Product Name: Fixed Nitrogen Gas Detection Alarm
Product Model: JQB-G-N2
Product Description:
JQB-G-N2 Fixed Nitrogen Gas Detection Alarm is a newly developed gas detector by Kunlun Coast, featuring original imported sensors and a new 32-bit low-power processor. It has a dashboard display interface that shows both numerical values and progress bars, offering an aesthetically pleasing and elegant design. The circuit uses 4-layer wiring for stronger weak signal handling and anti-interference capabilities. With imported 16-bit AD chips and unique signal processing algorithms, the measurement data is more accurate and stable. Multiple output signals such as 4~20mA, RS485, and 200~1000Hz are available, making it easy to connect to various alarm controllers, PLCs, DCS, and other control systems. The explosion-proof structural design allows it to be used in various hazardous industrial environments. The product is widely applied in industries such as metallurgy, petroleum, petrochemicals, municipal engineering, and chemicals.
