Description

Designed for safe flammable gas monitoring in explosive atmospheres, the GTYQ-AT0502 holds complete explosion and dust ignition proof certification to meet strict industrial safety standards. It integrates a standard light and sound alarm module with on-site expandable interfaces, ensuring timely and clear alerts once abnormal gas concentration is detected. The dual-wire wiring structure brings convenience to installation and retrofitting projects, while the digital sensor component can be replaced directly without field calibration, greatly reducing maintenance difficulty and downtime. Boasting an IP66 ingress protection level, it performs reliably in harsh outdoor and indoor environments with severe dust and water spray. This model is compatible with XBUS 2-wire and HBUS 4-wire detectors, offering flexible replacement options for old system upgrades. It is suitable for natural gas and LNG monitoring scenarios, and provides stable, low-maintenance detection solutions for petrochemical, metallurgical and urban gas pipeline projects.

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.
