The utility model relates to the field of temperature sensors, in particular to an explosion-proof temperature sensor. Explosion-proof temperature sensor, a temperature sensor probe body comprises a probe and a shell, the explosion-proof metal cable joint is characterized in that the shell is connected with the explosion-proof metal cable joint to form an inner cavity; the temperature switch is arranged in the inner containing cavity, the bottom of the temperature switch is parallel to and abuts against the cavity wall, close to the probe, of the inner containing cavity, the inner containing cavity is filled with heat conduction silica gel and tightly presses the temperature switch, and the temperature switch can directly exchange heat with the probe through the heat conduction silica gel.The structure is simple, and wide universality is achieved; the heat transfer performance and the heat conduction performance are faster and more sensitive; and when the built-in temperature switch reaches a set temperature
