PURPOSE: A control device and a control method for a conductivity sensor are provided to include an electrode rod, a control unit, and a transmission unit in a single device and to electrically connect the electrode rod and the control unit with a spring, thereby improving the inconvenience and a failure rate of an assembling/manufacturing process. CONSTITUTION: A control device (140) for a conductivity sensor includes an input terminal, an electrode unit, and an output terminal. The input terminal supplies power to the control device. The electrode unit measures the conductivity and temperature. The output terminal converts signals of the measured conductivity and temperature into the data corresponding to a CAN communication protocol, thereby outputting the data. The input and output terminals are formed into structures which is electrically insulated from the electrode unit.
