Explosion-Proof Scales & Hazardous Area Weighing Systems
Ensure plant safety and precise weight measurement in classified hazardous environments with certified explosion-proof scales from ZFA. Request an engineering consultation and competitive quotation for intrinsically safe bench, platform, and drum scales tailored to your operational zone.
Explosion-proof scales provide verified weight measurement in classified hazardous environments containing flammable vapors, gases, and combustible dusts. With over 17 years of experience, ZFA supplies certified intrinsically safe weighing systems for chemical plants, refineries, and high-risk processing.
- Hazardous Zone & Classification: Engineered for Zone 1/21 and Zone 2/22 across Gas Groups IIA, IIB, and IIC, operating safely within certified T-rating surface temperature limits.
- Intrinsically Safe & Flameproof Design: Employs intrinsic safety circuits and explosion-proof enclosures paired with galvanic isolators and Zener barriers to eliminate electrical spark ignition risks.
- Bench, Platform & Drum Form Factors: Available in compact bench units for dosing, low-profile floor platforms for bulk pallets, and drum scales equipped with integral access ramps.
- Stainless Steel & Antistatic Construction: Built from 304/316 stainless steel with conductive grounding, laser-welded IP66/IP68 hermetic sealing, and washdown-ready sanitary enclosures.
- Isolated Signals & Safe Connectivity: Interfaces with hazardous-area digital indicators and safe-area PLCs or PCs via optocoupler-isolated serial RS485, Modbus, or analog 4–20mA outputs.
- Ex-Certified Batteries & Power Supplies: Powered by intrinsically safe rechargeable battery packs or certified explosion-proof power units, supporting mobile and off-grid hazardous weighing.
- Regional Sourcing & Compliance Support: ZFA assists refineries, petrochemical plants, and pharmaceutical facilities across Egypt, Saudi Arabia, the UAE, and the GCC with equipment selection and calibration.
