Product Overview
GD200-D Detection for Industrial Safety
The GD200-D is a rugged, explosion-proof online gas detector designed for 24/7 monitoring of toxic, combustible, and asphyxiant gases-including LEL, O₂, CO₂, CO, H₂S, NH₃, VOCs, and more.
Supporting over 30 plug-and-play sensor modules, it adapts to diverse safety requirements across oil & gas, chemical plants, power stations, and urban infrastructure. With Ex d IIC T6 certification, IP66 protection, and a die-cast aluminum housing, the unit operates reliably in extreme conditions: –30°C to +65°C, up to 95% RH, and dusty or corrosive atmospheres.
Featuring infrared remote configuration, standard 4–20 mA / relay outputs, and optional RS-485 (Modbus), the SafeGuard X integrates seamlessly into fire & gas systems, PLCs, and central safety platforms-delivering fast, accurate alerts with minimal maintenance.
Key Features
✅ High-Accuracy Multi-Gas Monitoring
Measures critical gases with ≤ ±3% full-scale accuracy, T90 response ≤ 30 seconds, and low zero drift (≤ ±1% FS/year). Ideal for early leak detection and personnel protection.
✅ Field-Replaceable Sensor Modules
Hot-swappable sensors are factory pre-calibrated for rapid deployment. While replacement is quick, zero/span verification is recommended after installation to ensure compliance with safety standards (e.g., IEC 60079-29-1).
✅ Non-Contact Maintenance via IR Remote
Configure alarms, run diagnostics, or perform calibration without opening the enclosure-eliminating hot work permits and reducing exposure risk in hazardous zones.
✅ Built for Harsh Industrial Environments
Explosion protection: Ex d IIC T6 (suitable for Zone 1)
Ingress protection: IP66 (dust-tight, protected against powerful water jets)
Housing: Die-cast aluminum, corrosion-resistant finish
Power: Wide-range DC 12–30 V, compatible with most industrial supplies
✅ Flexible Installation & Detection Modes
Mounting: Wall-mounted, compact (<1.8 kg)
Sampling: Diffusion (standard) or pump-assisted suction (optional for remote or low-flow areas)
Display: Color LCD for real-time status, alarm history, and diagnostics
✅ Seamless System Integration
Standard outputs: 3-wire 4–20 mA + two SPDT relays (for local alarms or shutdowns)
Optional: RS-485 (Modbus RTU) for digital communication
Alarm: Optional integrated audible/visual beacon for on-site warning
