Title:
TEMPERATURE CONTROLLER
Document Type and Number:
Japanese Patent JPS5672716
Kind Code:
A
Abstract:
PURPOSE:To improve temperature control capacity, safety, moisture resistance, and thermal resistance by constituting the thermistor of a heater wire by use of an ion conductive type high molecular temperature sensing element. CONSTITUTION:Between the 1st signal conductor 4 and the 2nd signal conductor 6, heat sensing heater wire 5 made of a thermistor is interposed and fluctuations of impedance due to fluctuations of temperature by the thermistor is detected by temperature detecting circuit 8 to control the operation of the switching element. Here, when the thermistor of heater wire 5 is composed of an ion conductive type high molecular temperature sensing element, the temperature control capacity, safety, moisture resistance, and thermal resistance can be improved.
