Ex-Proof Weighing Scales
Certified Weighing Solutions for Hazardous Industrial Environments
Ex-proof weighing scales are designed for use in locations where flammable gases, vapours, or combustible dust may be present during normal operation. These weighing systems combine certified explosion protection with reliable industrial weighing performance, making them suitable for oil and gas, petrochemical, pharmaceutical, chemical, paint, and other hazardous industrial environments.
Himatrix Arabia supplies ATEX and IECEx certified weighing solutions that can be configured to meet different hazardous area classifications, helping businesses select equipment that supports both operational requirements and site safety regulations.
Hazardous Area Zone Classification
Selecting the correct hazardous area classification is the first step when choosing an Ex-proof weighing solution. Each zone represents a different level of explosion risk and requires equipment certified specifically for that environment.
| Zone | Hazard Type | Typical Environment |
|---|---|---|
| Zone 0 | Gas / Vapour | Explosive atmosphere continuously present or for long periods |
| Zone 1 | Gas / Vapour | Explosive atmosphere likely during normal operation |
| Zone 2 | Gas / Vapour | Explosive atmosphere unlikely or present only briefly |
| Zone 21 | Combustible Dust | Explosive dust cloud likely during normal operation |
| Zone 22 | Combustible Dust | Explosive dust cloud unlikely or present only briefly |
The appropriate zone classification should always be confirmed before selecting hazardous-area weighing equipment.
Technical Configuration Overview
| Parameter | Typical Configuration |
|---|---|
| Capacity Range | Model Dependent |
| Product Types | Bench Scales, Floor Scales, Precision Balances |
| Construction | Stainless Steel Construction |
| Indicator Protection | IP Rated Model Dependent |
