High-Quality GTYQ-XP4000 Explosion Proof Combustible Gas Detector Suppliers, Manufacturer

Product Description

Description

The GTYQ-XP4000 is an advanced multi-protocol explosion proof combustible gas detector designed for intelligent industrial safety systems. It has a complete explosion and dust ignition proof structure, meeting strict safety requirements for flammable gas monitoring. It provides dual-channel relay output with independent high and low alarm functions, supporting graded linkage control for different risk levels. Supporting both XBUS 2-wire and analog 4-20mA communication, it ensures high compatibility with new and legacy safety systems. The digital sensor assembly supports calibration-free replacement, and the IP66 protection rating enables stable operation in harsh environments. It is equipped with a built-in two-stage sound-light alarm and a high-brightness digital tube display for timely and visible warnings. With an extended Modbus protocol, it can be connected to PLC and DCS systems via BUS for centralized management. The standard expansion port supports 4-20mA, HART, RS485 and relay output, making it a core device for intelligent gas monitoring in modern industrial sites.
