1.Product Overview
The GTYQ-JSY-201/A point-type combustible gas detector for industrial and commercial use (hereinafter referred to as the detector) is an explosion-proof instrument that integrates concentration display, audible and visual alarm, and ambient temperature monitoring.
The detector detects gas concentration through natural diffusion. It uses a catalytic combustion sensor, which has excellent sensitivity and outstanding repeatability. A segment code LCD screen suitable for industrial applications displays the concentration value of the leaked gas and the ambient temperature in real-time. When the gas concentration or ambient temperature reaches the alarm set value, the detector emits a rapid audible and visual alarm signal and can output a control signal to drive the exhaust system. The standard 4 - 20mA signal can be directly connected to the industrial DCS system. It can also be connected to the M201 combustible gas alarm controller produced by our company via RS485 to monitor and summarize the status of each detector in real-time, facilitating unified management. When connected to the M201 host, the PowerBus two - wire system can also be used, making the wiring simpler and more efficient. The detector adopts embedded micro - control technology, featuring simple operation, comprehensive functions, and high reliability.
