Zirconia o2 sensors Miniature series The miniature zirconium dioxide oxygen sensors can be pcb mounted and are used when measuring ambient gas with the complete sensor immersed in the atmosphere which is to be measured. Features * zirconium dioxide (zro2 ) sensing elements * long life, non-depleting technology * integral heating element * high accuracy * requires an external interface board to operate Benefits * no reference gas required * no need for temperature stabilisation * pcb mountable Technical specifications Heater voltage Standard response sensor: 4v dc â± 0.1v dc (1.7a) Standby: 1.65v dc (0.7a) Fast response sensor: 4.35v dc â± 0.1v dc (1.85a) Standby: 2v dc (0.85a) Pump impedance at 700'c: < 6k Permissible gas temperature: -100'c to +250'c Gas flow rate : 0 - 10 m/s Repetitive permissible acceleration: 5g Incidental permissible acceleration: 30g Output values Oxygen pressure range: 2mbar - 3bar max Accuracy: 5mbar max Internal operational temperature: 700'c Response time (10 - 90% step) Standard response sensor:
