Abstract

A temperature sensing unit and a temperature regulator capable of detecting whether or not erroneous setting of the type of a temperature sensor or erroneous connection has occurred are provided. As a temperature sensor for sensing the temperature of a controlled object, at least a resistance temperature detector and a thermocouple can be selectively connected to an input portion. A temperature sensing processing function portion processes a sensing signal of the temperature sensor connected to the input portion and acquires the temperature of the controlled object. A sensor type setting portion sets the type of a temperature sensor to be connected to the input portion. An erroneous connection detecting function portion detects whether the temperature sensor connected to the input portion is the thermocouple based on an inter-terminal voltage between connection terminals when the type of the temperature sensor set by the sensor type setting portion is a thermocouple.
