The temperature sensing element is an n-conducting silicon crystal in planar technology. The gentle curvature of the characteristic, RT = f (TA), is described as a regression parabola in the following expressions. The resistance of the sensor can be calculated for various temperatures from the following second order equation, valid over the temperature range − 30 °C to + 130 °C. R T = R 25 × ( 1 + α × ∆ T A + β × ∆ T A2 ) = f ( T A ) with: α = 7.88 10− 3 K− 1; β = 1.937 10− 5 K− 2 The temperature factor kT can be derived from this: RT k T = ------- = 1 + α × ∆ T A + β × ∆ T A2 = f ( T A ) R 25 The temperature at the sensor can be calculated from the change in the sensors resistance from the following equation, which approximates the characteristic curve. α2 – 4 × β + 4 × β × k T – α T =  25 + --------------------------------------------------------------------- ° C   2×β Data Sheet 4 2000-07-01 KT- and KTY-Series Temperature Sensors Table 1 Spread of the Temperature Factor kT TA °C − 50 − 40 − 30 − 20 − 10 0 10 20 25 30 40 50 60 70 80 90 100 110 120 130 140 150 1) Normalising point kT min. 0.506 0.559 0.615 0.676 0.741 0.810 0.883 0.960 1.039 1.119 1.204 1.291 1.383 1.478 1.577 1.680 1.786 1.896 2.010 2.093 2.196 typ. 0.518 0.570 0.625 0.685 0.748 0.815 0.886 0.961 1.0 1) 1.040 1.123 1.209 1.300 1.394 1.492 1.594 1.700 1.810 1.923 2.041 2.128 2.235 1.041 1.126 1.215 1.308 1.405 1.506 1.611 1.720 1.833 1.951 2.072 2.163 2.274 max. 0.530 0.581 0.635 0.694 0.755 0.821 0.890 0.962 Data Sheet 5 2000-07-01 KT- and KTY-Series Temperature Sensors Sensor Resistance RT = kT × R25 = f (TA) Sensor Resistance RT = kT × R25 = f (TA) IB = 1 mA; Example: R25 = 2000 Ω IB = 1 mA; Example: R25 = 1000 Ω Typical Dependence of Sensor Resistance on Supply Current Example: KTY 10-6 in oil at TA = 25 °C Typical Dependence of Sensor Resistance on Supply Current Example: KTY 21-6 in oil at TA = 25 °C Data Sheet 6 2000-07-01 KT- and KTY-Series Temperature Sensors Typical Deviation of Sensor Resistance from the Basic Resistance R25 (IB = 1mA) Versus Supply Current Example: KTY 10-6 in oil at TA = 25 °C Typical Deviation of Sensor Resistance from the Basic Resistance R25 (IB = 1mA) Versus Supply Current Example: KTY 21-6 in oil at TA = 25 °C Typical Relationship of the Temperature Factor RT k T = ----- = f ( T A ) R 25 Typical Relationship of the Temperature Factor 1 dR T TCT = ---- × ------- = f ( T A ) R T dT A Data Sheet 7 2000-07-01 KT- and KTY-Series Temperature Sensors Definition of the Thermal Time Constant τ ∆TA = TA2 − TA1; τ = t1 − t0 Thermal Time constant τ=5s Peak Current in Air Peak Current in Air R25 = 2000 Ω; I = f (TA) ^ R25 = 1000 Ω; I = f (TA) ^ Data Sheet 8 2000-07-01 KT- and KTY-Series Temperature Sensors Package Outlines Modified TO-92 1 1.6 -0.1 2 KT 100 KTY 10-x 5.2 -0.2 0.5 ±0.2 5.2 14.5 -1 4.2 -0.2 1.5 +0.2 0.6 +0.02 0.4 +0.05 2.54 Weight approx. 0.25 g 0.4+0.05 GPD05636 TO-92 Mini 2.1-0.2 1 1.9-0.2 2 (1.9) 1.7-0.2 KT 110, KT 210 KTY 11-x, KTY 2x-x 0.928 0.5 ±0.1 0.4 ±0.1 14.1 0.9 ±0.1 Weight approx. 0.02 g 0.2 +0.07 -0.03 Sorts of Packing Package outlines for tubes, trays etc. are contained in our Data Book “Package Information”.
