O2-A3 Oxygen Sensor (O2 Sensor)

O2-A3 Oxygen Sensor O2 Sensor Description Alphasense Oxygen sensors use capillary flow control. Unlike partial pressure oxygen sensors, they have good pressure and temperature dependence, making them the best choice in safety applications. Standard galavanic sensors use lead for greatest reliability but fixed lifetime. O2-A3 Oxygen Sensorsize: 20mm diameter, the industry standard size for portable gas detectors O2-A3 Oxygen Sensor O2 Sensor Specifications * Output: 60 to 85 μA @ 22'C, 20.9% O2 * Response time t90 : < 15 (s) from 20.9% to 0% O2 * Operating life: > 36 months * Temperature range : -30 to 55 'C * Pressure range : 80 to 120 kPa * Humidity range : 5 to 95 % rh continuous * Height : 17.4 mm (including foam ring) * Weight: < 16 g
