Methane Gas Detection Transmitter for Safety Monitoring in Coal Chemical Gasification Furnace Areas - Working Principle
Methane gas detection transmitters usually use catalytic combustion sensors or infrared sensors to output electrical signals by detecting methane concentration, which are converted into 4-20mA, RS485, or Modbus signals after circuit processing. In safety monitoring of coal chemical gasification furnace areas, methane gas detection transmitters support remote calibration and fault self-diagnosis and can be connected to PLC, DCS, and gas alarm control systems. The transmitter has an explosion-proof housing and high protection rating, suitable for high-temperature, high-dust, and corrosive environments in coal chemical industries.
Methane Gas Detection Transmitter for Safety Monitoring in Coal Chemical Gasification Furnace Areas - Application Scenarios
Methane gas detection transmitters are widely used in gasification furnace areas, shift conversion areas, purification areas, and compression plants in coal chemical industries. In safety monitoring of coal chemical gasification furnace areas, methane gas detection transmitters can be installed near gasification furnaces, pipeline valves, and personnel inspection passages. The transmitter can be linked with exhaust fans, shut-off valves, and fire protection systems to achieve automatic handling. For large coal chemical plants, methane gas detection transmitters can form a multi-point monitoring network and upload data uniformly to the control room.
Methane Gas Detection Transmitter for Safety Monitoring in Coal Chemical Gasification Furnace Areas - Technical Advantages
