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 ° Cto+ 150 °C. The
temperature sensing element is an n-conducting silicon crystal in planartechnology. The
gentle curvature of the characteristic,

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.
