Sensor probe for pulse eddy current detection of heat exchanger tube bundle

The utility model discloses a sensor probe for heat exchanger tube bundle pulsed eddy current testing, which relates to the technical field of nondestructive testing and comprises a probe shell, a conical top cover is arranged at the upper end of the probe shell, a shell base is arranged at the lower end of the probe shell, and a mechanical iris component is embedded in the shell base. And one end of the core sensor assembly is connected with the conical top cover, and the other end of the core sensor assembly penetrates through the mechanical iris assembly and extends out of the probe shell. The technical scheme is simple in structure and convenient to install; the internal core sensor assembly is protected from direct contact with the inner surface of the tube bundle, and damage caused by the fact that the sensor collides with rust inside the tube bundle is relieved; the unique structure enhances the waterproof performance of the sensor, can be assembled and disassembled, and facilitates the free separation
