Load Cell Model ELC-30S (MTI.EWS.ER.M-ELC-30S). The center hole load cell comprises of an element of high strength martensitic stainless steel. It uses eight 350 Ohm resistance strain gages, wired to form a 700 Ohm bridge. To minimize the effect of uneven and eccentric loading, the eight strain gages are mounted at 45° to each other in a groove at the base of a stainless steel columnar element. The strain gages are mounted in a groove at the base of a stainless steel columnar element. A stainless steel diaphragm is electron beam welded to the element to cover the groove resulting in a vacuum of around 1/1000 Torr inside the sensor. All this helps in sensor becoming immune to atmospheric corrosion and effect of ingress of water. The sectional area of the columnar element and the depth of the groove in it is varied in different capacity load cells to give approximately the same mV/V output for a variation of zero to full load. 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.
