SHEAR BEAM LOAD CELL TYPE H8C

Product catalog summary
Overview: The document provides technical specifications for the H8C shear beam load cell manufactured by CELMI s.r.l., suitable for small capacity weighing systems such as hospital beds, floor scales, and hopper scales.
Applications: The H8C load cell is nickel-plated and adhesive-sealed, making it suitable for various weighing devices.
Main Features: The load cell is made of alloy steel and has an IP67 protection rating. It is certified by OIML with certificate number R60/2000-CN-00.03.
Nominal Load: The load cell supports nominal loads ranging from 0.5 to 10 tonnes.
Specifications According to VDI/VDE 2637:
  • Metrological Characteristics: Nominal load (Ln) ranges from 0.5 to 10 tonnes. Initial load (Lp) is 20% of Ln, and maximum load (Ll) is 150% of Ln. Non-linearity and hysteresis error are both 0.02% of Ln, while repeatability error is 0.01% of Ln. Creep over 30 minutes is ±0.03% of Ln.
  • Temperature Characteristics: Nominal temperature range is -10°C to +40°C. Zero temperature drift over 10°C is ±0.0017% of Cn, and output temperature drift is ±0.0015% of Cn. Thermal gradient is less than 5°K/h.
  • Electrical Data: Nominal output is 2 mV/V with a tolerance of ±5% of Cn. Nominal supply voltage ranges from 0.5 to 12V, with a maximum supply voltage of 18V. Input and output resistance are both 350 ±3.5%. Insulation resistance at 20V is greater than 5000 ohms. Zero output tolerance is ±1% of Cn.
  • Mechanical Data: Breaking load is 300% of Ln, and maximum side load is 100% of Ln. Deflection is less than 1 mm.
  • Environmental Conditions: Working temperature range is -35°C to +65°C, and storage temperature range is -35°C to +70°C. The housing protection is rated at IP67.
Dimensions: The document provides detailed dimensions for different capacities, including length, width, and bolt specifications.
Note: Specifications are subject to change without notice.
