Abstract

PURPOSE: To make the temperature modulation amplitude invariably constant to the temperature fluctuation by varying the temperature of a basic temperature by using the program of a program circuit.
CONSTITUTION: The temperature in a thermostatic chamber 10 is detected by means of a thermocouple 12 and a linearizer 13. Of the detection signal; the basic temperature T component provided by a heater 2 is monitored by a low-pass filter 15, and the temperature modulation amplitude ΔT component provided by a heater 3 is monitored by bypass fiter 14 and an AC/DC converter 16. These monitor signals are input to a main controller 8' and a controller 9' for modulation respectively. The controllers 8' and 9' control power sources 6 and 7 for the heaters respectively so that the basic temperature T by the heater 2 and the temperature modulation amplitude ΔT by the heater 3 approach to preset values.
