Checkweighers in Chemical and Bulk Processing

1. Introduction to Chemical Industry Checkweighing

Checkweighers in chemical and bulk processing ensure accurate formulation, regulatory compliance,

and safe handling of hazardous or high-value materials. These systems must meet strict standards for:
✔ Explosion-proof operation (ATEX/IECEx)
✔ Corrosion resistance (acid/alkali compatibility)
✔ Dust containment (for powders and granules)
✔ Batch traceability (REACH, GHS compliance)

2. Specialized Features

Vapor-proof load cells for solvent environments
Pneumatic rejection (no spark risk)
Washdown-ready models for pharma-grade chemicals
Intrinsically safe HMI (Class I Div 1)

3. Advanced Technologies

3.1 Hazardous Area Innovations

Fiber-optic load cells (spark-free)
AI-based density compensation for aerated powders
Blockchain batch records for anti-tampering

3.2 Maintenance & Calibration

Remote diagnostics via AR glasses
Self-calibrating mass comparators
Predictive analytics for load cell drift

Conclusion:
Chemical industry checkweighers merge intrinsic safety engineering with laboratory-grade

precision, enabling compliant handling of hazardous materials while optimizing batch yields.
