Note: If the exhaust gas temperature of 850 º C is exceeded,the heater power must be switched off. In this case the accuracy ofthe sensor signal is limited.Operating temperatureof the sensor housing hexagonat the cable glandat the connection cableat the connectorMaximum current load of lambda = 1 Nernst cellMaximum pumping current into pump cellfor rich gas signalfor lean gas signalHeater ElementNominal supply voltage, test voltageMaximum permissible effective heater voltage at sensor element temperature of< 900 º Cshort time < 200 hourscontinuousMinimum frequency of heater voltage controlat supply voltage (peak) < 16 Vat supply voltage (peak) < 28 VNominal heating power for exhaust gas = 350 º C & exhaust gas flowspeed of ~ 0.7 m/sec at 9 V heater voltageInsulation resistance between heater and sensor connection-40…+ 100 º C< + 980 º C(max 250 h in 10 min intervals)< + 570 º C< + 200 º C< + 150 º C< + 120 º C< 10 uA> - 9 mA< 18 mA9 V< 13 V< 12 V> 2 Hz> 10 Hz~10 W> 30m ohmsInitial heater voltage is dependent on start temperature of sensor; nominal values at- 40 º C 7.4 V- 10 º C 7.8 V+ 20 º C 8.2 V+ 50 º C 8.6 VMaximum heater voltage increase during warm-up phaseNominal heater cold resistance at ambient temperature for new sensor,including cable and connectorat 20 º Cat - 40 º C< 0.4 V/sec3.2 ohms2.1 ohmsBosch Automotive Aftermarket 2009 | 2010
