Aluminum Explosion-Proof Sensors (Fuel System & Industrial Automation Control)
In environments with flammable and explosive gases, precise measurement and safety control are critical. The FBCGQ Series explosion-proof sensors are engineered for hazardous areas, fully compliant with GB3836 standards, with an explosion-proof rating of Exd IIB T4. They can safely operate in Zone 1 and Zone 2 areas with flammable gas mixtures of groups IIA and IIB. These sensors feature a built-in mechanical counter and an anti-reverse function, ensuring accurate and stable data.

Explosion-proof sensors for fuel systems are known by different names worldwide, depending on regional standards and hazardous area requirements. In North America and Europe, these devices are commonly referred to as explosion-proof sensors, flameproof sensor modules, fuel flow sensors for hazardous areas, or ATEX certified sensor. In France, they are typically called capteur antidéflagrant or capteur de débit pour zone explosive. In Spain and Latin America, users may search for sensor a prueba de explosión or sensor de flujo para áreas peligrosas. In Germany, common terms include explosionsgeschützter Sensor or flammgeschütztes Messgerät. Across Asian markets, these sensors are widely described as 防爆流量传感器, 防火测控传感器, 燃油计量传感器, or simply ATEX certified sensor.
