BTYQ-GYQ-TCB2 Gas Station Magnetic Wireless Combustible Gas Detector

BTYQ-GYQ-TCB2 Gas Station Magnetic Wireless Combustible Gas Detector

Add combustible-gas monitoring where running new signal cables is difficult.

  • Plan a practical installation

    Magnetic mounting and battery-powered operation may simplify suitable installations.

  • See local alarms

    Audible and visual alerts indicate a configured gas alarm at the detector.

  • Specify the reporting path

    Choose the wireless network and alarm integration for your site before ordering.

Mounting, network coverage and gas options depend on the selected configuration and site survey.

Overview

The BT-GYQ-TCB2 Fixed Gas Detector Alarm, a low-power gas sensor developed by our company, is designed for environments requiring gas concentration monitoring and leak detection. Primarily used in gas stations, CNG stations, and storage facilities for flammable/explosive gases, this advanced device combines high-performance gas sensors with microcomputer technology and energy-efficient design. It offers advantages including power-saving operation, intuitive display, reliable performance, long service life, magnetic installation, cabling-free operation, easy maintenance, and user-friendly operation.

Powered by batteries, the detector transmits gas concentration data, battery status, and anomaly alerts via LoRa/NB/4G wireless networks to the control host in scheduled or event-triggered modes. Integrated with system software, it enables centralized monitoring of gas levels at multiple field sites, supporting statistical analysis, real-time queries, and automated backup operations. This detector is designed for continuous monitoring and early warning of gas concentrations. It is suitable for use in Zone 1 or 2 of explosive gas environments with Group II A, II B, II C, and T1-T6 categories, as well as in Zone 21 and 22 of combustible dust environments.
