KT- and KTY-Series Temperature Sensors
General Technical Data: KT- and KTY-Series Temperature Sensors These temperature sensors are designed for the measurement, control and regulation of air, gases and liquids within the temperature range of - 50 C to + 150 C. 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 x ( 1 + x T A + x T A2 ) = f ( T A )
with: = 7.88 10- 3 K- 1; = 1.937 10- 5 K- 2 The temperature factor kT can be derived from this:
RT k T = ------- = 1 + x T A + x 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. 2 - 4 x + 4 x x k T - T = 25 + --------------------------------------------------------------------- C 2x
