Characteristics[1]The thermal time constant is the time taken for the sensor to reach % of the total temperature difference. For example, if a sensorwith a temperature of 25 C is moved to an environment with an ambient temperature of 100 C, the time for the sensor to reach atemperature of C is the thermal time valuesIn accordance with the Absolute Maximum Rating System (IEC 60134).SymbolParameterConditionsMinMaxUn itIsen(cont)continuous sensor currentin free air; Tamb=25 C-10mAin free air; Tamb= 150 C-2mATambambient temperature 55+150 CTable C; in liquid; unless otherwise resistanceIsen(cont)=1mAKTY81/110990-101 0 KTY81 /120980-1020 KTY81 /121980-1000 KTY81 /1221000-1020 KTY81 /150950-1050 KTY81 /2101980-2020 KTY81 /2201960-2040 KTY81 /2211960-2000 KTY81 /2222000-2040 KTY81 /2501900-2100 TCtemperature ratioTamb= 100 C and 25 55/R25resistance ratioTamb= 55 C and 25 R25drift of sensor resistance at25 C10 000 h continuousoperation.
