Load Cell Model ELC-30S-H (MTI.EWS.ER.M-ELC-30S-H). The center hole load cell comprises of a cylinder of high strength martensitic stainless steel. It generally uses eight 350 Ohm resistance strain gages, wired to form a 700 Ohm bridge for capacity 3500 kN and 5000 kN. For capacities above 5000 kN, sixteen 350 Ohm resistance strain gages are used to form a 1400 Ohm bridge. To minimize the effect of uneven and eccentric loading, the strain gages are equally spaced along the circumference. Load applied to the cell can be measured by using any standard digital read-out unit suitable for resistive strain gage type sensors. The data can also be automatically collected at desired frequency, stored and transmitted to remote server by a suitable datalogger using multiplexer/ busmux or SDI 12 digital interface. The sectional area of the element is varied in the different capacity load cells to give approximately the same millivolt output for a variation of zero to full load.
