Oxygen Sensors (O2)
Oxygen makes up 21% of the atmosphere by volume. This is halfway between 17% (below which breathing for un-acclimatised people becomes difficult) and 25% (above which many organic compounds are highly flammable). The element and its compounds make up 49.2% by mass of the Earth’s crust, and about two-thirds of the human body.
Accurate measurement of Oxygen is core to Alphasense’s portfolio, be it require for safety, medicine, air quality or specialist processes.
Alphasense Oxygen Sensors (O2 sensors) have proved the test of time as cost effective, low cost and robust in a host of applications. Unlike partial pressure oxygen sensors, our design has good pressure and temperature dependence, making it the best choice in safety applications. Our lead free O2 sensor range have a significantly increased lifetime over a lead based sensor – minimising the likelihood of sensor leaks and making mid-contract servicing a thing of the past.
Alphasense O2 Sensors
Our O2 sensors are available in three sizes:
A: 20mm diameter, the industry standard size for portable gas detectors
C: 20mm diameter, extra height allows additional filter material when measuring combustion gases
G: Miniature, proven long-term performance. The sensors are designed for the next generation of portable gas detectors. Part of the Alphasense ‘D‘ family.
