Introduction: HK-7100A/HK-7101 combustible gas detector is a kind of instrument independently researched and developed by our company to monitor the concentration of combustible gas in the field environment in the control room. It can be widely used in petrochemical, oil and gas storage and transportation, chemical industry, oil depot , Liquefied gas stations, gas-fired boiler rooms and other areas where flammable and explosive hazardous gases exist. Features: 1. Five detection principles cover almost all flammable and toxic gases; 2. Five kinds of detection principle detector host universal, hundreds of gas and range of smart sensors are fully compatible, fully interchangeable; 3. It is very convenient to replace the pluggable smart sensor, the host automatically recognizes the measuring principle of the sensor, the type of gas measured, the range, etc.; 4. The sensor supports hot-plugging, plug and play, sensor failure self-diagnosis; 5. Advanced 32-bit embedded microcontroller technology, data processing and rapid; 6. Can use centralized bus power supply, can also use independent area power supply, the choice is more convenient; 7. Wide temperature, high brightness OLED display, easy reading in direct sunlight and dark environment, adapt to harsh temperature and lighting environment; 8. Chinese and English bilingual menu, friendly user interface; 9. Unique magnetic pen and infrared remote control operating mode (infrared remote control is optional), user-friendly operation; 10. The advanced SMT patch process reduces the volume of the product and improves the reliability of the product. Technical Parameters: 1. Infrared measuring principle Display: OLED display in English and Chinese, and one, two, fault alarm indicator Detection gas: flammable/toxic gas such as HC, CO2 Sampling method: natural diffusion Resolution: 1%FS Response time (T90): ≤15s Ambient temperature: (-40-60)°C Signal transmission: (4-20) mA, (4-20) mA+RS485 bus optional Operating voltage: DC (18-30)V (controller bus power or independent area power supply) Connection method: three-wire or four-wire Power: ≤5 W Protection class: IP66 Operation method: magnetic pen, infrared remote control Measuring principle: infrared Measurement range: HC:(0-100)%LEL CO2:(0-5000)×10-6,(0-2)%,(0-5)%,(0-100)% optional Measurement error: ±3%FS Alarm concentration: Two-level alarm and fault relay, one and two alarm concentrations can be set Atmospheric pressure: (86-106)kPa Transmission distance: (4-20)mA: ≤1000m (2.5mm2) RS485 bus: ≤1200m (2.5mm2) Explosion-proof mark: Exd II CT6Gb Implementation of the standard: GB15322.1-2003 2. Catalytic combustion measurement principle Display: OLED display in English and Chinese, and one, two, fault alarm indicator Gas Detection: Combustible Gas Sampling method: natural diffusion Alarm indication: A primary alarm, secondary alarm, fault alarm indication Resolution: 1% LEL Response time (T90): ≤10s Ambient temperature: (-40-70)°C Signal transmission: (4-20) mA, (4-20) mA+RS485 bus optional Operating voltage: DC (18-30)V (controller bus power or independent area power supply) Connection method: three-wire or four-wire Power: ≤5 W Protection class: IP66 Operation method: magnetic pen, infrared remote control Measuring principle: Catalytic combustion Measuring range: (0-100)%LEL Measurement error: ±3%LEL Alarm concentration: Two-level alarm and fault relay, one and two alarm concentrations can be set Atmospheric pressure: (86-106)kPa Transmission distance: (4-20)mA: ≤1000m (2.5mm2) RS485 bus: ≤1200m (2.5mm2) Explosion-proof mark: Exd II CT6Gb Implementation of the standard: GB15322.1-2003
