Product Description

Description
πŸ’‘ The GTYQ-AT0503/d is an upgraded version of the AT0503 series β€” featuring a built-in LCD display for real-time gas concentration monitoring while retaining all core explosion-proof and detection performance.

It adopts a full explosion and dust ignition proof structure, ensuring safe operation in locations with potential combustible gas leakage risks. The standard light and sound alarm interface supports on-site expansion, and the dual-wire wiring method simplifies installation for both new projects and retrofits. The digital sensor assembly supports hot-swappable replacement without on-site calibration, ensuring continuous system operation.

It supports both XBUS and 4-20mA analog communication, and is compatible with third-party 3/4-wire 4-20mA detectors for flexible system integration. The biggest highlight is its built-in LCD display, which presents real-time gas concentration values intuitively, helping operators monitor site status at a glance. With IP66 protection, it operates reliably in harsh environments. This model is suitable for industrial sites that require both remote transmission and on-site direct reading of gas data.

Frequently Asked Questions
❓ What is the key difference between the GTYQ-AT0503/d and the standard AT0503 series?
The GTYQ-AT0503/d is an upgraded version of the AT0503 series. Its most notable enhancement is the built-in LCD display, which provides real-time on-site gas concentration readings. All core explosion-proof and detection performance from the original series is fully retained.
❓ Does the GTYQ-AT0503/d support hot-swappable sensor replacement?
Yes. The digital sensor assembly supports hot-swappable replacement without requiring on-site calibration, which ensures continuous system operation and minimizes downtime during maintenance.
❓ What communication protocols does the GTYQ-AT0503/d support?
The detector supports both XBUS (2/4 wire) and 4-20mA analog communication protocols. It is also compatible with third-party 3/4-wire 4-20mA detectors, allowing flexible integration into existing or new systems.
❓ What types of gases can the GTYQ-AT0503/d detect?
The detector uses a catalytic sensor capable of detecting most combustible gases and flammable vapors, including methane (CHβ‚„), propane (C₃Hβ‚ˆ), isobutane, hydrogen (Hβ‚‚), ethanol vapors, and more, across a measuring range of 0–100% LEL.
❓ What is the operating environment rating of the GTYQ-AT0503/d?
The GTYQ-AT0503/d features IP66 protection and is rated for operating temperatures from -40Β°C to +70Β°C, with humidity tolerance of 5–95% RH (non-condensing). It is built for reliable performance in harsh industrial environments.
❓ What is the expected sensor lifespan and response time of the GTYQ-AT0503/d?
The catalytic sensor has a typical service life of 36 months. Its response time is less than 15 seconds to reach 90% of full scale, enabling fast and timely gas concentration alerts on site.
