The rotational speed sensor calibration device includes a mounting base, a gear rotatably arranged on the mounting base, an electric motor drivingly connected to the gear, a speed sensor for measuring the rotational speed of the gear, a control module electrically connected to the speed sensor and the electric motor, and a housing. The control module is used for performing negative feedback control on the rotational speed of the electric motor; a mounting position for mounting a to-be-detected sensor is provided on the mounting base, and the mounting position is arranged in the housing, and the electric motor and the speed sensor are located outside the housing. A thermocouple or a refrigeration component can be arranged in the housing to enable the to-be-detected sensor to be in different temperature environments.
