Abstract [en]

Herein pressure modulation is proposed as a method to increase the resolution as well as to eliminate long term drift of NDIR gas sensors. Measurements are presented that verifies the theoretical predictions of possibility to drift compensation and resolution improvement. The resolution is increased 8.6 times when the pressure is changed from atmospheric to 900 kPa. The method can be applied to existing sensors for both resolution improvement and drift compensation.
