Pressure transmitter measuring device

The utility model relates to the technical field of pressure transmitters, and discloses a pressure transmitter measuring device, which comprises a base, and a fixing plate is fixedly mounted at the left end of the top side of the base. The air pump is used for being connected with the air pipe on the front side of the connecting base and inflating, air penetrates through the inner side of the cavity, so that internal air pressure is increased, the movable plug is driven to move, the outer plate gets close to the connecting sleeve, the inner plate is adjusted on the inner side of the outer plate in a sliding mode, and then the outer plate and the inner plate are clamped on the inner side of the connecting groove. The connecting seat and the pressure transmitter body are sealed through the two sets of elastic sealing rings, so that the sealing effect in the using process is improved, a second rubber plate is pressed between a first fixing sleeve and a second fixing sleeve, the connecting end of a connecting pi
