They are are widely used in small hopper and tank weighing systems, hybrid systems with lever work, belt weighers and other load carriers with multiple load cells. Canister Style Load Cells. For a few possible load cell mechanical setups, check out the hookup guide with the load cell setup. With the multi-point type, three or four load cells are generally used to make a scale. We would like to let you know that some features on the site may not be available or may not work as nicely as they would on a newer browser version. For example, the SLS410 Tension Load Cell is the perfect economic solution toward accurate, repeatable weighing. Their main purpose is to weigh or check the amount of load transferred. When it comes to static strain measurement, the Wheatstone Bridge Circuit Theory is very popular due to its sensitivity. S type load cell / precision load cell products are designed for use with suspended tanks, dosing hoppers and other devices that are suspended from a support structure. The bi-directional units have a range between 25 and 10,000 pounds in a 2-inch diameter. 1. The load cell is constructed of aluminum in the lower capacities 50 to 1,000 pounds and capacities from 2,000 to 5,000 pounds are stainless steel. The measurement range is generally between 100kg and 20 T. If optimal hygiene and safety are both vital and it is required for precision mechanical balances, then it is recommended to use a pneumatic load cell. Generally load cells are devices that sense an applied physical force and then give an observable output quantity that is proportional to the applied force. These load cells are typically used for measuring suspended loads. As the force applied to the load cell increases, the electrical signal changes proportionally. This means that no external moments occur which makes them relatively simple to implement. Except for certain laboratories where precision mechanical balances are still used, strain gauge load cells dominate the weighing industry. They usually include a cable connection and a twist-lock connector. All services are provided in house from our engineering department, machine shop, and our full calibration lab. Tension load cell/beam type load cell offerings are typically used in a wide range of industries where precise measurements are required, and are paramount to the success and reputation of the company. At METTLER TOLEDO, we take product testing seriously, performing a variety of vigorous tests before any product hits the market. They are able to fully accommodate test benches, prototype structures, as well as industrial weighing applications.

Load Cell Selection Load cell selection in the context of trouble free operation concerns itself primarily with the right capacity, accuracy class and environmental protection, rather then with a particular measuring principle like bending, shear, compression or ring National Scale Technology provides custom load cell design and repair service. Tension load cell measures pressure and is similar to a strain gauge load cell. Tension load cells then measure the amount of pressure that is applied to the transducer casing’s exterior. Hollow Disc or Pancake Type Load Cell (from wikimedia.org) Z or S-type. These load cells provide off-center load compensation, which is ideal when manufacturing accurate scales. However, there are some heavy-duty shear beam cells that are made with carbon steel alloy that is nickel plated and corrosion resistant. Load Cell Types: Determining Which Load Cell You Need. There are many different kinds of load cells. Depending on the environment, such as operational or laboratory, there are different types of load cells. A load cell (or loadcell) is a transducer which converts force into a measurable electrical output. The Working Principle of a Compression Load Cell A load cell is a transducer that measures force, and outputs this force as an electrical signal. The load cell sensors are always bonded along with elastic material, known as strain gauges. The guideline addresses end-users who plan on purchasing process tanks and vessels, as well as machine builders, helping them to assess their current process equipment and to evaluate alternative solutions.
