Model 123 Load Cell DESCRIPTION The Model 123 load cell combines both a compact form and high precision to offer a superior tension force transducer. The one-piece S-shaped design achieves a maximum non-linearity of 0.03 % full scale for load ranges from 1000 kg to 20000 kg. FEATURES • 1000 kg to 20000 kg range • ±0.03 % accuracy • Built-in overload resistance • One-piece, nickel-plated alloy steel construction • Integral cable • Cost efficient Model 123 PERFORMANCE SPECIFICATIONS RANGE CODES Characteristic Measure Range codes Range Load ranges 1000 kg to 20000 kg LQ 1000 kg Accuracy ±0.03 % full scale LR 1500 kg Output 2.0 mV/V LS 2000 kg Creep (max.) ±0.03 % full scale (30 minutes) LT 3000 kg LU 5000 kg LV 7500 kg LW 10000 kg LY 15000 kg LZ 20000 kg 4 ENVIRONMENTAL SPECIFICATIONS Characteristic Measure Temperature, operating -30 °C to 70 °C [-22 °F to 158 °F] Temperature, compensated -20 °C to 55 °C [-4 °F to 131 °F] Temperature effect, zero ±0.03 % full scale/10 °C Temperature effect, span ±0.03 % full scale/10 °C Protection class IP673 ELECTRICAL SPECIFICATIONS Characteristic Measure Strain gage type Foil Excitation (acceptable) 10 Vdc to 12 Vdc Excitation (max.) 15 Vdc Insulation resistance > 5000 mOhm Bridge resistance (tolerance) - Input resistance 400 ohm ±10 ohm (nominal) Bridge resistance (tolerance) - Output resistance 352 ohm ±2 ohm (nominal) Zero balance (tolerance) ±1 % full scale Electrical termination (std) 6 m [19.69 ft] of 5 mm [0.2 in] diameter cable MOUNTING DIMENSIONS Range (kg) A B C D 1000, 1500 80 mm [3.15 in] 70 mm [2.76 in] 25 mm [0.98 in] M12 x 1.75 2000, 3000, 5000 108 mm [4.25 in] 95 mm [3.75 in] 25 mm [0.98 in] M18 x 1.5 7500, 10000 178 mm [7.00 in] 130 mm [5.12 in] 51 mm [2.0 in] M30 x 2 15000, 20000 190 mm [7.48 in] 160 mm [6.3 in] 60 mm [2.36 in] M39 x 2 MECHANICAL SPECIFICATIONS Characteristic Measure Maximum allowable load 120 % full scale1 Later load limit 100 % full scale Material Nickel plated alloy steel NOTES WIRING CODES 1.

Allowable maximum loads – maximum load to be applied without damage.2 Without damage - loading to this level will not cause excessive zero shift or performance degradation. The user must consider fatigue life for long term use and structural integrity. All structurally critical applications (overhead loading, etc.) should always be designed with safety redundant load paths. IP68 rating for load ranges 7500 kg and greater. This unit is calibrated to Metric (non-Imperial) units.
