Technical Specifications Power Supply: 24V DC Operating Temperature: -40℃ ~ 70℃ Mounting: Wall or pipe bracket mounting Signal Output: 4-20mA analog or digital bus signal Protection Grade: IP66
Functional Features Continuous real-time gas concentration detection. Raw sensor signal conditioning and standard signal output. Built-in self-diagnosis for sensor degradation and circuit fault. High anti-electromagnetic interference performance. Stable operation under high humidity and dusty atmosphere. Adjustable alarm thresholds for different working sites.
Application Scenarios Refinery and petrochemical plant gas safety monitoring. Chemical processing plant hazardous gas detection. Power plant, oil and gas station fire and gas protection. Honeywell 05704 gas detection system spare transmitter. Explosion-proof industrial hazardous area safety monitoring.
Performance Parameters Response characteristic: Fast response to target gas Measurement stability: Minimal span and zero drift Environmental tolerance: Tolerate dust, moisture and temperature change Fault diagnosis: Automatic sensor failure detection and alarm
Material Composition Housing: Explosion-proof cast aluminum alloy Sensing element: Industrial gas sensitive component Internal PCB: High reliability signal processing circuit board
Structural Characteristics Integrated explosion-proof sealed housing assembly. Gas diffusion inlet for ambient gas sampling. Cable gland port for power and signal cable entry. Metal mounting bracket for wall or pipe installation. Independent internal compartment for sensor and electronic circuit.
Working Principle Ambient gas enters through diffusion inlet and interacts with sensing element to produce raw electrical signal. The internal circuit conditions the signal and converts it to standard output signal, transmitting measurement value to controller and activating alarm upon over-limit concentration.
Installation Requirements Disconnect power before installation and wiring. Select installation position based on gas density and air flow direction. Fix transmitter with metal mounting bracket. Complete wiring strictly following Honeywell wiring schematic. Power on, perform gas calibration and full self-test.
