Features: 1. Advanced embedded MCU technology 2. The current signal transfer form, greatly enhance the signal transmission distance 3. Can be used in a centralized bus power supply, independent regional power supply may be adopted 4. LED digital tube display, can in industrial environment within the range of lower explosive limit on combustible gas monitoring and alarm, real-time transmission and transmit gas concentration information to the controller 5. Unique magnetic pen operation mode 6. The impact of high concentration of gas automatic protection function 7. The use of advanced catalytic combustion type sensors, performance is stable, sensitive and reliable, good resistance to toxic and strong anti-jamming capability 8. When the sensor failure or due to aging may lose function, the detector can automatically identify and report to the police (lamp), effectively avoid the omission 9. Advanced SMT technology and the integration of design, improves the performance and reliability Technical indicators: Display: LED digital tube display, can real-time display current monitoring the concentration of the gas at the scene, and the upper limit and lower limit, fault alarm indicator Detection of gas: combustible gas Sensor principle: catalytic combustion type Sampling methods: natural diffusion Measuring range: (0 ~ 100) % LEL In distinguishing rate: 1% LEL Instruments: of error of plus or minus 3% LEL Response time: no more than 30 s (25 ℃) Alarm concentration: two levels of alarm, a, the concentration of the secondary alarm can be set Environmental humidity: no greater than 93% RH (40 ℃), no condensation The atmospheric pressure (86 ~ 106) kPa Signal transmission: (4 ~ 20 mA) or CAN bus Transmission distance: no more than 1000 m was (2.5) or 10 km Working voltage: dc (24 + 6) V (controller bus power supply or independent regional power supply) Attachment: three wire or four wire system Power: no larger than 2 w Storage temperature: (- 40 ~ 85 ℃) Explosion-proof marks: Exd II CT6 Protection grade: achieve IP66
