8.3 PID control sample program
- PID control
When a K-type thermocouple is connected with the thermocouple input of FP-e, PID
temperature control can be easily conducted. (In addition, parameter setting can be
automatically selected using “AUTO TUNING.”)

- Thermocouple
A thermocouple is the sensor that measures the temperature using the thermo-
electromotive force generated by the temperature difference between two metal wires
connected, whose materials are different.
