The graphs below show the variation in output with temperature for this type of sensor. The results are shown in the graphs as a mean for a batch of sensors, along with confidence intervals corresponding to ±3 times the standard deviation. The sensitivity dependence is expressed as a percentage of the signal at 20 °C. Sensitivity Temperature Dependence 120% Output (referenced to 20 °C) 110% 100% 90% 80% 70% Mean 60% +3SD -3SD 50% -20 -10 0 10 20 30 40 50 Tem perature (°C) The data contained in this document is for guidance only.
