Load Cell

• ELC-30S is a 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 eight 350 Ohm resistance strain gages, wired to form a 700 Ohm bridge. To minimize the effect of uneven and eccentric loading, the eight gages are mounted around the circumference at 45° to each other. The load cell is hermetically sealed by electron beam welding making it immune to ingress of water and to most corrosive environments. SPECIFICATIONS Range( kN) / ID mm) 200/ 40, 500/ 52, 1000/ 78, 1000/ 105, 1500/ 85, 1500/ 130, 2000/ 105, 2000/ 155 specify Over range capacity 150 % Calibration accuracy ± 0.25 % fs Non-linearity ± 1 % fs Output 2 mV/ V ± 10% Excitation 10 V DC ( max. 20 V DC) Temperature limit -20 to 80° C Cable connection Six pin glass to metal seal • ELC-150S-H is a resistive strain gage type load cell designed to measure large compressive load or axial forces. The load cell has extensive use in pile testing. Like ELC-210S, this load cell also has great resistance to extraneous forces and is protected against dust, moisture and adverse environmental conditions. SPECIFICATIONS Range ( kN) 5000, 6000, 7500, 10000 & 12500 Over range capacity 120 % fs with a maximum upto 14000 kN Rated output 1.5 mV/ V ± 10 % Cable Four-core shielded 5 m long; specify Other specifications same as ELC-30S
