The SGX sensors supplies a wide range of combustible gas sensors (pellistors) working on the catalytic oxidation principle. The VQ21T Series are members of the VQ21 range of high power, low voltage poison resistant detectors for general purpose application particularly for fixed point systems where the consideration of power consumption is not an overriding factor. It may be used to detect most flammable gases and vapours and, in particular, can detect methane in air mixtures with concentrations from 0.1% up to 5% (100%LEL).

Expected operating life >5 years

Bridge Supply voltage 2.0 + 0.1 V

Sensor Power consumption 750 mW max

Linearity linear up to 3% CH4

Storage temperature +10C to +25 C

Operational temperature -40C to +70C
