4.10 Temperature sensor
Pt1000 is a platinum resistance temperature sensor (RTD), which is characterized by a resistance value of
1000
Ω
at 0
℃
. The corresponding temperature can be converted by measuring the output resistance value. The
relationship between resistance and temperature is shown in Fig. 4.25. The standard relationship between
resistance and temperature is as follows:
