Abstract

PURPOSE: To make it possible to control a temperature without offset by means of a simple constitution, by suitably voltage-dividing a set signal for setting the object, providing it to the pulse modulation amplifier, and designating the proportional band width of both the temperature rise side and the temperature fall side, conforming with the object to the controlled.
CONSTITUTION: An object signal which has been set by the variable resistor RP corresponding to the object setting graduation A of the controller is amplified by the linear amplifier OP1, and a part of its output is voltage-divided by the resistors RG, RE and is provided to the amplifier OP2. A control signal Ei is provided to this amplifier OP2, a deviation signal is output to the output of the amplifier OP2, and also the output of the amplifier OP2 is provided to the noninversional terminal + of the amplifier OP3 of the pulse converting circuit C. Also, the output of the amplifier OP1 is provided to the inversional terminal - of the amplifier OP3 through the variable resistor RF, the output EO of the amplifier OP3 is positive-fed back to the terminal + through the resistor R8, and also it is negative-fed back to the terminal - through the diode D and the resistors R5, R6. And, the voltage of the deviation signal is compared with that of the feedback point RF so that temperature control conforming with the characteristic of the object to be controlled can be performed.
