One of the most common forms of industrial weighing scale solutions in use today are load cells. Regardless of the industry, from coast to coast and around the world, load cells have become the preeminent solution for high quality dependable weighing technology.
WHAT ARE LOAD CELLS
Load cells are electro-mechanical transducers which convert force (weight) into measurable electric ouput. Strain gauge based load cells are the most common load cell form and are differentiated by the type of output generated such as pneumatic, hydraulic or electric. They are further differentiated by the way they detect weight such as bending, shear, compression, tension, etc. Strain gauge load cells have resistors (strain gauges) built into the steel of the cell and measure shear force. A repeatable deflection of the current flowing through the load cell allow load cells to be calibrated to known weights based on the measurable electrical output they produce. Changes in electrical output are measured to determine the weight being applied.
PICKING THE RIGHT LOAD CELL
Load cells are usually selected based on the weighing application, the way the load will be supported, capacity requirements, and space limitations. |
