DATA SHEET Zirconia O Sensors 2 OXY-Flex Oxygen Analyser FEATURES High accuracy linear output Externally triggered automatic or manual calibration Can be calibrated in fresh air (20.7% O ) or to any 2 other known O concentration 2 Selectable output filtering allows adaptive, fast and dynamic or slow and stable output Housing Supply Gas Temp Digital Analogue Response Voltage Output Output Time BENEFITS OUTPUT VALUES 2 1 Oxygen range (analogue output) 0.1 25% O 2 Cycling 3.3V logic output allows direct monitoring of the DC 1 or 0.1 100% O 2 O sensor pump cycle for diagnostic purposes 2 1 Oxygen range (RS232 output) 0.1 and 100% O 2 No reference gas required 3, 4 Accuracy after calibration 1% O 2 3 Repeatability after calibration 0.5% O 2 Output resolution TECHNICAL SPECIFICATIONS Analogue 420mA 0.01mA Supply voltage 24V 10% Analogue 010V 0.01V DC DC Supply current 500mA max. at 24V Digital RS232 0.01% O DC 2 Digital output RS232 Response time < 15s Analogue output 420mA load 600 max. Warm up time (prior to sensor operation) 60s or 010V load 10k min. Output stabilisation time ~ 180s DC Housing temperature limits Storage: -10C to +85C Operating: -10C to +85C Permissible gas temperatures (probe tip) Need help Ask the expert Standard: -100C to +250C Tel: + 44 (0)1236 459 020 High: -100C to +400C and ask for Technical Gas flow rate 0 to 10 m/s Permissible acceleration Repetitive 5g Incidental 30g 1) Prolonged operation below 0.1% O can damage the sensing element. 2 2) Range selectable by altering the position of the jumper links on the PCB refer to PCB Layout on page 3. NOTES 3) Assuming barometric pressure (BP) remains constant. 4) As the O sensor measures the partial pressure of oxygen (PPO ) within the measurement gas deviations in the BP from 2 2 that present during calibration will cause readout errors proportional to the change. EG. if the sensor reads 21% O at 2 1013.25mbar and the BP increases by 1%, the sensor readout will also increase by 1% to 21.21% O . 2 OUTLINE DRAWING AND MOUNTING INFORMATION All dimensions shown in mm.
