Leakage-free detection device for nuclear island differential pressure transmitter

The utility model relates to the technical field of differential pressure transmitter detection, in particular to a nuclear island differential pressure transmitter leakage-free detection device which comprises a bottom support, an air inlet pump, a fixing device, a differential pressure transmitter, a connecting device, a detection pipe and a water storage pool. The air inlet pump is connected with a fixing device, the fixing device is provided with a differential pressure transmitter, one side of the fixing device is provided with a connecting device, the connecting device is connected with a detection pipe, and the detection pipe is connected with a reservoir. According to the utility model, air is pumped into the differential pressure transmitter through the air pump, whether the differential pressure transmitter leaks or not is judged through the rising and falling of the liquid level of the detection pipe, the air tightness of the differential pressure transmitter can be visually judged through the meth
