Specifications

Sensor specifications:
- Measurement technology: High-performance NDIR
- Measurement Range: 0 to 100% LEL Flammable Gas, equivalent to 0-5% Vol of Methane (CH4)* for the C3H8 gas application, please consult us before ordering
Maximum response time (T90)< 40s
- Resolution: 500 ppm (at 5% Vol). The resolution will vary with gas concentration due to the non-linear response to the target gas, therefore the best resolution will be at the low concentrations and will get worse as the concentration increases.
- Maximum deviation from linearity: +/- 0.1% vol
- Maximum variation of zero: from -20 to 55 C +/- 30 ppm/C
- Maximum non-reproducibility of zero at 20 C: +/- 500 ppm
- Maximum non-reproducibility of sensitivity at 20 C: less than +/- 1000 ppm
- Long-term zero drift/month: +/- 500 ppm
- Response to 0 to 90% change in RH at 20 C (in target gas): 0.1% Vol (at 5% Vol)
- MTBF (lamp dependent only): more than 10 years
- Vibration: Complies with EN 60079-29-1
- Sensor Operating Temperature Range: -20 to 60 C
- Operating Pressure: 700kPa to 1300kPa
- Operating Humidity Range: 0 to 95% RH, non-condensing
Sigfox specifications:
- Sigfox zones: RC1-RC2-RC4
