FUNCTIONS OF PLATFORM LOAD CELLS - Double bending beam
Platform load cells are, as the name suggests, particularly suitable for use in platform scales. The properties of a load cell are determined by the so-called spring body. This spring body is made of metal and is deformed under the influence of compressive force. The process of deformation and the return of the spring body to its original shape after the load has been removed is registered via a strain gauge and converted into an electrical signal. Platform load cells, like most other load cells, are calibrated in grams, kilograms or tons.
AREAS OF APPLICATION
Platform load cells are found in weighing devices for small to medium loads in the range of up to 1 ton. Platform load cells are used in platform scales, belt cars, filling scales or dosing scales. In addition, they can also be used to measure overload in elevators or to measure contact pressure.
TECHNICAL DETAILS
Platform load cells, like most load cells, meet the industry's high requirements for robustness. That's why load cells are usually offered with protection classes from IP 65. From a design perspective, platform load cells are actually double bending beams. Platform load cells have the advantage over other load cells in that they are optimized and calibrated for corner loads. This means that the platform load cell works very accurately even if the load on a platform is only on one corner. The data sheet contains all the information you need to construct a weighing device with platform load cells. These include the nominal load, the minimum division value for calculating the maximum tare weight and the limit load. With a platform load cell you can very quickly construct a platform scale. All you really need is the load cell platform and two metal plates to which the load cell is attached. In most cases, weighing devices are subject to mandatory calibration. This is why platform load cells can usually be calibrated.
