1) Exercise

A PT100 sensor (resistance thermometer) is used to measure a variable temperature in the range –20 ° C to +130 ° C. See data in the above Table.

Calculate the temperature value [° C] when the resistance R(T) measures 92.3 Ω

Insert value α (1/° C)

Insert R(T) (Ω)

2) Exercise

A PT100 sensor (resistance thermometer) is used to measure a variable temperature in the range –20 ° C to +130 ° C.

Calculate the resistance R(T) value [Ω] when the temperature is 130 °C.

Insert value α (1/° C)

Insert value T (°C)
