Output signal shows a good linear relationship with gas concentration, enabling precise concentration readings.
Minimal performance fluctuations during long-term use, ensuring reliable detection results.
Quickly captures gas concentration changes and triggers timely alerts.
Detects most flammable gases and flammable vapors (e.g., hydrogen, methane, propane, ethanol vapors, etc.).
Exhibits tolerance to common poisoning substances (e.g., silicon, lead compounds) with a long service life and low attrition rate.
The GTYQ-AT0503 features dual communication support, incorporating both XBUS (2/4 wire) and analog 4-20mA. This makes it compatible with a wide range of traditional and modern industrial safety systems.
Yes. With an IP66 ingress protection rating and an aluminum alloy housing, the detector resists dust and water intrusion. It is designed to operate in challenging environments with temperatures ranging from -40°C to +70°C.
Absolutely. The device uses a digital sensor assembly that supports calibration-free replacement. This allows for quick on-site maintenance without compromising detection accuracy.
The catalytic type sensor has a broad-spectrum capability, allowing it to detect most flammable gases and vapors, such as methane (CH₄), propane (C₃H₈), hydrogen (H₂), isobutane, and ethanol vapors.
Yes, it features a standard built-in alarm interface (light and sound output / 50mA) that allows users to easily add external alarm devices on-site based on specific working conditions.
The catalytic sensor offers a typical lifespan of 36 months under standard conditions. It features high sensitivity and a fast response time of less than 15 seconds to reach 90% of the scale.
