Page 6: Measuring Principle
103-12-306-003-EH-0412.pdf 4 Measuring Principle The sensor module is a complete solution for measuring oxygen within the range of 0,1...25%. The sensor and the electronics are united on one board. The electronic amplifies the sensor signal and puts it out as logarithmic current output signal 4…20mA ( according IEC 60381 ) Principle sketch of the O Limiting-current sensor The zirconia is pervious to oxygen ions when heated up to approx.

103-12-306-003-EH-0412.pdf 5 Operation Start 5.1 Mechanical Installation The dimensions of the board are 75 x 40 x 28mm. On every corner are mounting wholes with a diameter of 3,5 mm. The board holds highly sensitive switches. While installing make sure that no components get damaged mechanically Attention 5.2 Pneumatical Connections...

103-12-306-003-EH-0412.pdf 5.3 Electrical Connections 5.3.1 Supply The module gets supplied with 7...28VDC through the clamps 1 (+) and 2 (-), approx. 200mA (24VDC). 5.3.2 Analog Output For the output signal the clamps 3 (+) and 4 (-) can be used. 6 Environment Condition Also see item 11 in our specifications, especially for the temperature and humidity range (non- condensing).
Page 9: Gas Flow
103-12-306-003-EH-0412.pdf 8 Gas Flow Heed the following points: The flow should not be smaller than 0,1 and not larger than 3,0l/min. Optimal 0,5l/min We recommend to use a suitable filter, since the gas flow can contaminate the sensor, which will shorten its life span considerably. Avoid condensation (H O) inside the sensor housing.

Page 11: Important Advice
103-12-306-003-EH-0412.pdf 10 Important Advice 10.1 Restrictions Don’t separate the sensor from the circuit board. Don’t change the length of the lead wires. Don’t operate this sensor in a high oxygen concentration (>25% O If the sensor is exposed to such high oxygen concentration, limited output over 20mA will be observed.
