The utility model discloses a thermal flow sensor probe. The probe comprises a detection component and a main structure component, wherein one end of the detection component is arranged in the main structure component. With the adoption of the technical scheme, the probe has the benefits as follows: the probe is not limited within the micro flow range and can be used for measuring larger flows, and signals are stable and not affected by vibration easily; and meanwhile, the probe signals are amplified effectively, the response speed is increased, and high-accuracy wide-range flows can be measured.
