KTY thermal sensors

Due to their non-linear temperature resistant behaviour, KTY sensors are rather limited in their accuracy and must be calibrated with additional electronics for sufficient accuracy.
As a result of this, the temperature range for KTY sensors is really quite modest.

The greatest disadvantage of KTY sensors is their sensitivity to electrostatic discharge (ESD).
The sensors can be slightly damaged by external voltage pulses. In contrast, the temperature coefficient of KTY sensors is around twice as high in comparison to PT100. The evaluable effective signal is less vulnerable to disturbances from the sensor environment. When using KTY sensors, it is important to note that these are polarised building elements.

eaw Relaistechnik offers the installation of NTC, PTC, KTY, PT100, PT500 or PT1000 thermistors within our trusted housing range for the ½-inch thermal switch series. With this solution, you have the option to replace traditional bimetallic thermostats with temperature sensors featuring NTC or PTC elements as thermistors immediately without having to change the design of your tools or your construction documentation.

Material und temperature ranges

  • Silicon spreading resistance with 2 metallic poles
    (silicon coating typically 100 µm thick)
  • Limited temperature range of approx. 200 Kelvin

Different rated resistances for different rated temperatures

  • KTY83           RN=1000 Ω at 25°C
  • KTY84           RN=1000 Ω at 100°C

Basic types are further subdivided in terms of the level of the tolerance of the rated resistances as well as the position of the tolerance bandwidths.
