| Summary: | The most exact temperature measurement can be made by using platinum sensors.
Temperatures from -254.3°C up to +850°C can be measured with Pt100 sensor.
The relationship between resistance and temperature is relatively linear, but
for measurements of very high precision, Pt100 working curve should be a
little bit improved. The paper describes an efficient way of measurement
characteristic linearization by using the analogue electric circuits. The
obtained results proved the initial considerations and the Pt100 becomes
rather transducer than pure sensor. |
