Description

The GTYQ-AT0503 is a multi-protocol explosion proof combustible gas detector engineered for high compatibility and stable operation in hazardous areas. It features a rugged explosion and dust ignition proof structure, complying with international safety regulations for gas detection equipment. A standard built-in alarm interface supports on-site extension, allowing users to add external alarm devices according to actual working conditions. Its dual-wire outlet design streamlines installation, and the digital sensor assembly enables calibration-free replacement, maintaining detection accuracy after maintenance. With IP66 protection, it resists dust and water intrusion to adapt to tough industrial environments. What distinguishes it is the dual communication support of XBUS and analog 4-20mA, making it compatible with most traditional and modern safety systems. It can also replace 3/4-wire 4-20mA detectors from other manufacturers, reducing upgrade costs for old monitoring networks. It is an ideal choice for natural gas and LNG monitoring in refineries, chemical facilities and utility sites.

Sensor Specification

Sensor Type Measuring Gas Measuring Range Operating Temperature Typical Life Response Time
Catalytic Type Combustible gases 0~100%LEL -40+70℃ 36 month <15sec / 90% scale

Sensor Features

​​Catalytic Type ​​Linear Output​​: Output signal shows a good linear relationship with gas concentration, enabling precise concentration readings.
High Stability​​: Minimal performance fluctuations during long-term use, ensuring reliable detection results.
High Sensitivity & Fast Response​​: Quickly captures gas concentration changes and triggers timely alerts.
​​Broad-Spectrum Capability​​: Detects ​​most flammable gases and flammable vapors​​ (e.g., hydrogen (H₂), methane (CH₄), propane (C₃H₈), ethanol vapors, etc.).
Poisoning Resistance & Low Consumption​​: Exhibits certain tolerance to common poisoning substances (e.g., silicon, lead compounds), with a long service life and low attrition rate.
