5.1 TF-M-Pt100/TF-E-Pt100/TF-M-Pt100-VAL
Temperature Sensor
Type TF temperature sensors use a Pt100 temperature sensor
per DIN/IEC 751 class B to generate a temperature-dependent
resistance signal. The Pt100 sensor is installed at the lowest
point of the sensor tube to always ensure sufficient contact
with the medium being measured.
