Optical Oxygen Gas Sensor

The FDO2 oxygen sensor is a factory calibrated, robust, accurate, fast response, long lasting and almost maintenance free oxygen sensor.

The optical measurement is based on a propriatary luminescent sensor dye from PyroScience, which is sensitive to oxygen partial pressure. This principle is very robust and shows virtually no interferences to other gases. For typical indoor environmental conditions a 10 year operating life is expected.

INTRODUCTION

Key features

◆ Factory calibration

◆ Fast response time (t63 <2 sec)

◆ Low drift (typ. < 1% O2/year at 21% O2)

◆ Simple 1-point user calibration (e.g. at air)

◆ Wide measuring range (0 -100% O2, up to 200% O2 on request)

◆ Highly hydrophobic sensing surface (water droplets do not disturb the measurement)

◆ Simple communication interface (UART, command or broadcast mode)

◆ Linearity over the full oxygen range and sensor lifetime
