The FUJI temperature use FUZZY LOGIC technology to provide the best control quality. This approach prevents overshooting while reaching the set point is as fast as possible.
Beside the standard auto-tunig function FUJI controllers are equipped with the maintenenceless self-tuning function, what is very usefull when the set point or object heat inertion change frequently.
PXF temperature controllers
- Fast sampling rate – 50ms
- Control methods PID, SELF TUNING,FUZZY LOGIC, ON/OFF
- Inputs: TC, PT100, voltage, current
- Outputs: relay, SSR or 4-20mA

- Programmable ramps
- 32 types of alarms
- Easy switching mode auto-manual
- RS485 with MODBUS RTU as option
Other important features
- Heating – cooling mode,
- Programmable alarms (up to 3 point) – one of the 32 kindes each.
- Programmable heating ramps soak – up to 64 steps
- Programmable user key
- Programmable digital inputs – eg. change SV, start/stop ramp, eneble timers, change PID settings
- As an option the direct control of valve actuator
