In 1833 a British Mathematician Mr. Samuel Hunter Christie wrote the “diamond method” ; this theory was used in 1843 by Mr. Charles Wheatstone to submit in paper to the British Royal Society, the electric properties of metals, like a method for comparing millivolts electric circuits in those metals; the Wheatstone bridge concept has born. Since those days this Load cells concept was apply in measurement with high accuracy the very low electric resistances in different material, used now in force measure, temperature force, pressure force and weigh, using in the load cells measurements; used as weighing sensors, digital load cells, electronic load cells or analog load cells and sensors for many laboratory balances and Industrial scales. Since 1997 Load Cells Mr., is leader in manufacture load cells with the Brand Sentronik, and distribute many other brands like Vishay, Sensotronics, Revere transducers, Tedea Huntleigh, Celtron, HBM, BLH, Artech, Anyload, Coti, Amcells, Rice Lake load cells, Cardinal, Fairbanks, Ohaus, AND, Dillon, Flintec, Salter and Sartorius.
