Specification

SENSOR SPECIFICATION
Measurement technology	High-performance NDIR
Measurement Range	0 - 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	<± 1000 ppm
Long-term zero drift/month	±500 ppm
Response to 0-90% change in RH at 20 °C (in target gas)	+0.1% Vol (at 5% Vol)
MTBF (lamp dependent only)	>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 - 95% RH, non-condensing
SIGFOX SPECIFICATION
Sigfox zones	select RC1-RC2-RC3c-RC4
