Figure 2 TemperaturePerformance Figure 3 Pressure StepPerformance Figure 2 shows the variationof output caused by changes in temperature in 20.9% oxygen.All capillary oxygen sensorsshow a change in signal with temperature, and the very repeatable 95% confidence intervals for the O2-A3 are shown. Figure 4: shows how the Familyof Alphasense oxygen sensors respond to a 10kPa pressure step.Sensors with lower outputsand longer lifetime show greater output transients, but are predictable and repeatable.
o C Figure 3 shows how a 25 kPapressure step change causes a signal transient that decays reproducibly. Negative pressure changes cause a negative transient.The small shift in final outputis less than 10% of the pressure change, so 10kPa pressure step shifts output by less than 1% (<0.2% oxygen).
