Resistive Strain Gage Type Anchor Bolt Load Cell

Anchor Bolt Load Cell
Model ELC-30S-H

ELC-30S-H is a high capacity resistive strain gage type center hole load cell used to determine load in rock bolts, tieback anchors, etc. It comprises of a cylinder of high strength steel with sixteen 350 Ohm resistance strain gages, wired to form a 1400 Ohm bridge. To minimize the effect of uneven and eccentric loading, the sitxeen gages are mounted around the circumference. The 3500/185 and 5000/202 load cells are hermetically sealed by electron beam welding making it immune to ingress of water and to most corrosive environments.
