Column Type/Self-Restoring Rockerpin Load Cell

The CMDC Column Load Cell by Santwell is a high-precision Load Cell   engineered for truck scales, railway scales, axle wheel scales, and floor scales. As a robust Load Cell, it delivers reliable performance across heavy-duty weighing scenarios.

Accuracy & Capacity: This Load Cell meets Class C2/C3 accuracy standards; its maximum capacities (Emax) cover 5t, 10t, 20t, 30t. TheLoad Cell’s minimum verification interval (Vmin) is 0.0200% (Emax, C2) or 0.0100% (Emax, C3), ensuring precise load measurement.

Electrical Performance: The Load Cell’s nominal sensitivity is 2.0±0.002 mV/V, with zero balance at 0±0.02 mV/V (minimizing baseline errors). Electrical specs include input resistance (400±10Ω), output resistance (352±3Ω), and excitation voltage range (5–15V DC). Insulation resistance exceeds 5000MΩ (at 50V DC), preventing electrical leakage in the Load Cell.

Stability: Temperature effects on this Load Cell’s zero balance (TKo) and sensitivity (TKc) are ±0.02% (C2) or ±0.0170% (C3) of rated output (Cn) per 10K, reducing thermal interference. Hysteresis, non-linearity, and 30-minute creep errors (±0.0270%/±0.0250%/±0.03% for C2; ±0.0180%/±0.0167%/±0.0167% for C3 of Cn) ensure the Load Cell’s consistency under dynamic loads.

Durability: This Load Cell boasts an IP68 protection rating, operating temperature range of -30℃ to +70℃, safe load limit (150% Emax), and breaking load (250% Emax). Its housing—crafted from stainless steel or alloy steel—enhances corrosion resistance and mechanical strength.

Five-Core Shielded Cable: The Load Cell’s cable boosts signal stability, anti-interference, and tensile resistance for reliable data transmission.

Polished Metal Construction: Three polishing processes enhance theLoad Cell’s structural stability and service life.

Waterproof Joints: Secure connections on the Load Cell resist electromagnetic interference and extend operational longevity.

Modular Structure: TheLoad Cell’s simple design simplifies installation while maintaining robust load-bearing capabilities.

      Optimized for heavy-duty applications, the CMDC Load Cell combines precision, resilience, and ease of use—making it a top choice for industrial weighing systems.
