When the temperature sensor is operated with long supply leads, it should be protected through the parallel
connection of a > 10 nF capacitor to prevent damage to the sensor through induced voltage peaks.

KT- and KTY-Series Temperature Sensors
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.
