The utility model provides a pressurized type temperature controller, which comprises an LWD series pressurized type temperature controller. The utility model is characterized in that a fixed seat provided with heat conduction grooves is arranged between a machine frame and a corrugated pipe. The inner parts of the heat conduction grooves on both sides of the fixed seat are provided with two heaters which are connected in series. Two end heads of the heater are respectively connected with a C terminal and an L terminal. The thermostat formed in the way can realize that the temperature controller can realize that purpose that the temperature of the corrugated pipe is higher than the temperature of a temperature sensing part under the condition of lower environmental temperature. The utility model is characterized in simple and compact structure, small size, easy implementation, etc.
