Description
The GTYQ-AT0501 is a professional explosion and dust ignition proof detector dedicated to continuous monitoring of natural gas, LNG and other flammable gases in hazardous industrial locations. It comes with a standard audible and visual alarm interface, supporting on-site expansion to match diverse site alert requirements. Equipped with a dual-wire outlet, this unit simplifies on-site wiring and installation, cutting down construction time and labor costs. Its digital sensor assembly supports plug-and-play replacement, eliminating the need for complicated on-site calibration and ensuring stable detection performance. With an IP66 protection grade, it adapts to harsh working environments with heavy dust, moisture and temperature fluctuations. The detector supports both XBUS 2-wire and 4-wire communication protocols, enabling smooth integration with mainstream safety monitoring systems. It is widely applied in oil refineries, chemical plants, gas storage stations and manufacturing workshops, delivering reliable and long-term gas monitoring to prevent leakage risks and protect on-site workers and equipment safety.
