The present invention relates to a temperature measuring device using a resistance thermometer, and supplies the constant current to the RTD sensor, and measures the temperature by receiving a voltage corresponding thereto. In particular, it is provided for each type of RTD sensor inputs that may be selectively coupled to corresponding to the number of the wiring, and converts the terminal to supply a constant current to the RTD sensors, depending on the type of RTD sensor connected to the input terminal. For example 3-wire RTD, if the sensor is an A channel and a constant current supply connected between the B channel, and a four-wire resistance thermometer sensor when connected, supplies a constant current between the channel and a B channel. Accordingly, the temperature measuring device may measure the 3-wire RTD sensor and a 4-wire RTD sensors accurately be any of the temperature sensor is connected.
