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 planartechnology. 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.
The temperature factor
k
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.
