The TFRH/N is a high-end programmable
temperature sensor based on RTD technology.
The output signal is a Pt100 signal that can be
transformed to a 4 ... 20 mA output signal if a
temperature transmitter is built-in. Depending on
the type of sensor, temperature measurements
from -50 ... 400 °C are possible.
Programming can be done via the touch screen
display or via the FlexProgram.
