High Capacity Center Hole Load Cell

View Related Products

 The ELC-30S-H is a high capacity center hole resistive strain gage type load cell. It is used to determine the load in rock bolts, tieback anchors, etc through a center hole. It is similar to the ELC-30S load cell. 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.
