity side load without any problems which makes them particularly ideal for weighing systems with mixers, blenders and agitators. This kind are really durable but could become costly and cumbersome to mount above 10,000kg. This sort of cell is also available in weighing module form.

Tension Link – The tension link are suitable for applications such as winching, hanging scales, crane weighing scales and lifting systems. This sort of load cell offers superior accuracy at Compression Load Cell. This type of cell has openings at either end to permit for easy connection to shackles, wire rope, D links or any other rigging. Tension link load cells provide a rugged design for effectiveness against side loading.

Torsion Ring – Torsion ring really are a relatively recent concept in design and provide an outstanding low profile solution for a variety of weighing applications. Unlike standard compression load cells, which may readily are afflicted by off-axis loading problems, torsion rings are loaded by way of 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 approximately three or four 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 includes 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 the industry 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 may be attached to devices via cable. One of many difficulties with any weighbridge or floor scale is the risk of damaged cables. Using the latest technology, wireless, load cells are being presented and could one day function as the industry standard. The suggestions above load cells are now offered in wireless format, although omqzxd 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 3 Axis Force Sensor when found in either tension or compression and offer superior side load rejection. This sort of 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 many tension applications.
