Anti-interference design for industrial electromagnetic noise. Stable performance under high humidity and dusty environment. On-site configurable alarm set points.
Application Scenarios Petrochemical and refinery gas safety monitoring. Chemical factory toxic and flammable gas detection. Oil & gas terminal and power station safety protection. Honeywell 05704 gas detection system maintenance spare transmitter. Explosion-proof hazardous area gas monitoring subsystem.
Performance Parameters Gas response: Fast response for target gas Signal drift: Low zero drift under temperature cycling Environmental resistance: Adapt to dusty and humid working condition Self-test function: Automatic fault alarm for sensor failure
Material Composition Housing: Explosion-proof cast aluminum alloy Sensing element: Industrial gas sensitive sensor Internal PCB: Industrial signal conditioning circuit board
Structural Characteristics Sealed explosion-proof metal housing. Gas diffusion sampling inlet. Cable gland port for field wiring. Metal mounting bracket. Separated internal chamber for sensor and electronic assembly.
Working Principle Ambient hazardous gas diffuses into the sensor cavity and generates corresponding electrical signal. The on-board circuit processes and converts raw signal into standard transmission signal, then transmits to central controller and triggers alarm if concentration exceeds threshold.
Installation Requirements Cut off power before installation and wiring operation. Choose installation position according to gas relative density. Secure transmitter by mounting bracket. Wire power and signal cable following official wiring diagram. Power on, calibrate sensor and run self-test procedure.
