NXP Semiconductors KTY81 series Silicon temperature sensors 5. Limiting values Table 5. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
Symbol Parameter Conditions Min Max Unit
Isen(cont) continuous sensor current in free air; Tamb = 25 °C - 10 mA in free air; Tamb = 150 °C - 2 mA Tamb ambient temperature −55 +150 °C
6. Characteristics Table 6. Characteristics
Tamb = 25 °C; in liquid; unless otherwise specified.
Symbol Parameter Conditions Min Typ Max Unit
R25 sensor resistance Isen(cont) = 1 mA KTY81/110 990 - 1010 Ω KTY81/120 980 - 1020 Ω KTY81/121 980 - 1000 Ω KTY81/122 1000 - 1020 Ω KTY81/150 950 - 1050 Ω KTY81/210 1980 - 2020 Ω KTY81/220 1960 - 2040 Ω KTY81/221 1960 - 2000 Ω KTY81/222 2000 - 2040 Ω KTY81/250 1900 - 2100 Ω TC temperature coefficient - 0.79 - %/K R100/R25 resistance ratio Tamb = 100 °C and 25 °C 1.676 1.696 1.716 R−55/R25 resistance ratio Tamb = −55 °C and 25 °C 0.480 0.490 0.500 ∆R25 drift of sensor resistance at 10000 h continuous 25 °C operation; Tamb = 150 °C KTY81/1 series - 1.6 - Ω KTY81/2 series - 3.2 - Ω τth thermal time constant in still air [1] - 30 - s in still liquid [1] - 5 - s in flowing liquid [1] - 3 - s [1] The thermal time constant is the time taken for the sensor to reach 63.2 % of the total temperature difference. For example, if a sensor with a temperature of 25 °C is moved to an environment with an ambient temperature of 100 °C, the time for the sensor to reach a temperature of 72.4 °C is the thermal time constant.
