Practical Application Cases
1. Oil & Gas Onshore/Offshore Facilities: Deployed in drilling rigs, production platforms, and refineries for real-time monitoring of pressure, temperature, flow rates, and valve control in explosive gas atmospheres.
2. Chemical & Pharmaceutical Plants: Used for process automation, batch control, and safety monitoring in chemical reactors, mixing systems, and cleanroom manufacturing zones with dust and solvent hazards.
3. Petrochemical Tank Farms: Implemented as remote operator terminals for inventory management, pipeline flow control, and leak detection systems across large-scale storage facilities.
4. Mining & Mineral Processing: Integrated into conveyor control, crushing, and material-handling systems in underground and surface mines where flammable dust and gases are present.
5. Power Generation & Wastewater: Applied in biogas plants, coal-fired power stations, and hazardous wastewater treatment facilities for safe operation of pumps, blowers, and emission control equipment.
6. Marine & Shipbuilding: Installed on chemical tankers, LNG carriers, and offshore vessels for engine room monitoring, cargo handling, and safety system control in marine hazardous zones.
