EC4-50-CLO2 Amphenol

EC4-50-ClO2 Electrochemical Sensor PERFORMANCE OUTLINE Range ...................................................................0 - 50 ppm Sensitivity (see note)........................ 220 - 580 nA/ppm ClO2 Zero in air at 20 C......................................<0.09ppm ClO2 Resolution......................................................0.05 ppm ClO2 Expected lifetime ....................................................... 2 years Linearity ...................................................linear across range Response time, t90....................................................... <60 s Long-term output drift......... <2% change in output per month Operating circuit............... see Electrochemical Toxic Sensor Application Note Note: This output current is negative. This is because the sensor reaction is a reduction of the target gas. OPERATING CONDITIONS Temperature range ...........................................-20 to +50 C Operating humidity................15 - 90% RH (non-condensing) Pressure range ..................................90 - 110 kPa (nominal) Operating circuit............... see Electrochemical Toxic Sensor Application Note Applied potential ..............................................................0 V Storage life........... 6 months in original packaging (0 - 25 C) PHYSICAL CHARACTERISTICS Label colour ...................................................................silver Weight............................................................................... 6 g Dimensions ...........................................................see outline Shelf life.................................................................. 6 months This device is designed to be RoHS compliant.
