TEMPERATURE CONTROLLER FOR DEVICE SYSTEM PROVIDED WITH PLURAL TEMPERATURE CONTROL PARTS
PURPOSE:To save the energy with a temperature controller by comparing each measurement signal with a set temperature after the start of the temperature control of each temperature control part and feedback-controlling a heating means based on the deviation obtained from the comparison.

| description | PURPOSE:To save the energy with a temperature controller by comparing each measurement signal with a set temperature after the start of the temperature control of each temperature control part and feedback-controlling a heating means based on the deviation obtained from the comparison. CONSTITUTION:A control circuit (means) 15 as a control means is provided with a CPU 17, a ROM 19 which stores the action program of the CPU 17, a RAM 21 which stores temporarily the arithmetic process data on the CPU 17, and a data input/output interface (I/O) 23. A heater ON instruction device 43 connected to the circuit 15 turns on the heaters 13 set in the heating zones A - D of an extruder 1. When these ON actions are instructed, the measured value PV of a temperature measuring device 35 is compared with the set value SV. Then the circuit 15 functions also as feedback control to each heater 13 based on the deviation of the comparison. Consequently, the accurate temperature control is attained and therefore the energy is better saved. |
