This is a high capacity centre hole resistive strain gauge type load cell. It is used to determine the load in rock bolts, tieback anchors, etc through a centre hole. It comprises of sixteen 350 Ohm resistance strain gages, wired to form a 1400 Ohm bridge, inside a stainless steel cylinder of high steel strength, in a load cell with a capacity above 5000 kN. The 3500/185 and 5000/202 load cells are welded using the electron beam welding technique.
