Digital temperature controller - PXF series

Thanks to their self-adjusting PID function, PID controllers PXF series automate the temperature control and management of industrial processes, saving energy and production scrap by eliminating temperature fluctuations.

  • PXF5 (48×96 mm)
  • PXF9 (96×96 mm)

Large number of input/output signals :

a wide choice of input/output signals

Wide choice of control methods (with auto-tuning) :

Examples of advanced control functions

on/off regulation schematic

ON/OFF control

When process value (PV) is below the set value (SV), output is turned on and the heater is energized as shown below.

When PV is SV, output is turned off and the heater is de-energized.

In this way, output is turned on/off repeatedly with respect to the SV to keep the temperature constant.

This method of control is called "on/off action" (or "two positions actions").

PID auto-tuning

PID parameters are automatically set by the controller's measurement and computation function.
This instrument provides 2 types of auto-tunning functions:
• the standard type (auto-tunning with SV used as reference)
• the low SV type (auto-tunning with the value 10% below SV used as reference)

Fuzzy logic control with auto-tuning

Fuzzy control is used to suppress overshoot so that the response to external disturbance is improved.
By monitoring PV, overshoot is suppressed with startup time remaining unchanged.
Also, disturbance can be settled quickly.
