Zirconia O2 Sensors Probe Series - Short Housing The Probe Range of zirconium dioxide oxygen sensors are available in three lengths. Suitable for aggressive and polluted applications such as boiler exhausts. Longer probes are an ideal solution for thicker walled, insulated flue pipes. 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 * Compact enclosure TECHNICAL SPECIFICATIONS Heater voltage Operating (standard response) 4V DC ± 0.1V DC (1.7A) Standby 1.65V DC (0.7A) Operating (fast response) 4.35V DC ± 0.1V DC (1.85A) Standby 2V DC (0.85A) Pump impedance at 700'C < 6kΩ 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 < 15s Fast response sensor < 4s Warm up time (prior to sensor operation) 60s Warm up time (from standby) 20s Output stabilisation time ~ 180s
