6 LINE: Enclosure Metallurgy, Waterproof Glands & Pit Ingress Protection
Summing Junction Box ArchitectureHeavy Stainless Steel / Die-Cast Aluminum Enclosure. Engineered for prolonged moisture immersion in scale pits across Iraq.
- Deep-drawn 304 heavy-gauge stainless steel or die-cast aluminum enclosure prevents pit rust.
- Continuous cellular neoprene perimeter gasket maintains elastic seal under years of compression.
- Internal and external captive lid screws made of A2/A4 grade marine stainless steel.
Hermetic barrier preventing water and chemical ingress into Summing for 4, 5, or 6 Load Cells summing terminals.
- Rated IP67 / IP68: Resists submersion in scale pit rainwater without moisture penetration.
- Equipped with 7 x Waterproof Metal Glands (6 Inputs + 1 Home Run Output) with rubber compression grommets to grip cables securely.
- Equipped with internal breathing membrane plug to equalize vapor pressure while rejecting liquid droplets.
Vibration-Proof Terminals & Corner Trim Convergence
Precision corner error calibration ensures identical reading whether truck wheel is at front, center, or rear.

- Operating Voltage: Up to 20V AC/DC compatible with all commercial indicators.
6 LINE: Regional Field Performance Across Iraq & High Water Tables
COSQC Legal VerificationHigh saline groundwater often submerges weighbridge pits during winter storms. IP68 sealed stainless boxes prevent corrosive water from shorting out cell signals.
Severe electrical ground potential differentials caused by dry soil conditions. Multi-stage 10kA surge arrestors protect sensitive indicators from lightning discharges.
Heavy aggregate haulers create intense platform vibration. Anti-vibration terminal clamps ensure zero signal interruption on high-throughput scales.
Iraqi COSQC Metrological Sealing Compliance
Features mechanical wire-seal hasps on the enclosure lid. COSQC inspectors can apply official legal lead seals after corner-balancing calibration.
