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 planar technology. The

gentle curvature of the characteristic,

T = 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

T 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.
