High-precision digital display pressure transmitter and detection method

Abstract

The invention relates to a high-precision digital display pressure transmitter and a detection method. The transmitter comprises a bearing base, a connecting seat, a detection column, an insulating backing ring, a control circuit board, a bearing shell, a sealing end cover, a bearing column and a display. The upper end face of the bearing base is provided with a data transmitting cavity, the lower end face of the bearing base is provided with a detection cavity, and the upper end face and the lower end face of the bearing base are connected with the sealing end cover. The control circuit board is embedded into the data transmitting cavity, and the connecting seat is embedded into the detection cavity. The detection column is connected with the lower end face of the connecting seat. The sealing end cover on the upper end face of the bearing base is connected with the bearing column. The upper end face of the bearing column is connected with the outer side face of the bearing shell. The display is embedded into the front end face of the bearing shell. The detection method comprises the three steps of system assembly, pressure measurement operation and pressure value reading. The pressure transmitter can effectively meet the requirements of conveying operation pressure detection of various fluid media; and compared with traditional pressure detection equipment, the sensitivity and precision of pressure detection operation and the anti-interference capability in the detection process are greatly improved.

[0002] At present, when transporting or driving fluid media such as liquids and gases, it is necessary to use a pressure transmitter to detect the operating pressure of the medium. To meet this need, various types of pressure sensor equipment have been developed, such as the patent The publication number is CN212432381U, the publication date is 20210129, the application number is 202020531853.9, and the patent name is pressure transmitter and pressure transmitter system; the patent publication number is CN210953207U, the publication date is 20200707, the application number is 201921894812. Although a pressure transmitter and other equipment can meet the needs of detection operations to a certain extent, on the one hand, it can only meet the needs of specific medium detection operations during detection operations, and has poor flexibility and versatility; During the operation, the sensitivity and detection accuracy of the detection operation are poor, and the detection process lacks effective anti-interference ability and detection data verification ability, which leads to the relatively poor accuracy of the current pressure transmitter equipment detection operation, which is difficult to effectively meet practical needs
