The relationship between the measured variable (temperature) and the resistance<br />
value is shown on a graph.<br />
The designation of the various PTC sensor elements is standardized and<br />
comprises:<br />
a) the material of the sensor element<br />
b) its resistance at 0 °C<br />
e.g. Ni 1000<br />
Nickel sensor element<br />
1000 Ω resistance at 0 °C.<br />
e.g. Pt 100<br />
Platinum sensor element<br />
100 Ω resistance at 0 °C.<br />
NTC sensors<br />
The characteristic curve of the NTC sensor<br />
is not linear.<br />
The measuring ranges are defined by the<br />
manufacturer.
