Abstract

The application relates to a cathode explosion block pressure drop measuring device for electrolytic aluminum. After the clamping mechanism in the open state is aligned with the object to be measured, the operating handle is used for sending a second instruction to enable the clamping mechanism to be switched to the clamping state, so that the measuring device is stably fixed on the object to be measured. And a data acquisition module electrically connected with the probe group synchronously acquires and records the measurement data of the probes. The operating personnel does not need to be close to an object to be detected (such as an electrolytic cell cathode explosion block) at a high temperature and a high position, and can complete the whole process of clamping, measuring and recording only through remote control of the rod body, so that potential safety hazards caused by climbing the high position or approaching a heat source of the operating personnel are avoided, and the safety of detection operation is improved.
