Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to a full-automatic detection device for a digital pressure gauge. Background Art

[0002] A digital pressure gauge is a pressure gauge that uses digital display to measure the pressure value. Its working principle is that the measured pressure acts on the pressure sensor through the pressure transmission medium, and the pressure sensor outputs the corresponding electrical signal or digital signal, which is processed by the signal processing unit and then directly displayed on the display.

[0003] Currently, a Chinese utility model with announcement number CN210269015U discloses a pressure gauge testing platform, comprising a platform, to which a pressure tube and a hydraulic cylinder are fixedly connected. A piston is disposed within the pressure tube, which is connected to the piston rod of the hydraulic cylinder via a connecting rod and a threaded sleeve. A first connecting tube and multiple second connecting tubes are connected to the pressure tube. A reference pressure gauge is mounted on the first connecting tube, and each of the second connecting tubes is mounted with a pressure gauge to be tested. The device is designed to be able to test multiple pressure gauges simultaneously, addressing the time-consuming and labor-intensive nature of existing testing methods and their limited functionality.

[0004] In summary, compared with the above solutions, it is not able to effectively pressurize the air, and it is also not able to effectively and conveniently perform rapid testing on two digital pressure gauges at the same time. To this end, we provide a digital pressure gauge automatic testing device. Utility Model Content
