As an upgraded version of the AT0503 series, the GTYQ-AT0503/d integrates real-time display functionality while retaining all core explosion-proof and detection performance. It adopts a full explosion and dust ignition proof structure, ensuring safe operation in locations with potential combustible gas leakage risks. The standard light and sound alarm interface supports on-site expansion, and the dual-wire wiring method simplifies installation for both new projects and retrofits.
The digital sensor assembly supports hot-swappable replacement without on-site calibration, ensuring continuous system operation. It supports both XBUS and 4-20mA analog communication, and is compatible with third-party 3/4-wire 4-20mA detectors for flexible system integration. The biggest highlight is its built-in LCD display, which presents real-time gas concentration values intuitively, helping operators monitor site status at a glance. With IP66 protection, it operates reliably in harsh environments. This model is suitable for industrial sites that require both remote transmission and on-site direct reading of gas data.
