APPLIED SENSING TECHNOLOGIES % Oxygen Sensor Model: SRX-CT22A SRX-CT22A Oxygen Sensor is a galvanic type micro fuel cell speciﬁc to oxygen. Proprietary electolyte formulation ensures full utilization of Pb anode, thus providing longer life without signal drift and minimizing periodic calibration requirement. This sensor is similar to R21A except mV output in air. Sensor is designed, developed and manufactured in the USA SRX-R22A replaces: Teledyne R-22A Envitec 00A101 City Technology AO2 Speciﬁcations* Sensor Technology Measuring Range Signal Output¹ Response Time T90 Accuracy ² Drift ² Linearity Repeatability Temperature Coefﬁcient Operating Temperature Recommended Storage Temperature Recommended Flow Rate Humidity Non-Condensing2 Expected Life³ Recommended Storage Warranty4 Electrical Connections Front Galvanic Type Micro Fuel Cell 0 to 100 Percent Oxygen 7-13 mV 6 seconds +/- 1% of signal < 2% +/- 1% +/- 0.5% NONE - signal output is temperature compensated 0 to 40°C 5 to 35°C - Intermittent exposure upto 50o C acceptable 0.5 - 5 SCFH 0 - 98% RH 36 months 6 months 12 months 3-PIN Molex M16 x 1 thread Note: SRX-CT22A is packaged in a polyethylene bag. Do not expose sensor to temperatures above 50o C for extended period of time. Failure to do so may have negative impact on its performance and life. 1. Signal Output measured in air at 25°C, atmospheric pressure. 2. At constant temperature and pressure; for each %RH increase, O2 signal will drop equivalent to 0.03% oxygen. 3. At ambient temperature and pressure, and oxygen content less than 21%. 4. AST warrants the sensor for 12 months to be free from defects in materials and workmanship. AST will not be held liable for sensor damaged due to customer neglect. * Speciﬁcations are validated during design and are subject to change without notice.
