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, 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.
The temperature factor kT can be derived from this:
The temperature at the sensor can be calculated from the change in the sensors
resistance from the following equation, which approximates the characteristic curve.
