ac-2a-25t Self-Restoring Rocker Pin Load Cell 25 Ton

Tool Grade Hardened Alloy Steel. Specifically engineered for Rocker Pin Compression service in Standard steel platform weighbridges, industrial weighbridges up to 80-100 tons.

• High-tensile alloy or 17-4 PH stainless steel hardened to eliminate zero shift under repetitive 45-ton tandem truck axle impacts.
• Rated for capacity of 25 Ton (25,000 kg) with safe overload margin of 150% FS and ultimate breakload of 300% FS.
• High elastic recovery prevents zero balance shift under dynamic braking and acceleration forces.

Full true hermetic enclosure with laser-welded stainless steel bellows or diaphragms (IP68 Hermetically Welded).

• Tested for continuous submersion at 1.5m water depth for 100+ hours without moisture ingress.
• Compensated temperature range (-30°C to +70°C) prevents thermal span drift in Iraqi desert climates.
• Equipped with 13m Heavy-Duty Polyurethane Sheath with internal water-blocking filler to prevent capillary fluid migration.

• Bridge Impedance: Input 750 ± 10 Ω | Output 702 ± 3 Ω ensures balanced summation in multi-cell weighbridges.
• Sensitivity Calibration: 2.0 ± 0.002 mV/V with combined error ≤ ±0.023% FS guarantees trade precision.
• Digital / Analog Summing: Direct connection to stainless junction boxes with multi-turn corner trimmers.
• Overload Barrier: Safe overload 150% FS and ultimate overload 300% FS.

High groundwater with extreme sulfate concentrations (>3,500 mg/L) causes rapid pin corrosion in generic cells. ac-2a-25t features sealed construction tested for high saline and petrochemical marine environments.

Summer ambient temperatures reach +55°C, with direct metal surface exposure exceeding +75°C. Internal temperature compensation (-30°C to +70°C) preserves legal calibration.

Cement plant complexes and aggregate quarries generate intense dust and 45-ton axle shocks. Heavy metallurgy withstands abrasive silica dust without mechanical binding.
