Factory making Outdoor Co2 Sensor - Integrated ASIC AFE Single Channel NDIR Gas Sensor CH4 Gas Detector-SSG11DF33G1 – Sunshine Detail:
General Description
The SSG11DF33G1 family of integrated thermopile sensor for NDIR (Infrared gas detection) is a single channel thermopile sensor having an output signal voltage directly proportional to the incident infrared (IR) radiation power. An infrared narrow band pass filter in front of the sensor makes the device sensitive to target gas concentration. The SSG11DF33G1 comprising a new type CMOS compatible thermopile sensor chip features good sensitivity, small temperature coefficient of sensitivity as well as high reproducibility and reliability. An ASIC AFE (Analog Front End) chip is integrated with the thermopile sensor, providing 1000 gain for the small voltage output of thermopile sensor. A input offset voltage is also added in the sensor input. The sensor output voltage can be directly converted by ADC, which elimates the precision Zero-Drift amplifier and DC-DC circuit. A high-precision thermistor reference chip is also integrated for ambient temperature compensation.
SDG11DF33 NDIR CH4 sensor detect Methane（CH4）concentration from 0 to 100% based on NDIR technology which is superior than thermal catalysis and thermal conductivity technology. It has advantages of convenient operation, accurate measurement, reliable operation, simultaneous output of voltage and serial port, and double beam design. It meets the different requirements of industrial field and laboratory measurement, and is widely used in gas detection and analysis in petrochemical, chemical, coal mine, medical and laboratory fields.
It has the features of:
- NDIR technology with long lifespan and full measurement range
- Internal full range temperature compensation
- Diffusion sampling, stable performance
- High precision
- Compact size, fast response
- Corrosion prevention
- Easy install and less maintenance
- Compatible with digital and analog voltage signal output
