| description | The utility model provides a welding seam temperature detecting and recording device of a high-frequency welding pipeline for resisting harmonic interference of an intermediate frequency furnace. A first temperature sensor and a second temperature sensor of the device are vertically installed above a steel pipe, and a direct-current isolating switch power source is connected with the first temperature sensor, the second temperature sensor, a signal isolating converter and a CPU through cables. The first temperature sensor and the second temperature sensor are connected with the signal isolation converter through signal lines with shielding layers respectively, two output ends of the signal isolation converter are connected with the current AI module through signal lines with shielding layers respectively, and the network expansion module is connected with a network card installed in the industrial control host through a data line. And the industrial control host is connected with the display through a data li |
