Technical Specifications Power Supply: 24V DC Operating Temperature: -40℃ ~ 70℃ Mounting: Wall or pipe bracket mounting Signal Output: Standard analog/digital signal Protection Grade: IP66
Functional Features Continuous real-time gas concentration detection. Gas signal conversion and transmission to main controller. Built-in self-diagnosis for sensor fault. Anti-interference design for industrial ambient noise. Stable performance under high humidity and dusty environment. Alarm signal output when gas concentration exceeds limit.
Application Scenarios Petrochemical plant, refinery gas safety monitoring. Chemical factory, oil & gas station fire and gas protection system. Power plant and industrial workshop toxic and combustible gas detection. Honeywell fire & gas detection system maintenance spare module. Explosion-proof industrial safety monitoring subsystem.
Performance Parameters Response speed: Fast gas detection response Zero drift: Low signal drift under temperature fluctuation Environmental tolerance: Adapt to dusty and high humidity environment Self-check function: Automatic sensor fault identification
Material Composition Housing: Explosion-proof cast aluminum alloy Sensing element: Industrial gas sensitive sensor Internal PCB: High reliability industrial circuit board
Structural Characteristics Sealed explosion-proof housing assembly. Gas diffusion inlet for ambient gas sampling. Cable gland port for field cable entry. Metal mounting bracket for wall or pipe installation. Fully sealed internal structure for dust and water protection.
Working Principle Ambient gas enters the sensor through gas diffusion inlet. The sensing element measures gas concentration and converts to electrical signal. The module sends signal to gas controller and outputs alarm trigger signal when concentration exceeds preset safe threshold.
Installation Requirements Disconnect power supply before installation. Choose proper installation height and position based on gas density. Fix sensor module with mounting bracket. Wire field cable following official wiring schematic. Power on, perform gas calibration and self-test procedure.
