4 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,r T =f(t A ), 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. 2 R T = R T A + T A = f T A with: K 1 ; K 2 The temperature factork T can be derived from this: k T R T R 25 2 = = 1+ T A + T A = f T A The temperature at the sensor can be calculated from the change in the sensors resistance from the following equation, which approximates the characteristic curve k T 25 T = C 2 Data Sheet
